What are the causes for out of memory in weblogic?
How can we resolve except by increasing the memory size?
Is there any particular auromated scripts are there to alert the admins before out of memory arrives? If so please provide me.
where we can see the memory args in console?
thnx

Hi Venu,
OutOfMemory investigation is a very huge topic. Some of the related posts are available in http://middlewaremagic.com….still there are a lots of varieties we find in this kind of issues. It is always best to open a Ticket with Vendor Support team in case of any JVM Crash or OutOfMemory analysis. Because it requires a lots of data. Which is collected and analyzed using different tools and java_options.

Hi,
Can someone help me on how to rotation the LOGS in weblogic for applications?
Actually i was asked to rotate the logs like :
“rotate every 24hrs and store for 7 days”
Please help me where can i do this in weblogic side.
Thanks much

Hi Jay,
Yeah – You’re correct.
Everything seem to be default in the console.
Let me explain exactly what’s my issue –
I tried deploying the code , but its failing with error like
Deployment service servlet encountered an exception while handling request of type “app_upload”.
Exception is: “No space left on device”./app/ample.ear’ for application ‘ample’. The specific error is: No application files exist.
So I’ve loggind into the LINUX machine , and observed as /opt filled to 100%
Setup of my project:-
OS : LINUX machines
Domain path : /opt/weblogic/domains
Logs path : /opt/weblogic/logs
What makes my /opt filled 100% ? – observed like particularly this application “ample” writing huge logs as
11G – /opt/weblogic/logs/ample
And we have logs of june , july and present august , SO I’ve cleaned up the logs of june & july – and now /opt down to 70%.
And finally i’m able to deploy the code successfully.
Now the client asked me to rotate the logs like “rotate every 24hrs and store for 7 days” – To my understand i think with this rotation , the logs would store upto 7 days only
I am not sure where we can apply this , initially even i observed the console which you have mention here , but thinking can we do it somewhere in server side?
Please let me know incase of clarifications
Thanks
-Arun
August 12th, 2010 on 9:50 pm
Okay – so making changes on console side means as you told previously the steps would work?
Those initially steps would satisfy my client’s request ?
Right ? Or do we have any other location on console to update this logs ?
Please let me know
Thanks.

Hello Wonder team,
I have an application that is running on Weblogic 9.2.2 on unix platform. The application that i work on interacts with another application to transmit/recieve data over a webservice. My application is using weblogic webservices to generate the client (stubs) code. The application that we interact with has three different webservice calls out of which the client application (My application) is able to unmarshall or de-serialize the webservice response. However the response of one call is unable to be de-serialized.
When i turned on the weblogic webservice debugging and reviewed the incoming soap response which the client application is unable to de-serialize, i found that the namespace prefix is missing from each node.
The response which the client applicaiton is able to de-serialize successfully has the namespace prefix to each and every node of the web service response.
Does weblogic 9.2.2 require a namespace prefix to be present at each and every node. Is there a way for the client application to de-serialize the response correctly even if the namespace prefix is not present in each and every node. I apologize for not giving you any log info. I will update with the log info tomorrow but if i was able to explain the problem clearly any inputs from you experts will be greatly appreciated.
Regards,
Surya
August 18th, 2010 on 11:11 am
Hi Surya,
At the client side you can add a WebService Handler with the following code to remove the NameSpaces from the XML message:
Option1). U can force the Stream to use the default Namespace at client side:
HashMap NamespaceMap = new HashMap();
NamespaceMap.put(“http://your.desired.namespace/”, “”);
XmlOptions xo = new XmlOptions();
xo.setLoadSubstituteNamespaces(NamespaceMap);
xo.setUseDefaultNamespace();
System.out.println(yourXmlDoc.xmlText(xo));
Option2). You can add a Name Spce in the XML message at the Client Side Handler…using XMLCursor:
XmlCursor cursor= targetObject.newCursor();
cursor.toNextToken();
cursor.insertNamespace(“myprefix”, “http://my.name.space”);
cursor.insertNamespace(“xsi”, “http://www.w3.org/2001/XMLSchema-instance”);
cursor.dispose();
.

Thanks Jay for your response. If you don’t mind i would like to understand why should i be writing a handler and why does weblogic not process the weblogic response if the namespace prefix is not included in the soap response.
If you can clarify this it will help me understand the issue better.
Thanks for your time.

Hi Schinta,
Ideally WebLogic generated Clientside artifacts should be able to process both the responses (with or without NameSpaces). But i m surprised that…Why and How the WebService operation is developed in such a way that 2 Operations will have the NameSpaces and 1 operation is without having the NameSpace?
Have u generated the clientartifacts using the “clientgen” utility recently. I just wanted to make sure this because sometimes if we change any NameSpace…then We Must regenerate the Client Artifacts.
Can u please let me know one more thing…your Client Side artifacts are JAXWS or JAXRPC type? WLS9.x doesnt support JAXRPC WebService …but It is Possible to deploy the JAXWS Client in WLS9.x…. So i just wanted to make sure that your ClientSide Artifacts are JAXWS style or JAXRPC Style?

Hi Jay,
Thanks for the response. I posted a response to your comment but was unable to see it. So attempting to send my follow up questions.
Is there an apparent bug with weblogic 9.2.2 while processing soap responses with out the namespace prefix ? Ideally i don’t want to be writing a Handler to process the incoming response. I am told by the service provider whom we interact with that they are able to process the soap response even though there is no namespace prefix. But they are using axis 1.4.
I would like to understand why weblogic doesn’t parse the incoming soap response without namespace prefix and if there are any alternatives to resolve the issue without writing the handler, i would like to review that.
Once again i sincerely thank your quick response.

Surya

Hi Jay,
I have always used weblogic’s clientgen to generate the stubs. and as per weblogic documentation it reads “Clientgen Generates the JAX-RPC Service stubs and other client-side files used to invoke a Web Service”
Regards,
Surya
August 20th, 2010 on 1:25 pm
Hi Surya,
Yes, you are right in WLS9.x “clientgen” you wont see any option to generate the JAXWS stype of Artifacts … This feature is available from WLs10 onwards …where you can specify the type=”JAXWS” or type=”JAXRPC” to generate different types of Artifacts for Client.
but i m much interested to know Why & How your WebService has 2 Operations with nameSpace and One Operation without NameSpace…If i will be able to know this then i can try to reproduce this issue at my end to debug this issue.

Hi Jay,
As mentioned in my original problem, I am just the consumer of the webservice. When i consume the webservice from the webservice provided,
I have observed in the weblogic.out ( after turrning the soap debugging) that one response doesn’t contain the namespace prefix and other contains the namespace prefix
My understanding is that this is a service provider issue. However, i also want to understand why is the soap response not being de-serialized.
Any insight from you will be greatly appreciated.

Hi Surya,
I have sent you a TestMail in your Gmail address. You can reply to that with your SOAP Request/Response text. I was just wondering if you can send me the WSDL file of yours then it will be really great. I will try to Generate a Mock WebService from that WSDL to see WHy & How the Name Spaces are available for 2 Operations but not for the Third Operation.

Hi Surya,
It looks like there is something seriously wrong with the WebService or the WSDL …Because When I used WSDLC on your WSDL file to generate a Mock webservice … I Saw that that is only one Single Operation available inside your WebService Like following:
(Description of WSDLC: http://middlewaremagic.com/weblogic/2009/12/18/how-to-build-a-webservice-from-a-wsdl/
AND
http://middlewaremagic.com/weblogic/2010/04/04/building-jms-based-webservice-suing-top-to-bottom-appraoch/)
——————————————–
package ws;
import javax.jws.WebService;
import weblogic.jws.*;
@WebService( serviceName=”ACSService”, targetNamespace=”http://www.openuri.org/”, endpointInterface=”ws.ACSServiceSoap”)
@WLHttpTransport(contextPath=”ACSService”,serviceUri=”ACSService.jws”,portName=”ACSServiceSoap”)
public class ACSServiceSoapImpl implements ACSServiceSoap {
public ACSServiceSoapImpl() {
}
public com.oriservices.creditdecision.v031704.ResponseDoc executeBusinessAction(com.oriservices.creditdecision.v031704.ActionDoc actionDoc)
{
return null;
}
}
——————————————–
I can see only one Operation (Method) generated using the WSDLC task. Are u sure that u are using the Correct WSDL? I am sending you the ANT file which i used to generate the MOCK Service from your WSDL. Attached in the Mail…
Please run the “setWLSEnv.sh” before running the ANT script attached.

Customer is facing Slow WLST Response on WLS 9.2 mp2,
If he undeploys the application from the console, it takes 1 minute, the same application takes 15 minutes from WLST to undeploy. Issue is occuring in production.
The same does not happen in their test environment,
The following config (config.xml) in the managed server, when added to our testing environment (which originally only exists in production env.), slowed down the undeployment process from 1 minute to over 15 minutes:
thread-pool-percent-socket-reader 50 thread-pool-percent-socket-readers
ssl
login-timeout-milli 25000 login-timeout-millis
ssl
stuck-thread-max-time 200 stuck-thread-max-time
We suspect 50 is the problematic tag,
please help us understand why this issue happens.
Looking forward for your assistance.
August 24th, 2010 on 4:23 pm
Hi Arun,
There is nothing wrong with the WLST or WebLogic Server. We need to perform the OS tunning in this case. Please tune the following two Parameters at OS level: (Compare the following Parameters in your Both the Environments at OS level…)
1). Disk I/O
2). Swap Space
3). Increase the FileDescriptor Numbers (to Minimum of 8196 using “ulimit -n”)
WLST loads many classes and connects to the remote server to depoy/Undeoploy applications. Which requires sufficient File Descriptors to be available.

