Hello Jay, i wondered if it is possible to you to make a tutorial about jdbc pool connections.
I made a little program with a connection to oracle database using ibatis, but i dont know if i need to make a configuration inside weblogic console administration (using WLS 10.0 MP2). In fact i dont know much about connection pools in weblogic 🙁
It would be very helpful if u teach this thing with an example of a EJB 3.0 doing the connection.
Thanx in advance Jay, and i hope this isnt a problem to you.
Best Regard

Hi Mgaldames,
To Create a DataSource for Clustered Environment is not different from creating a DataSource and targetting it to a Single Server. All what u need to do is….Create any DataSource and finally Target it to a Cluster rather than Targetting it to a Single Server. Data Source Lookup code wise u need not to make any additional changes. Just u need to write the following Code while performing the Look up of DataSource from Client end…
import java.rmi.*;
import javax.naming.*;
import java.util.*;
import javax.sql.*;
import java.sql.*;
public class LookupDataSource
{
public final static String JNDI_FACTORY = “weblogic.jndi.WLInitialContextFactory”;
private static String clusterUrl =”t3://localhost:7003,localhost:7005,localhost:7007″;
//The Aboe URL should point to all the Managed Servers URL Which are part of the Cluster….
//Usually Cluster address means the comma Separated URL list of all the ManagedServers which are part of clusters…
public static void main(String ar[])throws Exception
{
InitialContext ic=null;
try{
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY);
env.put(Context.PROVIDER_URL, clusterUrl);
env.put(Context.SECURITY_PRINCIPAL,”weblogic”);
env.put(Context.SECURITY_CREDENTIALS,”weblogic”);
ic = new InitialContext(env);
}
catch(Exception e){
System.out.println(“nnt Unable To Get The InitialContext => “+e);
}
try{
DataSource ds=(DataSource)ic.lookup(“YourDataSourceJNDIName”);
System.out.println(“t Got the DataSource… “+ds);
}
catch(Exception e)
{
System.out.println(“nnt Unable To Get DataSource => “+e);
e.printStackTrace();
}
}
}
——————–
Regarding Threading Concepts….
We should never try to Create our own Threads inside the EJB/Servlet kind of applications…because The Application Server Container assigns a new Thread for every request processing…once the request processing gets finished…it assigns the same thread to some other clients request…So if we will implement our own Thread implementation inside EJBs/Servlets then in that case with a small mistake in the Code the Thread created by us may take a longer duration to execute …until that time the parent thread might have completed its Task and Might have assigned to some other clients request…Like this our Threads will remain running inside the container.
Apart from this…Many informations like Transactions and Application Context related informations are passed by the Containers via their own Threads…to the other components. So we should never create our Own Threads while working with Servlets and EJBs.

Thanx again for the reply Jay, i am learning a lot 🙂
I have a question, and it would be great if u can help me with this:
1) i used to read a MQ Series queue from a simple java application using mq series api and a thread to listen to that queue. Now i want to do the same in a EJB 3.0 but u suggest to not use thread. Can u suggest me a way to do the same? (i thought in the possibility of using application life cycle listener)
Thanx in advance!
July 16th, 2010 on 10:07 am
Hi Mauro,
It is not recommended to create our own Thread inside WebLogic Container to perform application specific activity. Because Thread Handling part should be taken care by the Container itself.
I understand your requirement …u want an application deployed on WebLogic Server which should be able to get JMS Messages from the MQ-Series… in order to achieve the best and recommended way is creating “Foreign JMS Server” and then configure it to connect to the MQ Series messages…then u can deploy a Simple MDB application inside your WebLogic Server to read the Messages from that Foreigh JMS Server.
Some usefull link u will find here:
Please refer to the Below Link to achieve this….With Screenshots as well
Suitable for WLS8.x
http://www.ibm.com/developerworks/websphere/library/techarticles/0604_kesavan/0604_kesavan.html
For later versions of WLS8.x you can even refer to :
http://ibswings.blogspot.com/2008/02/integrating-mq-broker-6-with-bea.html
Means u need to create a Message Bridge between WebLogic and MQ Series…something similar to (Not exactly same because the link demonstrates Message Bridge configuration B/w WebLogic Domain to another WebLogic Domain) : http://middlewaremagic.com/weblogic/2010/06/22/configuring-message-bridge-between-two-weblogic-server-domains-using-wlst/
Apart from this Please refer to : http://download.oracle.com/docs/cd/E11035_01/wls100/bridge/basics.html#wp1162799 The above Link Tells about What is Messaging Bridge And Why/When to use it?