Hi Vivek,
Please post your Install Windows Service script. Looks like there is something wrong. Also Make sure that the Windows Service name is correct. It means the WindowsService naming convention is “%DOMAIN_NAME%_%SERVER_NAME%”
Example Syntax :
“%WL_HOME%serverbinbeasvc” -install
-svcname:”beasvc %DOMAIN_NAME%_%SERVER_NAME%”
-depend: “beasvc myDomain_myAdminServer”
-delay: “800”

Hi Rakesh,
If you will see the below line of Exception:
java.lang.NullPointerException at com.nvd.saa.SaaCache.hashSQL(SaaCache.java:333) Which clearly indicates that the NullPointerException is being thrown by your Application Code “SaaCache.java” at line number 333. So first of all you need to put some System.out.println() statements before and after that line of code to findout which object is actually becoming NULL. Then only you will be able to find out why the Object is Becoming NULL. As this error has nothing to do with WebLogic …your Application Developers will be able to Find out the cause.

Hello Admin,
I am unable to start managed servers in weblogic 10.0 in development env in windows.
I have created managed servers from both the config wizard and also through admin console and assigned them to clusters. First time they start normally to RUNNING MODE. But after a few seconds, it changes to FAILED. And when i start again, they stay in FAILED state itself.
I never had a problem in weblogic 8.1, but 10 seems to be different.
I have assigned both the managed servers to the same machine and also to the cluster.Didn’t assign the admin server to any machine or cluster.
Also, i get this following message in the admin server command prompt.
Can you help please

Hi,
We have 1 cluster with 2 managed server running on the same box.We use HP openview to monitor the state of the servers.SO whenever any one of server goes down, we get an email alert and then we manually restart them.The problem is we want to automate this problem. I mean whenever any instance goes down and Hpopenview detects it ,servers should be started automatically.
Any guidelines or instructions for this?
Thank you
October 16th, 2010 on 11:09 pm
Hi SinghJ,
Please configure your HP Openview tool in such a way that as soon as it detects the Failure of any server it executes the ANT script : http://middlewaremagic.com/weblogic/2010/03/08/starting-stoping-servers-using-ant/ to start the Failed Server.
Even u can use the JMX Approch to detect the Server Failure and using JMX only u can start the Failed Server: http://middlewaremagic.com/weblogic/2010/06/22/getting-all-server-state-info-in-9-x-jmx-style/

As far as the load on this server box, this is a development environment and it never had any peak loads. The heap is almost always 70% free. We use 1GB as heap size for each JVM and we have 2 JVMS in the same box.

Hello Jay:
You people have made somethings so easy for my new job. I learnt quite a bit from this website. Have few questions in WebLogic. I will post one by one.
We use a log4j.properties file instead of a log4j.xml file for logging. The log4j.properties file is placed in a location on the server and that path is added to the Weblogic classpath for it to load at startup.
The log4j logs are written sometimes and are not written sometimes to the output.log file. THIS IS MY ISSUE.
This development environment has been in use for over 2 years and the developers are saying we are seeing this issue recently. We are using WebLogic 9.2 MP3 on Solaris.
Here is a copy of our log4j.properties file. Hopeful you can spare some time for my issue.
============
log4j.rootLogger=debug, console, file
log4j.logger.org.apache=warn
log4j.logger.org.directwebremoting=error

October 19th, 2010 on 9:20 pm
Hi Nagapavan,
Your “log4j.properties” file looks very good, I don’t see any issue in that. WebLogic Allocates some threads for logging may be sometime due to heavy load on the Application/Server some logs are not getting logged. Have u observed any such scenario when there was load on the Server and Logging didnt happened at your environment? Or Is it happening when the Operating System has a High I/O count?
How frequently this issue is happening? Have u tried to update the log4j.jar and it’s related Jars…I mean have u tried with the latest log4j Jars? Because configuration wise i really don’t see any issue.

Hi Mauro,
All I guess at this Moment… It looks like u have some EAR Application in which u implemented some “ApplicationLifeCycleListener” And Your code is trying to Access the EJB Reference inside the preStart() or postStart() method of that Listener. In a Clustered Env when u are trying to stop your Application that time the EJBs are getting undeployed first so the postDeploy() of your Listener may be getting the Null reference of the EJB ….
Above all is my guessing so far from the StackTrace…. U need to check your ApplicationLifeCycleListener. You can check it inside your “<EAR_FILE>META-INFapplication.xml” Is there any Listener defined or Not….If yes then That Listener is actually causing the issue.

Thanx Jay for ur reply, i have a listener defined in my application-weblogic.xml
And i use this ApplicationLifeCycleListener in the startup of my app with the postStart method to init loggers and params load from data base.
But i dont use the preStop or the postStop method of this ApplicationListener.
Thanx for ur reply again
November 12th, 2010 on 9:51 pm
Hi Mauro,
I again lookedup at the Exception Trace … This time i suspect that there may be something wrong with the EJB which is available as part of “AlertasEJB.jar” as well… because i can see that the Deployment (Not undeployment) time exception:
1). Is this Jar/Application getting deployed properly in a Non-Clustered Environment?
2). The EJB/EJBs which are placed inside this “AlertasEJB.jar” all the EJBs have been decalered as <home-is-clusterable> And/Or <stateless-bean-is-clusterable> or similar Tags for all the Beans? Inside “weblogic-ejb-jar.xml” file

Hello Jay,
1) the server is a clustered environment… there are 2 clusters in the server
2) inside weblogic-ejb-jar.xml i dont have those tags that u mention 🙁
Are those tags necessary in a clustered server?
November 12th, 2010 on 11:51 pm
Hi Mauro,
It depends on which kind of bean we are trying to deploy. Stateless/Stateful/Entity…. Please refer to know more on this Why and wneh these tags are required…: http://download.oracle.com/docs/cd/E12839_01/web.1111/e13719/ejb_jar_ref.htm#insertedID110

Hi Floks,
I need some pointer for taking a Thread dump while JVM crashes.
I was wondering like we have two option one is OnErrorShowMessageBox and onError these option.
Where showmessagebox is not recommended for OS like Unix base.
So is there any alternate way to take thread dump or we can create our custome debug to take thead dump or take multiple operation of java.
Hope I put my query in correct.
Reagrds,
Kal.

Hi Vigaros,
Yes all the WLST Scripts present in middlewaremagic can be used just by copying and pasting it in any suitable editor. As earlier we just uploaded the Screenshot of the WLST Script to to get the Application State, you were not able to use it properly, So now we uploaded the Code version of the same script in the post. http://middlewaremagic.com/weblogic/?p=1473
We have sent you a copy of the same WLST Script in your E-Mail, you can use that as well.

Hi MWM,
We have installed 32-bit installer of Oracle WebLogic 10.3.3 + OFMW 11g (11.1.1.3) in Solaris Sparc 64-bit machine.
My query here
1. What are the implications of using a 32-bit installer in 64-bit server?
2. Will there be any performance issues?
3. Should the Java code base be build by 32-bit jdk as 32-bit installer uses 32-bit jdk within itself.
I request you to clear my doubts.
Thanks,
Babu
November 18th, 2010 on 11:46 pm
Hi Babu,
Generally, the benefits of being able to address larger amounts of memory come with a small performance loss in 64-bit VMs versus running the same application on a 32-bit VM. This is due to the fact that every native pointer in the system takes up 8 bytes instead of 4. The loading of this extra data has an impact on memory usage which translates to slightly slower execution depending on how many pointers get loaded during the execution of your Java program. The good news is that with AMD64 and EM64T platforms running in 64-bit mode, the Java VM gets some additional registers which it can use to generate more efficient native instruction sequences. These extra registers increase performance to the point where there is often no performance loss at all when comparing 32 to 64-bit execution speed.
The performance difference comparing an application running on a 64-bit platform versus a 32-bit platform on SPARC is on the order of 10-20% degradation when you move to a 64-bit VM. On AMD64 and EM64T platforms this difference ranges from 0-15% depending on the amount of pointer accessing your application performs.
The maximum theoretical heap limit for the 32-bit JVM is 4G. Due to various additional constraints such as available swap, kernel address space usage, memory fragmentation, and VM overhead, in practice the limit can be much lower. On most modern 32-bit Windows systems the maximum heap size will range from 1.4G to 1.6G. On 32-bit Solaris kernels the address space is limited to 2G. On 64-bit operating systems running the 32-bit VM, the max heap size can be higher, approaching 4G on many Solaris systems.
As of Java SE 6, the Windows /3GB boot.ini feature is not supported.
If your application requires a very large heap you should use a 64-bit VM on a version of the operating system that supports 64-bit applications.

Hi Admins,
Could you please help me with the answer of the following question regarding JDBC connection pool?
Q. I have 10 database connections in my WLS JDBC connection pool with maximum capacity defined as 10. All 10 connections are in use now. What happens if the 11th database connection request comes?
Thanks
Sanjay
December 2nd, 2010 on 6:19 pm
Hi Sanjay,
If Max Capacity of the connection pool is 10, And if all the 10 connection objects are being used by 10 Different clients. Now when the 11th client requests for a database connection from the Datasource …In that case the Client will get “ResourceLimitExceededException” thrown by the Connection Pool.

hello Admin,
the env is weblogic 9.2.2.0, in windows 2k3 and in windows QA environment.
I am trying to start the admin server. Since the env is QA, after i go to start and bea products and start the admin server, I enter the weblogic username and password at the command prompt,
it loads the license file “license.bea”
then the server state is changed to STARTING
it initializes the self-tuning thread pool and then
it gives the log management,
and after this this there is no processing ahead, it gets stuck there
The ADMIN SERVER isn’t starting. i waited for 1 hour and tried it several times. It didn’t start.
I checked the log files, and what i could notice is that there was only 1 access.log, one AdminServer.log and one Domainsaaqa.log file and these log files are up to 4.5 MB each.
There are no other log files. like access.log070, etc. I am guessing that the log files arent being rotated. Is there a way to correct this ???
so, is this causing the problem or is there any other reason ?
if that is the problem, is there a way to increase/rotate the number of log files ?
if the log file thing is not the reason, then can you please help me out with this issue ?
thanks

Please send us all the contents present inside the “config” directory present inside the “<DOMAIN_HOME>” and also please collect at least 4-5 thread dumps taken in the interval of 9-10 seconds each (Thread dumps must be taken at the time when server is not responding). Also please send us the Admin Server Log Directory contents as well.

Thanks Jay,
Just solved the issue.
What happened:
the admin server was stuck after log management step and it just hanged there. it wont go to the security step.
In the log file, the last step i can see was
IIOP Subsystem enabled.
So, i thought may be the ldap is corrupted
So, i renamed the ldap file in the admin server’s data folder.
Then, when i started the admin server, and after giving the details, it started creating a new ldap directory.
this solved the issue
Thanks Jay for your time and support

Hello magics,
I want to get how much seconds a transaction (mostly XA) lives on weblogic.
There is a way on console:

hello Jay,
is there a way to apply patches to weblogic without restarting the admin server of the weblogic server ???
December 15th, 2010 on 11:27 pm
Hi Rakesh,
We are sorry to say but without restating all the servers the patch would not be applied as because weblogic has already loaded the buggy classes in it’s classloader, thus to we have to restart the servers to let them know that there is a new class which is available and weblogic would load that.
However to avoid the down time for the application in production environment you can use the Rolling Bounce the servers (i.e shut-down one server and then restart it again so that other servers in the cluster can handle the load for the application and then do the same thing with other server one by one)
Note: The patch is only applied to those servers which have been restarted
Hope above information would help you.

not located in the web of oracle-download page….
thanks
December 22nd, 2010 on 10:48 pm
Hi Vigaros,
“Gurdian” tool is now available to download via a valid support contract with Oracle. It is not publicly downloadable. Once you login to the Oracle Support Portal, The Guardian resource center is located in the knowledge link/tab of My Oracle Support under “Tools and Training” > “Diagnostic Tools”
You must have a current support contract with Oracle for your BEA software in order to download Signature Patterns and Guardian product updates. Sunit has pointed the correct link above.

hello admin,
the env is windows with weblogic 9.2.2 in dev env
We have a 16GB RAM and 80 GB hard drive on a VM where weblogic is installed.
So, i increased the memory arguments to 2048m as in -Xms2048m and -Xmx2048m for the domain and while starting the server, it says this error has occurred
Error occurred while initializing the VM
Could not reserve enough space for object heap
could not create the Java virtual machine
so what is the reason for this ???
is this because the maxpermsize is still 128, or something ???
i tried to increase that too, but didnt work
can you help me resolve this
Thanks in advance

Hi,
In Windows 32 bit Systems you can not assign that much heap. It will start crying at 2GB. Please refer to the post: http://middlewaremagic.com/weblogic/?p=4456
The Theoretical limitation of Maximum Heap size for a 32 bit JVM is upto 4GB. Because of the Memory Fragmentation, Kernel Space Addressing, Swap memory usages and the Virtual Machine Overheads are some factors JVM does not allow us to allocate whole 4GB memory for Heap in a 32 bit JVM. So usually on 32-bit Windows Operating Systems the Maximum can be from 1.4 GB to 1.6 GB.
.
If we want a Larger memory allocation according to our application requirement then we must choose the 64-bit operating systems with 64 bit JVM. 64-bit JVM provides us a larger address space. So we can have much larger Java Heap with the increased number of Threads allocation area. Based on the Nature of your Operating system in a 64 bit JVM you can even set the Maximum Heap size upto 32GB.
Example: -Xms32g -Xmx32g -Xmn4g

Hi Rakesh,
It’s a Clear Application error not the WebLogic Issue…see the below method execution which is happening while the error is occuring:
com.bsi.control.document.DownloadDocumentFileCommand.processCommand()
So you need to ask your Application Developers to look into the “DownloadDocumentFileCommand.java” class processCommand(). If your developers can put some Debug inside this method to findout from which location it is trying to download the Files, then the issue will be resolved in minutes.

I checked the admin console but it inst showing up.
I wanted to restart the domain. But when i am trying to stop the admin console, it is showing some error.
I was trying to delete the AdminServer.lok file from the tmp folder in the domainservers.
How do i restart my admin server. I cannot get into the admin console as the console isnt working. but one of the applications deployed onto the managed server is working.
here is the layout:
weblogic production env 9,2,3 in windows 2k3 server.
Admin Server is present in one prod server vm, the application is clustered on to other two physical servers.
Thanks for the help in advance. How do i restart my server

In the Admin Server.log, its not showing anything. The last activity on it was on Jan 2’nd and after that nothing.
The server is running but i am unable to stop it or restart it.
When i try to stop the server, i cannot as it is showing some error and closing the command prompt automatically. When i try to start it, its showing the lock error and according to some forums, i tried deleting the AdminServer.lok file it is not gettting deleted saying that it is being used by other programs.
There is a node manager service for 9.2.3 running, i tried to stop it and delete the AdminServer.lok file, but i couldn’t delete it.

Hello Jay,
is there a way to rename the password in the production environment.
The env is weblogic 9.2, windows production env.
The Admin Server for a domain is running in prod env, but i cannot see the admin console when i start it. when i try to start it from the start menu, it says server lock, which implies the Admin Server is running.
I tried to stop the server, but in order to do that, we need the username and password. But we dont know the password for the admin console for that domain.
Is there a way to change the password, without stopping the server.
like creatinga new user using a script or something so that we can login into the admin console
???
Thanks in advance

January 22nd, 2011 on 11:03 am
Hi Rakesh,
You can use the below mentioned steps to Change the Running AdminServers account:
Step1). open a Command Prompt and then run “setDomainEnv.sh” or “setDomainEnv.cmd”.
Step2). Just for Safety Take a Backup of (C:bea103user_projectsdomains7001_Domainsecurity*DefaultAuthenticatorInit.ldift*) file …because in the Next Command which we are going to run is going to Create a New File “DefaultAuthenticatorInit.ldift”.
Step3). In the Command Window Move inside your Domain’s Security Directory…And then Run the Following Command:
Example:
C:bea103user_projectsdomains7001_Domainsecurity>java weblogic.security.utils.AdminAccount newAdmin newPassword .
Syntax: java weblogic.security.utils.AdminAccount <NEW_USERNAME> <NEW_PASSWORD>
NOTE:- There is a . (DOT) at the end of the Above command which represents the Current Directory. Here you can see that after this command Executes A new “DefaultAuthenticatorInit.ldift” file will be created in the Current Directory.
IMPORTANT STEP [This Step 3-A) U Need Not to Follow If you Already Forgot your Admin Credentials]

Hi Arun,
The error code BEA-000123 has the following description
Description:
You tried to bind an object under the name bindName in the JNDI tree. The object bindObject is non-clusterable, and you have tried to bind more than once from two or more servers. Such objects can only be deployed from one server.
Cause
Your cluster is not homogeneous. Two servers in the cluster are providing different services under the same name bindName. If the object is non-clusterable, only one server in the cluster can provide this service.
Action
There are various options.
1. Make the object clusterable.
2. Change the JNDI name of the object under which it is bound.
3. Make sure the object gets deployed only on one server.
4. Deploy the service on all the servers.
However, when you bind it into the JNDI tree, set the replicate bindings property to false.

Hello there admins, its been a while since i post last time…
I have a new question for u related to logging, im using weblogic 10.2
My ear have an app.jar (with ejb3) and a webapp.war and i use log4j for logging in both. My problem is that logs generated in mi webapp.war are not been logged. But logs from app.jar yes… i setup log4j configuration in both applications.
There is some reason why app.jar is registering logs and my webapp.war dont? i really need to register action in webapp.war 🙁 but the only thing registering in my webapp.log is when i run the application for the first time, but request to servlets dont.
If u have and example with log4j for and ear with ejb and war logging in separate files i will be very grateful.
Thanx in advance for any help

” If you want to use separate log4j configuration files for Web applications and the EJBs, you have to place the Web application’s log4j file in the /WEB-INF/classes folder, and the EJB’s configuration file in the individual .jar files. This way the Web application will have visibility of its own log4j configuration file through its own class loader, and the EJBs will get their log4j configuration file through their individual class loader”
Can u explain me please what it means the next “and the EJB’s configuration file in the individual .jar files” ? should i put the log4j-ejb.properties next to META-INF and WEB-INF folders inside my ejbapp.jar? or inside WEB-INF?
For the record i put log4j.jar inside APP-INF/lib
After that how can i load log4j-ejb.properties and log4j-web.properties inside my java code?
Like this?
For EJB Module:
java.net.URL url=Thread.currentThread().getContextClassLoader().getResource("log4j-ejb.properties"); PropertyConfigurator.configure(url);For Web Module:
java.net.URL url=Thread.currentThread().getContextClassLoader().getResource("log4j-web.properties"); PropertyConfigurator.configure(url);And if i load the properties files from a directory… should i do it this way?
For EJB Module:
PropertyConfigurator.configure("./apls/TestProject/configs/log4j-ejb.properties");For Web Module:
PropertyConfigurator.configure("./apls/TestProject/configs/log4j-web.properties");Thats all i have…
thanx in advance for ur help…

Hi Mauro,
Sorry for replying very late…I was quite busy for couple of days.
Reagarding separate Log4j Logging for different applications …there any many conflict statements present in google. I simple prefer using two separate log4j.xml files for logging my application data.
I developed a Simple Testcase which has a simgle “lig4j.jar” inside “EARAPPAPP-INFlib” and the EAR application contains one EJB Jar and a WebApplication. Both have their own log4j.xml files like “webLog4j.xml” and “ejbLog4j.xml”
I strongly suggest the above technique to generate separate logs ….Please try the TestCase which i uploaded in the following location: http://www.4shared.com/file/7ZQ4sjqn/SeparateLog4j_Logs_ForApps.html
Please lets us know if this is OK for you. It’s working fine for me and maintaining separate logs.