thanks
venu
August 2nd, 2010 on 11:14 pm
Hi Venu,
In that case it will follow the setting provided as part of AdminConsole—>Server–>Logging (Tab) Out file settings. Otherwise there wont be any File. Rather all the stdout informations will go in the Command prompt in which you started the WebLogic Server (In Windows). In windows you can use the redirection operator to redirect the outout to a separate file like:
startWebLogic.cmd > MyOutfile.txt
If you are using Unix Based OS then you can use “nohup” to redirect the output of your file in the Nohup out file.
nohup startWebLogic.sh 2>&1> nohup.out
Here 2>&1 represents that send all the Stdout as well as all StdErr messages in the same file “nohup.out”

thnx in advnce
venu
August 3rd, 2010 on 10:37 pm
Hi Venu,
No If the AdminServer fails …Nodemanager will not restart the ManagedServer. Managed Servers will keep on runnning….
Next time if Admin is down and if you will try to start/restart Managed Servers using NodeManager then they will use the “msi-config.xml” file to boot up.

Hi jay ,
sometimes when i am working on production deployment , some applications is going to admin state instead of retired state . What is this admin state.and i observe some times when i restarting the manged servers , it went to admin state instead of running state, i click on resume after that it will work good , and the state is in running state.
when the deployment is in admin state we can not do anything , we cannot delete that application , we can not stop that application , why and what is this admin state means really?
August 19th, 2010 on 11:27 am
Hi Rocky,
There is no hard Rule that Why a Server or An Application Goes into the Admin Mode. But in 90 % cases you will find that some of the System Resources like JDBC/JMS/Application resources are not getting activated properly which causes the Server/Application to Move into the AdminState.
To Identify the root cause of these kind of issues we need to set the Server Logging Level to Trace and need to keenly analyze the Complete Server Log …and WARNNING need to be keenly observed. Still if we dont find anything then we to Apply Application Level Debug Flags or Cluster Cmmunication related Debug Flags….based on our Assumptions.

Hi Jay
How to set environment variable in weblogic server ??
Rcently i’ve created one new domain , and the user complaints to me that he’s not able to access the app – and he sees the error like
java.lang.NoClassDefFoundError: com/csc/mailservice/client/MailServiceClient
And he suggested like environment variable was setup , so asking me to setup.
Where can i do this ??
Please help me?
Thanks.
August 24th, 2010 on 5:54 pm
Hi Arun,
The “java.lang.NoClassDefFoundError: com/csc/mailservice/client/MailServiceClient” Indicates that the Class is Not present in the CLASSPATH. As it looks like that “com/csc/mailservice/client/MailServiceClient” is not a WebLogic Specific class rather it’s an Application or Third party class.
So first of all find out the JAR file which contains the Missing Class. Then try to Put it inside the Applications “lib” directory …either “<EAR_APP>APP-INFlib” (incase of EAR application) or inside “<WAR_APP>WEB-INFlib” (incase of WAR application).
If you dont want to put the Jar file inside the Application then Put the Jar file inside “<DOMAIN_HOME>lib” directory in all the Managed Server boxes, wherever you have deployed the Application
Or explicitely set the Missing Jar file in the Classpath of Server in the server StartScript. If you are are starting your Server using NodeManager then Please set the CLASSPATH like described in the following Link: http://middlewaremagic.com/weblogic/2010/03/26/nodemanager-based-managedservers-setting-mem_args/

I really thank you for you update. Apart of this I have another question is: when I am restarting a managed server in production environment, it was failed in Admin state. So when I clicked on Resume button for that perticular managed server, it’s become Active.could you please let me know what was the cause lead it to Admin state and how was it become Active when resumed ? Appreciates for quick reply..
August 31st, 2010 on 5:47 pm
Hi Praveen,
If a Server Moves to Admin State It means It is unable to activate some of the Modules which are deployed on this Server. usually it happens If any Application is Not getting activated properly or a Datasource or JTA recoveryor a JMS System/SubSystem is not getting activated properly then also it moves into the Admin State. So To find out the Root cause we need to keenly observer the Logs. Specially we need to check what configuration changes we made on the Server recently.
Still if we dont get much informations then based on our assumptions we may need to apply different Debug flags on that Server to get some more information’s on the Server Logs.

Hi Praveen,
I don’t have answer for that question right now…Because after Leaving Oracle WebLogic Server Support i don’t have access to the WebLogic Codes. but i will try to find that answer and will update you as soon as i get the answer.
But if you are facing this issue very frequently then i will recommend you to Open a Support ticket with Oracle on this. Because it is not good that the Serer goes into the Admin State.

please reply me.

September 21st, 2010 on 10:16 am
Hi Harry,
If you want to provide different Memory Arguments/Classpath to different Managed Servers then in that case you must have to create your own Separate Custom script to start ManagedServers. like “startManaagedOne.sh” and “startManagedTwo.sh”.
It is easy…Just make 2 copies of “startManagedWebLogic.sh” which is present inside your “<DOMAIN_HOME>bin” directory and then rename them as “startManaagedOne.sh” and “startManagedTwo.sh” …then edit them according to your Requirement.

If you are starting your servers using startScripts like startWebLogic.sh or startManagedWebLogic.sh then you can change the memory arguments using “setDomainEnv.cmd/sh” like described in Step-2) : http://middlewaremagic.com/weblogic/2010/09/03/why-and-how-oracle-jrockit/

Good Evening..
I’ve created new “WebLogic Domain” in production mode for WL version 10.3.3.
So whenever i start the adminServer , I was prompted to provide username/password.
In-order to avoid this , I tried the following way , but its not helpful for me –
1. Created a folder named security under
D:Weblogic Home 10user_projectsdomainswls_domain1serversAdminServer
2. Opened a notepad , and entered as
username=weblogic
password=weblogic
Saved the txt file with boot.properties under above mentioned path.
3. Stopped the adminServer
4. Started once again
But still i was asked to provide username/password..
Can you help me how to fix this ?
Thanks Much for your help.

Please confirm me on this..
MEM_ARGS, that we specify in the scripts,its at a Domain level Right?
Each and every JVM instance in the domain will have the same initial Memory and Max memory available, Right?
January 27th, 2011 on 10:57 am
Hi Sathya
By default the MEM_ARGS applies to the whole domain…because every scripot calls setDomainEnv.sh
But if you want different Managed Server should run with different memory args then you will need to create separate
startManaged_1.sh
startManaged_2.sh
startManaged_3.sh
with their own Memory settings defined in their own scripts….which is very easy …Just copy and paste the default “startManagedServer.sh” and add the JAVA_OPTIONS in that.

Hi Jay,
I have deployed the library file and ear files which i deploy will reference this library .
The state of lib file is showing as new , when i tried to stop it says the below.
The library has been excluded. Libraries are always managed as part of another application.
– Warning– All of the Deployments selected are currently in a state which is incompatible with this operation. No action will be performed.
How can i make that lib file as active .
I tried to stop the applications that reference this library file and tried to start the lib file but also it throws same error .
Could you please suggest me on this issue?
If i need to deploy the higher version of lib file , i need to undeploy the existing lib and deploy the new lib .But what will happen to the applications that reference the old library , Whether i need to undeploy those and redeploy ?
Thanks