Hi Jay,
Environment: QA
Weblogic: 10.3.0.0
JVM: Jrockit
Environment: Red Hat Linux
Background:
We had QA deployment on 02/04/2011. After that I restarted all 3 nodes one after the other.
Today, I observed that console logs of node-2 and node-3 are updated but node-1 console logs show Feb-05.
Infact, node-1 is not reachable, even though the state shows “running” in console.
This is the last thing I see in node-1 logs:
How do I troubleshoot this issue?
Restart node-1? But what could be the rootcause??
February 7th, 2011 on 11:35 pm
Hi Pradeep,
Please file a Console Bug with Oracle Support. Also if next time you want to get the correct status of server then try JMX or WLST. Donot trust on Admin Console. Many people have reported similar issue. But Oracle support was not much helpful in this case because this issue is very intermittent means 1/1000 cases.

February 8th, 2011 on 12:27 am
Update:
Thanks Jay. I think you are correct. Because once I restarted node-1, the logs got updated. For now, I think the issue is fixed, but, I will surely open a case with oracle to see if they have some kind of fix for this issue.
BTW, did you observer this only in 10.3.0.0 or even in other versions as well???
Thanks,
Prasad
February 8th, 2011 on 12:45 am

Once i saw one ticket (when i was in oracle support ) it was raised on WLS10-MP1 for the same issue.

hi,
Not sure where to start a new thread so posting question here
can someone please let me know how to determine the amount of memory that can be used by weblogic server on a host that has say 32 gb ram,or 64 gb ram?
is there a weblogic recommended theorotical calculation formula to figure out this number and ofcourse later on tune the server based on application req?
also, memory calculation based on processor bit size (32, 64 bit processor…i think there is a calculation something like 2 power 32 etc..but forgot the formula) and based on number of processors?
thanks in advance

hi jay and team,
I have small problem.I have a war file which has been deployed on weblogic 10.3.3.Its working fine.
The problem is when ever the user logs in to the application and access the database and then logs out from the application.
The thread of the user is still present even though he has logged OUT FROM T^HE APPLICATION.ie the thread for that user never get killed even if he logs out.
Is there any option which needs to be enabled or disabled in weblogic.
Because in a day if 300 -400 user gets logged in.Then at the end of the day,there are 300-400 active threads,even if the seesion is zero..
which is hampering the performance
Pls help,
Thanks in advance
Regards
Fabian
February 25th, 2011 on 6:00 pm
Hi Fabian,
From WLS 9.x self-tuning threads were introduced which would grow and decrease automatically, depending on the load. So if more users are coming in then more threads would be produced and once WLS notices it that now there is no need of these threads it would get reduces automatically.
Topic: Server Self-Tuning for Production Environments
http://download.oracle.com/docs/cd/E13222_01/wls/docs90/notes/new.html#1216270
However if you need to restrict this feature and want to define a number then you would have to go with workmanager, to get more information on that check out the below link.

2) Similarly if i am planning to move only second managed server Hello2 to IP 172.XX.XXX.108.. How will i do it…Could you please answer me. Thank you in advance.

Hi Tom,
The best way to achieve your requirement is to use the Domain template builder. To get more information have a look at the below links.
Topic: Creating Templates By Using The Domain Template Builder
http://download.oracle.com/docs/cd/E13179_01/common/docs103/tempbuild/index.html
Topic: Overview of the Domain Template Builder

Topic: Creating Domain Templates by Using the Domain Template Builder
http://download.oracle.com/docs/cd/E13179_01/common/docs103/tempbuild/tempbuild.html#wp1095888
Few things to remember:
1) Few things like JMS file store, log files etc would not be transfered with it, so take a backup of the original domain.
2) You should have WLS installed on the new box (172.XX.XXX.105).
3) Once you create a new domain using the template from the old domain which was having the previous configuration you have to change the startWeblogic.cmd/sh and give DOMAIN HOME with the new domain home on the new box (172.XX.XXX.105)
4) During creating the new domain using the template you can customize few things which you want for the new domain like IP address, Create more servers etc.
Let us know if you need any more help on it would try our best to help you with it.

Hi Fabian,
This is regarding your previous query. http://middlewaremagic.com/weblogic/?page_id=2594#comment-2980
Did you notice that the issue is happening only in Internet Explorer and the same thing works fine in FireFox?
Try Fire Fox browser to see if it works fine..For me things are correct in ForeFox and the issue occurring only with IE only.
Means only in Internet Explorer only you will see that the Microsoft Word Document/ Microsoft Excel Sheets are directly being displayed in the WebPage on the browser. But in Firefox as soon as you click on the Link which points to a Word Document it Asks us to Open or Download the Word Document.

March 6th, 2011 on 12:06 pm
Hi Fabian,
It is not necessary to use node manager to start a cluster and its perfectly fine to use the startup script of Managed server to start a cluster as the given command below
StartManagedWebLogic server_name t3://IP-address:port
where:
server_name:- is the name of the Managed Server you wish to start
IP-address:- is the IP address or DNS name for the Administration Server for the domain
port:- is the listen port for the Administration Server for the domain
Example:
StartManagedWebLogic MS-1 t3://10.10.10.10:7001

hi,
Thanks Jay and Ravish..
Im stuck in a small problem.
I have deployed a war file and the application is running fine.Now I have problem is while monitoring the application.Ie i need to find how many users are logged in(this i can find through goin to deployment–>clicking on the war file–>monitoring–>Webapplication–>session)but now how can i find the ipaddress of the user logged into the application.
I checked all the tabs under monitoring,but neva found any.
This command gives all the user accessing the application
netstat -an|grep 7003(managed server port)
but is it possible through console??
This was possible with OAS10g release2,from the console itself
Pls help
Regards
Fabian
March 9th, 2011 on 4:41 pm
Hi Fabian,
If you want to know the IP-Address of the Client who are hitting your application you can achieve that by going to the below console path
Servers –> -> Logging –> HTTP
Click on the Advanced link and add cp-i in “Extended Logging Format Fields:” and save it.
Example:
cp-i date time cs-method cs-uri sc-status
Now when the client hits your application and then you can get the IP-Address of the client in the access.log which can be found in “/servers/SERVER_NAME/logs”.
Note: access.log would not start writing till default size which is 8kb to passes, so you can use following parameter in the start-up script to start writing from the first hit
-Dweblogic.logging.bufferSizeKB=0
And for for session monitoring you can check out the below posts
HttpSession Monitoring using
Session Monitoring Using WLDF

hi Ravish,
Thanks for that solutions…it worked..thanks again
Now there is a second problem
application war file is deployed in weblogic, where the database connection string is in the war file itself and not comfigured in weblogic server level. everything is working fine. However the problem is that when the connections are established and then closed we get to see the inactive threads (inactive jdbc thin client)collected at database level. And in 20 mins more than 200 threads gets accumulated. We are of the impression that we cannot do anything from weblogic application server level because the connection string is inside the war file and we never configured the database connection string at weblogic server level. please suggest a solution to kills those inactive threads at database level.

Hi middleware team,
Last week i came up with new problem in weblogic,
In my weblogic console,My managed server status is unknown but i was able to access the application deployed on it.
I just restarted my admin server and managed servers,everything back to normal.
just want to ask,Y did the managed server status automatically turned into unknown.
Thanks in advance

March 14th, 2011 on 10:05 pm
Hi Fabian,
Many times it happens that the AdminServer Loses the contact from NodeManager or with the Managed Server…so in that case it is not able to get the current state of the Managed Server properly and shows the State as UNKNOWN. (It is possible that the Managed Server might be running properly without any issue)…So in such scenario we must check any kind of WARNING messages in Admin/NodeManager/Managed Server Log…As well as we must investigate if there is any kind of Network glitch occurred on the given time stamp.
In Some of the Older versions of WLS (not remember exact version right now) but may be in WLS9.2 and WLS10 similar BUG was found. Investigating this kind of issue is very tough because these kind of issues are very intermittent and occurs once in a couple of months…or more.