February 23rd, 2011 on 11:58 pm
Hi Murali,
“A shared J2EE libraries or optional package cannot be undeployed until all applications that reference the library or package are first undeployed.” But for Shared Library upgrade , You can deploy a new version of the shared library by incrementing the implementation version in MANIFEST.MF and then undeploy the older version. That way there is always at least one version of the library available in the server to be a reference of other applications.

hi jay,
Just created an account in middlewaremagic,and this is my first post.
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.
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,which is hampering the performance
Pls help,
Thanks in advance

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.

hi jay,
I m new to weblogic,previously used to work on OAS10g,According to companies requirement shifted the entire application from OAS10g to weblogic 10.3.3
Just wanted to know Are there any good Documents for tuning weblogic 10.3.3?
Searched online but neva got any specify updates for specific parameters
from my end i have increased heap size and jvm size

Hi Ravish,
Here is a small problem f mine.
Im tryin using java weblogic.Server utility in an empty folder.
———————————————–
Please check the error in getting:
java weblogic.Server
/home1/deutschebank/chicagodomain/config/config.xml not found
No config.xml was found.
Would you like the server to create a default configuration and boot? (y/n): y
Enter username to boot WebLogic server:weblogic
————————————————
I have tried the below mentioned option:
In JAVA_OPTIONS
-Dweblogic.management.allowPasswordEcho=true
still getting the same error. Please let me know where is Native Library(terminalio) located so that i’d be able to try the same after settin it in classpath and PATH.
Thanks,

Hi Vidhan,
I have just used the same command after running the “setWLSENV,sh” which can be found in the path (wlserver_10.3/server/bin) on the same prompt and for me its working just fine as you can see in below output,
NOTE: Make sure you use an extra (.) dot when you run setWLSENV.sh like shown below and then run the your command.

hi Middleware team,
Since i have worked mostly on Oas 10g and now shifted to weblogic.I just wanted to know..whether this is possible on weblogic as well..Im not comparing it.
Like in OAS,i could generate a trace file (.trc) of a particular user ie we could come to know..from backend, what all queries are fired and we get a detailed description about how much bytes of data he is using from the network and This was helpful for finding out the root cause of minor issues faced by end users.
Regards

Hi Fabian,
You can use “Extended Access Logging” feature provided by WebLogic to extract more informations regarding the request processing as described in the following link:
http://download.oracle.com/docs/cd/E13222_01/wls/docs91/config_wls/web_server.html#elf
It can be enabled through Admin Console as well like:

Hi Jay / Ravish ,
Last week with the help of you both , i was able to install WebLogic-10.3.3.0 successfully on Ubuntu 10.4 , fine!
But I’m over coming with one wired issue ,
Issue –
1. Using “terminal” , initially installed weblogic ,fine.
2. And then created one sample domain , fine.
3. Before starting adminServer , i just thought of opening one more new terminal , and tail log file to just watch – so just clicked one more terminal.
,
Now plays interesting part and wired one was –
the already running terminal disappears , and even unable to open any other new terminals.
So i cant open/use any more terminals
Then after spending some time came to know what’s the issue –
“execute” permissions were deleting for /bin directory So anything accessible via /bin will NOT be accessible any more.
This is happening only after installing Weblogic , so there’s something going on after installing weblogic which making to delete execute permissions.
Do we have anything which making this happen ? any idea?
Do we have any place where we can check , or how this happening ?
Do we have any fix for this ?
How am i confirming tht only happening with weblogic installation means –
I tried uninstalling weblogic , and able to open “n” number of terminals without any issues.
Please let me know if anything was un-clear , i’ll explain once again..
Please help me here , because of this i am unable to practice weblogic.
Thanks
Kiran
April 14th, 2011 on 12:25 pm
Hi Kiran,
The problem of “Disappearing of Terminals” which you faced has nothing to do with WebLogic. Please contact your Operating System Administrator. WebLogic doesnot controls the Terminal in which it runs.