Hi Guys,
I am facing an issue with Unit Of Order feature of Weblogic.I have a distributed Queue(Q1) which sends message to another distributed Queue(Q2).Before sending messages to Q2,I set unitofOrder property to my wlMessageProducer and send the message.
Everthing works in a single managed server.But when It is deployed in a clustered Env, and when we send in messages 1) all the messages are only processed by ManagesServer1’s Q1
2) If any messages made in to managedServer2′ Q1,all those messages fail to write to Q2 on either of the server;they fail with the following exception :
“weblogic.jms.extensions.JMSOrderException: hashed member of jms!Queue2 is jms!JMSServer001@Queue2 which is not available”
I checked both the managed servers and they were running.
These are the steps I followed while configuring the UOO on my distribyuted Queue :
Created a distributed Queue1,left the default values on it.
While sending the messages to the Queue2,I used WlMessageProducer to send messages and I did set the property called setUnitofOrder(passed a String).
On the connection Factory setting unchecked the Server Affinity Enabled.(for load balancing)
Is their any additional setting I need to make or which I might be missing.
Thanks

I have a windows machine (windows XP),and using putty I am trying to assess that Linux server (using putty-ssh), I am able to connect and do all kinds of operations.
I am not able to “telnet.
I am able to start the remote server using putty. But I am not able to see weblogic admin console from windows machine. I am not seeing any error at logs.Please help me.
Thanks a lot
Viswa
March 21st, 2011 on 5:06 pm
Hi Viswa,
If your Windows box is configured for telnet and if the telnet is enabled on your Linux 5.2 Box Still if you are not able to telnet the Linux5.2 box …Means Either the WLS Server is not listening on the port which you mentioned in the Telnet command….Or the WebLogic is listening to a Separate IP Address….(Check the config.xml to get the correct <listen-address>)
If the above case is not correct then it means the N/W in whcih your Linux5.2 Box is running is not allowing some communication from your Windows-XP box via some specific ports. So please make sure that there is no Firewall issue b/w your Windows N/W and Linux5.2 N/W.
The simplest way to test it In your WINDOWS box open a Command prompt then run “setWLSEnv.cmd” then run the following PING command provided by weblogic:
If Http Tunneling is enable on your AdminServer to listen to HTTP protocol then run the below command:
java weblogic.Admin -url http://xxxx:7001 -username weblogic -password weblogic PING
If Http Tunneling is NOT enable on your AdminServer to listen to HTTP protocol then run the below command:
java weblogic.Admin -url t3://hostName:7001 -username weblogic -password weblogic PING
If you don’t get any PING reply from WebLogic …then you need to contact your N/W Administrators.

Thanks for the quick reply,”for y managed server status automatically turned into unknown status”.Actually wanted to give a detailed explanation to the client out here.
Last week i faced a new issue and till it on,ie
I had deployed a application on a new managed server,port 80 and ssl default port 443.
my application was working fine with
https://
now i just wanted a redirection operation
ie when ever the end user user uses
http://,he should be redirected to https://.I was trying to convenience my client ie i will completely block the access to http by just changing the port of managed server but he was ot agreeing with it.
Is this possible??or any work around will be surely helpful
Thanks in advance

Any help is much appreciated.
March 31st, 2011 on 5:54 pm
Hi Munnad,
I need one clarification here what is “Console IP”… As you mentioned that as soon as a column value of your database table changes then then you want to show alert to console(IP).{IP can be retrieved from db as it is configured in db.}
Please let us know what is this console IP is it the weblogic admin console you are talking about?

hi Middle ware team,
Right now,Facing a new problem..
Is this possible?
1)This is a production environment,so i cant take a down time..I have deployed a war file Managed server1 and now im given a new war file(minor changes of the prev war file which is already been deployed on Managed server 1) which needs to deployed,So i deployed the war file on Managed server 2.Can i automatically redirect the user internally to access this new deployment.I mean,If the user is given http://:7002/xyz(this is the managed server 1),it should automatically redirect to http://:7003/xyz..In this way,i dont need to take a down time.
Will replication solve ma problem

Everything is working fine.
Problem is my client wants me to start weblogic as a windows service to prevent any possible closing of the start scripts.
I am not sure we can run the StartWeblogic.cmd in the background like we usually do in Linux.
How do we take care of passing those parameters i.e. username and password.
Any inputs is really appreciated.

Thank you for the input. Really appreciate.
However, after much rnd on the net, I somewhat follow the same idealogy as below.. i.e. the script I build.
echo off
SETLOCAL
set DOMAIN_NAME=syncro_domain
set USERDOMAIN_HOME=D:bea_homewlserver_10.0.2user_projectsdomainssyncro_domain
set SERVER_NAME=AdminServer
set WLS_USER=weblogic
set WLS_PW=something@else1
set PRODUCTION_MODE=true
set JAVA_VENDOR=Sun
set JAVA_HOME=C:Program FilesJavajrockit-jdk1.6.0_22-R28.1.1-4.0.1
set MEM_ARGS=-Xms1024m -Xmx1024m
set ADMIN_URL=http://10.20.10.96:7001
call “D:bea_homewlserver_10.0.2wlserver_10.0serverbininstallSvc.cmd”
ENDLOCAL
…
How ever I encounter the following error when I tried to start the service from services.msc panel.
Could not start the beasvc syncro_domain_AdminServer service on Local Computer
System error 1075 has occurred.
The dependency service does not exist or has been marked for deletion.

Hi Andrew,
Few things here:
1). You need not to set “set ADMIN_URL=http://10.20.10.96:7001” in above script because we can see that you are trying to start AdminServer as Windows Service. And for AdminServer you need not to have the ADMIN_URL property….So please remove it from your Script.
2). Also please make sure that there is no Special Non-printable characters should not be there inside the script. Even the Trailing Space Characters at the end of above lines may cause windows Service failure.
3). The most surprising thing i can see is following:
set JAVA_VENDOR=Sun
set JAVA_HOME=C:Program FilesJavajrockit-jdk1.6.0_22-R28.1.1-4.0.1
Because if you want to use JRockit JVM then the JAVA_VENDOR must be “BEA” (Not Sun)

Hi Andrew,
I have just emailed you few windows service scripts which would surely work at your end and have added few flags which would also help in debugging any issue in future.
The reason I emailed you is because I had to attach you the scripts, however if you have any technical issues please free to get in touch with us using comments only.

Please suggest here ASAP,
Have configured all Nodes in my Domain as follows:
If more than 2 Stuck threads are Observed on a particular Node, then Consider that Node as Failed.
So that user wont experience ERROR 404…..
Please suggest on the above mentioned Configuration.
Thanks
Sathya
April 10th, 2011 on 1:02 pm
Hi Sathya,
First of all I dont think this can be done and if some how you are able to achieve this then too the clients would get 404 error as the request gone to that server would not able to send the response back to the server.
The options to avoid 404 error to your client is that make sure you have looked to every aspect which can cause a stuck threads or make it busy so that it cannot response the request now that is a pretty hard job to do and lot of testing has to be performed on that servers and after too it is not assured that this server would not go down.

Hi MiddlewareMagic team,
Actually i was doing some testing and ended up getting lost.Problem is,i was wanted to find the ip address of the user who are gettin logged in into my application so i just added this component “cp-i ” in Extended Logging Format Fields in server–>loggin–>http,This is working fine in Production environment but wen i tried the same in test environment i m not gettin it..My acces logs are above 8 kb.
When I check my access logs(through console as well as server/logs)..I get only Message column.Tried to customise the table but im not getting anything under Column Display Available: and under Chosen: i can see only message.I might have checked or unchecked check box’s,i guess.
Thanks for your help.Feeling bad for posting for such minor issues.
Regards

April 18th, 2011 on 6:32 pm
Hi Fabian,
By default the access log buffer size is 8 KB so until that 8KB data is not filled in the buffer no entry is written in the “access.log” file so you may not be able to see anything. Just try to decrease the accesslog buffer size to 0 KB and then try:…… In your production environment May be due to excessive requests the logs gets written very fast compared to Development environment logs.
– The LogFileMBean now includes a buffer-size-kb parameter.
– This parameter has a default value of 8 KB hence it waits for the 8 KB and then starts writing in the access.log
– When set to zero, it will not buffer the log messages and starts writting in the access.log
For example, to set the buffer size for access.log in config.xml:
… 0
OR
You can use “-Dweblogic.logging.bufferSizeKB=0” at the time of starting the server.

How do i identify how much Max and Min memory has to be given to a web application.
Say if I have a application “A” to be on boarded to my WL, How much heap is required can be identified on what basis?
Thanks
Sathya
April 19th, 2011 on 12:03 am
Memory is not allocated application wise. So you cannot calculate how much memory is being consumed by Application “A” and how much memory is being consumed by Application “B”.
Load testing and a Good performance testing team is needed for calculating the required machine.
There is no standard formula.

Hi Jay,
Thanks for your previous solution it worked well.
I Have made my weblogic application server to run automatically whenever the server boots up..ie kept it in ma server start scripts..using nohup command
Is This possible ie Once my Admin server is up and even my nodemanager is up,to start managed server automatically…I have only one domain..
In current scenario,I have to manually select each n ever managed server and den press start.

Hi Middleware Team,
Stuck in a serious problem rite now.
My log files are increasing tremendously..ie in a day It shoots upto 1 gb..(every 5 mins a new log file is written renamin the previous one which reaches 5 mb).There are not too many users.Just 200-250 total sessions in a day..Checked the log files,im just getting this msg every sec
MS_7003 [ACTIVE] ExecuteThread: ’18’ for queue: ‘weblogic.kernel.Default (self-tuning)’ <>.
I have to clear the log files continuously ie after every 3-4hrs.
The same configuration is on another weblogic server and there log files doesnt increase to that extent..Y is this happening..
Thanks in advance

Hi Fabian,
We are not able to see what messages are repeatedly getting logged in the Server.log which is consuming more disk space, So please post the Snippet of Server log messages which are repeatedly getting logged and filling the server log Like described here: http://middlewaremagic.com/weblogic/wp-content/uploads/2009/08/How_to_Post_Comments.jpg . Make sure that the Server Debugs are off or only the required Debug flags are switched ON.
Also you can use the following kind of Shell Script as a Cron JOB to nullify the current Server.log without interrupting the WebLogic. http://middlewaremagic.com/weblogic/?page_id=241#comment-3534

Admin server as well uses the same setDomainEnv.cmd file, Right?

Hi Sathya,
Root cause of the error was : Caused by: java.lang.ClassNotFoundException: oracle.dms.wls.DMSServletFilter
It’s simple logic that this class is not present in the CLASSPATH of the Server or it’s not present inside the application other wise WLS Will never complaint about this class is missing. That could be an issue with the classloader configuration changes as well….
So adding this Jar explicitly in the CLASSPATH of the server will force server to load this jar at any cost. The same thing worked there as well.

Hi Middleware Magic Team,
Strange issue,My application which was deployed on production was running smoothly from past 1-2 months,Day before yesterday,i just restarted the entire weblogic server.Now i getting performance issue ie slowness.
I checked whether any threads are stuck(Server–>Monitoring–>threads) which might be causing the problem but none of the thread were stuck..
Checked the cpu and memory usage 0.1 and 5.8 respectively..
I m getting a throughput 17-22 while previously i used to get around 0.5 – 2.from where should i start trouble shooting,Any specific area.
I have 1 more doubt,this same application is deployed on test and production.
On test,I get
Active Execute Threads -8
Execute Thread Total Count -9
But on production i have
Active Execute Threads -20
Execute Thread Total Count -20
Active Execute Threads should be same rite on production as well as test,Since both the application are same.
Y is this so?
Thanks in advance

What I can make it out from your description is that the load to the application might been increased hence you are seeing this issue. Which WLS version are you using and after restart are you seeing the same behavior everyday or just that one day?

In Jrockit Thread Dump.. I see blocked State(Fat lock) and (thin lock) .. whats the difference between Fat lock and Thin Lock…
Thanks
Sathya
May 2nd, 2011 on 7:05 pm
Hi Sathya,
Fat locks:
A fat lock is a lock with a history of contention (several threads trying to take the lock simultaneously), or a lock that has been waited on (for notification).
Thin locks:
A thin lock is a lock that does not have any contention.

Now i don’t have 8.1 in my system.Let me know on this please.

However why do you have this types of curiosity, when you dont have WLS 8.1 with you. Also if you had it still the support for it has been closed and these days no one uses it (i.e. else should not use it).

Hi Fabian,
Good morning 🙂
So from the error it seems that the thread had taken more then 600 seconds (i.e. 718 seconds ) time to complete its work and from the stack it seems that the thread was try to read some data from the socket. This can be a network glitch as you said that it was working fine after some time, hence no worries about it. But if you see more similar issue then we would have to look into it.
For these kind of issue we had created a WLST script which would have a look on the stuck threads and would generate thread dumps during the issue occurs so that we would have some data to look into it. Check out the below link

May 9th, 2011 on 4:12 pm
Hi Apurva,
Here the following thing that we need to check.
1.) Try using “-file clientCert.cer”
rather than “.pem”
Then later take a back up and rename the file to der
and use the weblogic’s utility “java utils.der2pem ”
2.) try removing the -trustcacerts options. I believe that might work.
Let me know in which keystore u are importing TRUST or IDENTITY

Hello Admins,
Can u help me to understand about threads in weblogic? my question is this:
I did an app for JSE where i create some threads that made polling to a mysql database get some records and do logic stuff with that info.
I tried to recreate that app for weblogic but i read that no threads are allowed for JEE. So i use TimerService to start the logic at some time.
What i did is a good practice or should i uso some weblogic api to simulate threads sleep and awake?
I hope u can understand my question, thanx in advance for ur response.
Regards
Mauro 🙂
May 12th, 2011 on 10:28 pm
Hi Mauricio,
Not only WebLogic rather most of the best Application servers does not recommend/allow a deployed application to manage their own Application level Threads. This is because the requests are processed by the Application Server Threads like (Worker Threads) Execute Threads. The application processes clients request on a Multithreaded environment which is managed by the Application Servers … so These servers do not want any Application level thread interfare in their own JOB.
So Opening a Socket through an Application and Creating and Managing Application Level Threads are STRICTLY prohibited. So you have chosen the right and recommended way to achieve your goal using TimerService.

— Question about hogging threads —
–Environment —
Weblogic 10.3.2
Windows 2008 R2
JDK Sun 1.60_20
—————-
Hi all,
I’ve run this sunday a ‘stress test’on one of our application. The Weblogic node didn’t crash and dealed correctly the requests.
-However looking at the metrics, I can see that the Hogging thread count increased linearly up to 400; stayed at this value for 40 minutes then decrease linearly.
-The same behaviour was observed on the Thread Queue legth…
-looking at the log files, I can see plenty of threads marked as STUCK then marked unstuck…
My understanding is that too many requests are submitted to the my Weblogic.
Now, could anyone give me a clear definition of hogging thread? looking on the web, I’m more confused now
What are the actions we can take on Weblogic to reduce this hogging situation?
Thanks for your help and thanks for all your excellent posts
May 24th, 2011 on 6:27 pm
Hi Fipnova51,
Hogging threads:
Hogging threads can be called as a candidates for stuck threads in other words, those threads that “might” get stuck are called hogging threads. These threads will be declared as stuck threads after “StuckThreadMaxTimeout” seconds which by default value is 600secs.
You can also get the more information and Alerts when hogging threads have reached at the defined level from the below links

Hi Ravish,
Thanks for your links. I’ll have a look at them.
Noe reading “Performance and tuning for Oracle Weblogic Server”, I noticed that the max TotalThreadCount is set to 400.
I’ve been looking in the admin console and config.xml file but couldn’t see any references to this value.
Do you know if it’s possible to change it?
Thanks
May 26th, 2011 on 5:38 pm
Hi Fipnova51,
MaxThreadCount is by default set to 400 By weblogic. But if you want to change it then you can use the JAVA_OPTIONS in your servers startScript
-Dweblogic.threadpool.MinPoolSize=400
-Dweblogic.threadpool.MaxPoolSize=500

Hi MiddlewareMagic team,
I have another question.
The place I’m working at as a team deditaed to middleware solutions. In my case they’re in charge to create Weblogic domain when needed.
My weblogic domain runs on Windows and managed servers are started through beasvc64.exe
Looking at the registry, I modified the Cmdline entry to add “verbose:gc -loggc” arguments. Therefore all my GC are saved in a file.
My problem is if I restarted my managed server, my loggc file is overwritten during the restart and I lost my metrics.
I modified my loggc file by adding %DATE% args (onsole1_%DATE:~10,4%%DATE:~7,2%%DATE:~4,2%_%TIME:~0,2%%TIME:~3,2%%TIME:~6,2%.log) unfortunately it didn’t create any file.
How can I make sure my loggc file isn’t overwritten when a restart is initiated?
Thanks for your advices.
May 28th, 2011 on 6:52 pm
Hi fipnova51,
First of all I dont think so it is recommended to modify anything is the Windows registry, so try to again reinstall your Windows Service for Managed server with adding the below line in script and then try it out if that works for you
set JAVA_OPTIONS= -verbose:gc -loggc -Dweblogic.Stdout=D:bea_homewlserver_10.0.2user_projectsdomainssyncro_domainASstdout.txt -Dweblogic.Stderr=D:bea_homewlserver_10.0.2user_projectsdomainssyncro_domainASstderr.txt

June 16th, 2011 on 6:18 pm
Hi Joe,
As you have mentioned that very frequently you are facing OutOfMemory Eror in your WebLogic Server. So can you plesae let us know which kind of OutOfMemory is it Like OutOfMemory in HeapSpace, OutOfMemory In native Space, OutOfMemory in PermGen Space..
Also we would require the gc log to see if the Garbage Collection is happening properly or not?
If based on GC log report if we will find that Garbage Collection is happening properly on time and Full Garbage Collection pause is not taking more than 6-8 Seconds then Garbage Collection is good for 2 GB Heap space as for 2GB Heap space 6-8 Seconds of Full GC pause is normal…. But if it takes more than that then it means there could some problem with the Garbage Collection as well.
Suppose if the Garbage Collection is happening properly then in that case we must collect the Heap Dump at the Peak Heap Utilization of Heap space… as some time -XX:+HeapDumpOnOutOfMemoryError JAVA_OPTION is not able to generate the Heap Dumps so in that case we will have to collect the heap dump manually (At the peak Heap Utilization)
To Know about OutOfMemory issues :

OS: RedHat Enterprise Linux 5 – 32bit
WLS: 10.3.3
JDK: jrockit_160_05_R27.6.2-20 , Xms1024 Xmx1024
Topic: Garbage Collection
We recently upgraded from WebLogic 8.1 to WebLogic 11g 10.3.3. In doing so we ran into some difficulty applying garbage collection the way we used to.
In 8.1 we were able to use some regular expressions in the startup arguments to add date and time stamps for GC logging.
-Xverbose:memory,gc,gcpause,gcreport,memdbg -Xverbosetimestamp -Xverboselog:appServer-01-a/appServer-01-a-memory-gc-“$(date +%Y%m%d-%H%M%S)”
In 11g there seems to be an issue with this. It doesn’t single or double quotes, and seems to error on startup without them.
We’re resorted to running a cron job every night to roll the GC logs where this used to happen automatically whenever the managed server was restarted.
Do you have any suggestions on tuning garbage collection with WebLogic?
June 17th, 2011 on 2:38 pm
Hi Chris,
I tried the following and it worked:
export DATE=`date +%Y%m%d-%H%M%S`
JAVA_OPTIONS=”$JAVA_OPTIONS -Xverbose:memory,gc,gcpause,gcreport,memdbg -Xverbosetimestamp -Xverboselog:gc_${DATE}.log”
Please try the same and let us know. I could see that a gc log file created with name “gc_20110617-143342.log”

How can we know that max memory(heap) utilization on JVM in a day?
Thnx in Advance
Venu.

Hi Pyatla,
If you want to see the Whole days Heap Utilization then it will be best if you can enable the garbage Collection Logging. Once you get the garbage collection Log then you can just open it inside the “gcViewer” tool (http://www.tagtraum.com/gcviewer.html)to see a complete graph with time to findout at what time in a day the heap utilization was higher and what time it was normal.
Also to get a summary of Peak Heap Utilization and Garbage Collection statistics you can refer to the following article:
http://middlewaremagic.com/weblogic/?p=5131
For JVM tuning best practices you can also refer to the following article:

Thanks Jay.
Are you indicating the ‘export’ can be included in the WebLogic console’s Server Start arguments field?
June 21st, 2011 on 8:53 pm
Hi Chris,
I am sorry !!! looks like i misunderstood your issue.
As earlier you didn’t mention that you are trying to achieve the same using WebLogic Admin Console “Server State” tab. I am not sure if that can be done..I even don’t see any possibility to do that any more.
I tried to put the JAVA_OPTION in the server’s startScript “startWebLogic.sh”.

Hi Jay,
It’s odd. Our PreProduction environment has this working on the Admin Server, but I can’t seem to get it to work anywhere else.
Works on PreProduction Admin:
[ sourcecode language=”java” wraplines=”false” ]
-Xverbose:memory,gc,gcpause,gcreport,memdbg -Xverboselog:/opt/Oracle/Middleware/user_projects/domains/wlgPPDomain/servers/AdminServer/logs/AdminServer-memory-gc-$(date +%Y%m%d-%H%M%S).log
[ /sourcecode ]
Doesn’t work in Production:
[ sourcecode language=”java” wraplines=”false” ]
-Xverbose:memory,gc,gcpause,gcreport,memdbg -Xverboselog:/opt/Oracle/Middleware/user_projects/domains/wlgPRDDomain/servers/AdminServer/logs/AdminServer-memory-gc-$(date +%Y%m%d-%H%M%S).log
[ /sourcecode ]
I’ve been unable to detect any differences in the environments. PreProd doesn’t set a JAVA_OPTION value for date, nor does Production. Both show an empty value whenever I $echo $date or $DATE on the command line.
There’s nothing in the .bashrc or other user profile files on the Linux side of things either.
The same configuration in WebLogic exists between the two environments. The only exception is a two character difference in the filepath for the domain home.
We record garbage collection logs for all of our managed servers. In WLS 8.1 we used similar expressions to set the GC log file name. It worked fine. In WLS 11g 10.3.3 this doesn’t seem to work, and no amount of tweaking has seemed to help.
As a result a file which should show up as: “AdminServer-memory-gc-20110622-102133.log” instead shows as: “AdminServer-memory-gc-$(date”.
Any further ideas will be entertained.

Hi Joe,
Looks like your application deployment is internally using some DataSource by looking at the following line of StackTrace:
com.bea.console.actions.jdbc.datasources.createjdbcdatasource.CreateJDBCDataSource.selectTargets(CreateJDBCDataSource.java:558) at
So please make sure that the DataSource is created properly and targeted to the Cluster. It will be good if you can test the DataSource first if it is working fine or not. It will be good to look at the “Target”: of the DataSource is set to the Cluster properly or not as well.

Dear Middleware Team,
I had a doubt…Since my client had this requirement.
Is this possible??
Whenever,i want to shutdown the weblogic server for maintaince activity..I just want the weblogic users to get a pop up..”please log out after 10mins”..is this possible??
Current out netwark ppl are doing it..But this msg gets displayed to all the user,evn those users who are not using weblogic.
Please help.
Regards
Fabian
June 29th, 2011 on 6:57 pm
Hi Fabian,
Yes, this can be done. Your network guys are already giving the pop-up’s but only difficulty which you guys are facing is that you do not know who all are using weblogic. So to solve this issue you can refer to the below article which would help you do so.
Topic: HttpSession Monitoring using
http://middlewaremagic.com/weblogic/?p=1610
You would have to get the IP addresses of the client/user by replacing line-09 of Setp-3 by the following
BEFORE
session.setAttribute(“MyMainSessionAttribute”,userName);
AFTER:
String client_IP= request.getHeader(“X-Forwarded-For”);
session.setAttribute(“MyMainSessionAttribute”,client_IP);
The above code would fetch the IP address of the users and as explained in the post from the console you would get the list of users IP which can be shared by the network team, so now they would send that pop-up messages to these guys only who are using weblogic.

Hi All,
Am currently running Oracle Flex-cube in HP UX and for the past few months I have been facing serious speed issues and system hanging .I am new to weblogic and I kindly request for your assistance is setting up the best garbage collection parameter for this transactional based application. I have enough memory i.e 60Gb but still the problem is as if am running the application on a P1 machine.Please please assist.
July 6th, 2011 on 4:42 pm
Hi Joe,
For slow responsiveness of a Server there could be many factory involved like the
1) . Garbage Collection might not be happening properly, Means the Full GC pause might be very high.
2). The Heap Size might be set to too low compared to the application need.
3). The Most important thing is there might be some STUCK Threads in the Thread dumps.
So to find out the exact cause we need to do the following :
1). Use the Garbage Cat tool to generate the Garbage Collection Summary Report to see if the Garbage Collection is happening properly or not. Please refer to the article: http://middlewaremagic.com/weblogic/?p=5131
2). To Check Heap Utilization we need to again see the Garbage Collection Logs “Max Heap Space” And “Max Heap Occupancy” values…if these values are too close and If the Max Pause is average then it means the application requires more Heap Memory.
3). We need to collect the Heap Dump and need to look into it to see if there is any STUCK thread present or If any of the Thread is Causing High CPU utilization: http://middlewaremagic.com/weblogic/?p=4884

Hi All,
I am facing issues while migrating my application from OC4J to Weblogic 10.3.2.0.
weblogic.servlet.jsp.CompilationException: Failed to compile JSP /search.jsp search.jsp:2:18: Error in “initialize.jsp” at line 99: The method getServletContext() is undefined for the type __search ————– search.jsp:2:18: Error in “initialize.jsp” at line 103: The method getServletContext() is undefined for the type __search
I have tried adding the servlet jars to the lib folder of WEB-INF.
I tried changing the getServletContext() to application.
But I am unable to understand what is the issue for the jsp compilation error here for the implicit objects which are being used within the jspInit call within initialize.jsp file.
Any help on this will be greatly appreciated.
Thank you,
Richa Kamal.
July 11th, 2011 on 10:24 pm
Hi Richa,
We will have to look inside the search.jsp page to know what exactly is happening there in line number 2 of the JSP Page Column number 18.
Will it be possible for you to share the search.jsp with us so that we can check if any thing needs to be changed there?
You can even post us your JSP page in the following E-Mail address “contact@middlewaremagic.com” As it is very difficult to comment anything without looking at the JSP page.

Hi Team,
Over the past few weeks, we have noticed that whenever we deploy any new version in Web-Logic 10.3.3, the changes don’t reflect. The only option through which the changes would reflect is to delete the contents of the stage and Temp folder in each managed server and then do a fresh deployment.
—How can we avoid this deleting process, as managed server count is high in number and CR window time will be less in Production.
— How could I configure WebLogic to delete them automatically (rather than writing a cron job or some external process that would periodically remove them).
Thanks for your help,
Sunny
July 12th, 2011 on 9:47 am
Hi Sunny,
As you have mentioned that you have a large number of Managed Servers in your Production environment … So please let us know How you are deploying a fresh Version of your Application on it ? Are you using any WLST/JMX/weblogic.Deployer Script ?
Because once we know how you are deploying your applications currently then only we will be able to find some strings to comment… If you are not already using WLST kind of utility to undeploy and deploy all your applications at once to all the Managed Servers then we can provide you a WLST script which will do all these things at once. You will need to just invoke the WLST Script to Undeploy the previous versions of your Application and then deploy a New Version of your application on the targeted Servers.

I was able to resolve the “The method getServletContext() is undefined for the type __search error” by changing a bit of code.
In WLS, getServletContext() and implicit objects like application,config are not recognized within the jspinit call.So we need to use getServletConfig().getServletContext() instead of the
application or getServletContext().

Hi Team,
A user getting below error while accesing forms application

This may be the result of a network error,or a failure on the server.
you will need to reestablish your session..
No other users are not affected,but if the same user close error window & if he opens the same application again he can connect.
new user connection are allowed after this occurs.
can you help me how to resolve this problem?

Hi Apurva,
The Root cause of “oracle.ldap.oidinstall.backend.OIDCAException” exception is “java.sql.SQLException: Io exception: The Network Adapter could not establish the connection”.
Looks like your Internet Directory configuration assistant requires a Oracle Database connectivity and when it is trying to connect to Oracle Database at that time due to the N/W issue it is not able to connect to the Database.
So please check first whether your Database is UP and running or now (Is it opening the database listen port or not) ?
There are some more debugging steps mentione din the following link regarding “http://middlewaremagic.com/weblogic/?p=2477” issue “Common Jdbc Issues-1). The Network Adapter could not establish the connection”

Hi, I just want to see if anyone has run into a similar problem before.
I have a customer that will be runnning my application on weblogic server 10.3.4.
They have set their domain up in production mode on RHEL5 under a weblogic user. I have done this many times myself without issue. However the customer is having problems with logging.
Most of the logs end up in the proper place on the file system, but some app specific logs are missing. Unfortunatly, the logging strategy I’m stuck with in this case is system.out.println.
I know something is wrong with their logging because when I try to view the Server logs via the console, nothing is there. I’ve never seen that empty before. I’ve asked them to check all file level permissions and they insist everything is “fine”.
Have any of you run into something like this before? Could it be an selinux thing that we’re missing? Any thought idea’s or anything would be very helpful.
Thanks,
Kevin
August 5th, 2011 on 11:23 am
Hi Kevin,
Point-1).
If you are seeing that the “System.out.println” statement outputs are not getting printed to the Server logs then please do the following:
If you want to redirect the STDOUT file of your Server as well inside the Server Log then u can add the following Flag as well in the JAVA_OPTIONS:
-Dweblogic.log.RedirectStdoutToServerLogEnabled=true
Point-2). As you have mentined that you are not able to see the server Logs from the admin-console , So in order to find out what is wrong with the server logging please do the following to see whether the server.log is getting populated properly or not?
If your Server is running in “PRODUCTION MODE” then you must use the SSL Protocol to access the Logs using weblogic.Admin Utility. like following, Means you will have to use the following command with “-Dweblogic.security.TrustKeyStore=DemoTrust” JAVA_OPTION to access the Logs (NOTE: Please pass the correct TrustKeyStore in your command … If you are using anything else apart from the default one.):
java -Dweblogic.security.TrustKeyStore=DemoTrust weblogic.Admin -url t3s://localhost:4002 -username weblogic -password weblogic SERVERLOG
If above command gives you server.log entries then it means that the server.log is getting populated as expected.
Additionally it will be good if you can try changing the “server.log” directory from the admin-console to some other directory to see if the logging is happening fine or not?
Point-3). As you have mentioned that some Application level logs are missing … So basically WebLogic does not controls the Application level logging rather the application level logging frameworks like log4j are actually responsible for rotating and managing the application level logs which need to be checked from the application side.

Hi Praveen,
The StackOverFlowError is a kind of OutOfMemory error in JVMs native area which is occurred when the Thread Stack Size grows more then expected. So we must keep in mind that the Thread Stack Size is set properly. The Thread Stack Size can be set using the JAVA_OPTION -Xss. Setting very small StackSize (-Xss) causes . StackSize is a memory area which is allocated to individual threads where they can place their thread local objects/variables.
Some times we get this error while performing a particular type of operation which requires the Thread do create more Thread Local Objects/Variables, For example if the Xss size is set to default or set to very less then while performing a particular operation in Admin Console might cause StackOverflow Error because the WebLogic Admin Console is a Portal based application and internally it uses a lots of temporary netuix components and page flows which can cause this error.
So we must be very careful regarding this kind of error and we should increase the -Xss size based on requirement.
NOTE: As you might be running your server for quite a long time and you never encountered this error before so it is obvious for you to ask Why suddenly you require to tune the Xss size ? It was working fine earlier and after restart of server as well it started working ….So why to tune the Xss?
It is because the error itself indicates that the Thread StackSize exceeded a certain limit and which is causing this issue. And many times we don’t perform a particular operation in a certain order …but some order of execution requires more Thread Local Objects / Variables which we might have not noticed earlier.

Hi Apurva,
This kind of error usually occurs due to unclean bounce of OPMN and whenever an unclean bounce happens pid values are not cleaned properly and try the following:
1. opmnctl stopall -p 389 (NON-SSL) / ldapbind -h -p 636 -U 1 -D cn=orcladmin -w (SSL)
2. clear all files under $ORACLE_HOME/opmn/logs & $ORACLE_HOME/opmn/logs/states and remove .opmndat (hidden file => to view issue ls -la )
3. Make sure no process holding any ports => run netstat -anop |grep LIST
4. Make sure this command does’t show anything => ps auxww |grep rmi
5. Make sure DB Listener and OID (Ldapbind) are successfull ….
a. tnsping
b. ldapbind -h
6. opmnctl startall
Also please refer to the following Links which has EXACTLY same Exception StaackTrace as yours:

Hi Middleware Admins,
We are working on solaris10 platform, Weblogic11g. I have a weird scenario. Basically we have a citrix server,Our Company(XY) servers(30), F5 load balancing. Here when users are entering through citrix servers the request is hitting to only 2 particular servers in our company among the 30servers present. This is happening only when users login through citrix, because of which the performance of these 2servers is very high and users are facing slowness. Initially we were expecting there might be a problem in our company servers, so we removed the 2servers out of service. Later all the request are now going to only other 2 servers among the 28 present servers. So why is the request not disrtibuted equally among all the 30 servers. Is there any place we need to check. We are unable to get proper information in the logs and moreover i just moved to this company initially so it will take time for me to get complete access and provide more info.Can you please suggest me anything for the above scenario and let me know if need to give more info.
Thanks,
Tom
August 17th, 2011 on 7:50 pm
I think you have to look at your load balancing. See how it is configured and how it detects the WebLogic servers.
Usually a load balancer uses some kind of round robin algorithm to the back-end servers.
Note that in the case of session binding, the requests by the same users are always send to the same server. In this case WebLogic sends a session cookie jsessionid to the client. In this session cookie a primary and a secondary server are present. This in order to replicate data only to one server in the cluster.
As mentioned above, a good starting point is to look at the load balancer.

Hi,
The weblogic domain is configured as,
machine-1 has admin and one managed server
machine-2 had other manged server
both managed servers form a cluster
For both machines, the admin console shows that the nodemanger is reachable.
But when i am not able to start the 2nd managed server from the console… (i can start it from command line though)
i see the following errors… related to boot identity..

Hi Raj,
I would suggest you to do have a look at the below article from Step-7 and make sure you have done the Step-8

Hi Giriraj,
Regarding the WARNING messages which you are seeing in your Logs for Invalid JAVA_OPTIONS …Please make sure that you are using Sun JDK… because the JAVA_OPTIONS which you are using -XX:MaxPermSize=256m -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseConcMarkSweepGC are specific to SUN JDK.
So if you will start your Server using JRockit JVM then you will receive the same Warning messages because JRockit JVM does not have these JAVA_OPTIONS.
Additionally if you see that the Nodemanager is reachable in the admin Console still it is not able to connect then Please check the Managed Server log of the same time stamp.

Thanks Guys…
Jay,
here is the error i see in the .out file…
I also tried to create new boot.properties file but it did not work….
the encrypted password in the boot.properties file is different for both machines… although user is same..
so i tried to create plain text file in machine 2 but somehow it gets encrypted diffferently than in machien 1
any thoughts??

Hi Giriraj,
I feel that your nmEnroll is not done properly…. So please make sure that you are following the Step7) and Step8). Mentioned by Ravish in the following comment:
http://middlewaremagic.com/weblogic/?page_id=2594&cpage=6#comment-4824
Still if the problem persists then please do the following :
Please Copy the “SerializedSystemIni.dat” file from “$DOMAIN_HOME/security” Location and Paste it inside “wlserver_10.3/common/nodemanager/security” (Means the NodeManager’s Security directory) Location. Then restart your NodeManager….

Hi Jay,
We are preparing the disaster recover details in oracle weblogic server.
1. The Oracle Application Server Disaster Recovery solution uses disk replication
technology for disaster protection of Oracle Application Server middle tier components.
2. Enterprise Deployments need protection from unforeseen disasters and
natural calamities. One protection solution involves setting up a standby site at a
geographically different location than the production site
3.The standby site may have equal or fewer services and resources compared to the production site.
4. Application data, metadata, configuration data, and security data are replicated to the standby site on a
periodic basis.
5. The standby site is normally in a passive mode; it is started when the production site is not available.
6. An Oracle Application Server Disaster Recovery configuration that is completely identical across tiers on the production site and standby site.
7. The production site and standby site have the identical number of hosts, load balancers, instances, and applications.
8. The same ports are used for both sites production & standby site.
In our disaster recovery method we are using the Asymmetric topology.
1. In an asymmetric topology, the standby site can use less hardware.
2. Example:- the standby site can use fewer Application Server instances
create mount points and links on the hosts to the Oracle home
directories on the shared storage where the Oracle Application Server instances will be installed
These datas are enough for disaster recover for oracle weblogic server.
Availble only Oracle WebLogic Server 9.2 MP3 to 10.3

Hi,
I have a doubt.
How to set Time outs for inactive session.
If i go to Deployment–>configuration tab–>Session Timeout (in seconds)=3600
which states that “The amount of time (in seconds) that a session can remain inactive before it is invalidated”.
There is one more parameter in datasource–>configuration–>connection pool–>Inactive Connection Timeout:0
Right now im confused which parameter to set or is there any other parameter for weblogic
I have created connection pooling there are 300 active sessions but there are 900-1000 total session created in weblogic
There are lot(1500-2000) of inactive jdbc connections created at databse end and those inactive jdbc connections are increasing continuously
we undeploy the application still inactive jdbc connections are created at database end.
plz help me how to reduced inactive jdbc connections which are continuously increasing
is there any more parameter which we need to tune according to conenction-pool values(Initial capacity:max capacity)
plz help

Above is actually HttpSession timeout (NOT related to the Jdbc Connection timeout.)
Datasource–>configuration–>connection pool–>Inactive Connection
When you set a value for Inactive Connection Timeout, WebLogic Server will forcibly return a connection to the data source when there is no activity on a reserved connection for the number of seconds that you specify. When set to 0 (the default value), this feature is turned off.
A leaked connection is a connection that was not properly returned to the connection pool in the data source. To automatically recover leaked connections, you can specify a value for Inactive Connection Timeout on the JDBC Data Source.
But even after setting the “Inactive Connection timeout” to some value if you are seeing the same behavior then please try to use the “Latest Jdbc Driver” and also contact your Database administrators because many times the Database do not close the open cursors properly. As i don’t think any further tuning is required from WebLogic side.

Hi Apurva,
Oracle Thin Driver would just work fine.