Hi Jay ,
I have some issue with one of my DB-Connection pool which was configured in DEV environment ( it’s standalone machine , targeted on adminserver only)
Doubt whether my pool has connection leak.
So i would like to monitor the open/closed/leaked connection of my data source , was it possible ?
I read on middlewareforums ( not sure whether site also maintained by you)
Steps –
In the JDBC Connection Pool—>Configuration—>Connections tab, click on Advanced options.
Click Enable Connection Leak Profiling then hit apply.
BUT i dont find check box like “Connection Leak Profiling”
I’m using WLS 10.3 version
Thanks
Kiran
April 14th, 2011 on 1:07 pm
Hi Kiran,
First of all middlewareforums is not maintained by us and we are no way affiliated with or a part of them. They are using the same look and feel for web pages as ours …That’s why we added our LOGO of MM around 3 months back in Middleware Magic to be easily distinguishable. There site was registered around December 2010.
So there is no relation between MiddlewareMagic and middlewareforums web site.
In WLS 10.3 version this is the correct path for Profile Connection Leak
JDBC Connection Pool —> Configuration [tab ]—> Diagnostics [sub-tab]
Also you could use our own PY scripts which would send you email also and would monitor your Data Source

Thanks for the clarification regarding site , just confused as they were also using the same color and look like magic web-site.
And found the option where this Profile Connection Leak exists as ur correct , it’s under Diagnostics tab.
And better i start using your PY scripts , they would help more..
thanks Ravish / Jay

Error message –
April 14th, 2011 on 3:36 pm
This is error i’m seeing in the logs :
14 Apr 2011 05:17:52,418 ERROR – weblogic.common.resourcepool.ResourceLimitException: No resources currently available in pool usrdb.tx.ds to allocate to applications, please increase the size of the pool and retry..
Maximum capacity is 15 , so do you want me to increase ? or do we first need to check anything-else ?
And suppose if i enable “Profile Connection Leak” , where i need to check/monitor things ?
Thanks
kiran
April 14th, 2011 on 4:00 pm
Hi Kiran,
From the error in log it seems that your application needs more connections however data source has been exhausted and all the 15 connection are been used.
Now the Maximum capacity is dependent on your application and environment requirement hence try to increase it with a good amount and check if its still running out.
You can monitor the connection from the console also from the below console path
JDBC Connection Pool —> Monitoring [tab ]—> Statistics [sub-tab]
For monitoring Leaked Connection Count you have to click on the link Customize this table which is on the same page just above the table and select “Leaked Connection Count” (You can also choose any other parameters if you like so the details of these parameters can be found in this link – http://download.oracle.com/docs/cd/E13222_01/wls/docs103/ConsoleHelp/pagehelp/J2EEappdeploymentsmonitorjdbctabletitle.html ) from the left-box to the right-box and hit Apply button. Now you can monitor the numbers
Regards,
Ravish Mody
April 14th, 2011 on 4:10 pm
Hi Ravish,
Under :-
JDBC Connection Pool —> Monitoring [tab ]—> Statistics [sub-tab]
I can see my data-source “running” fine. , and even i can test ( testing tab) the pool successfully without any errors.
anyways i’ll increase it from 15 – 25 , and check how this goes..
But , do we have any chance like check what all connections being in use currently , and find out if any connection was NOT released after use.. like this , any ?
thanks
kiran
April 14th, 2011 on 4:29 pm
Hi Kiran,
You can also choose the “Active Connections Current Count” to check the current connection used by your applications and as I told before you can choose any other parameters too as per your requirement.
Also you can use the following parameters for making sure the connection gets back to the pool if they are been open and been ideal for a given number of time
JDBC Connection Pool —> Configuration [tab ]—> Connection Pool [sub-tab]
Inactive Connection Timeout
Shrink Frequency

Can we deploy an application in exploded format in production. what is the difference/advantage between exploded and archive? Please help.
Thanks & Regards,
Sohel.
April 19th, 2011 on 2:01 pm
Hi Sohel,
As such there is no negative impact of deploying an application in Exploded format in production or development environments. The Only negative impact is ….Exploded Applications cannot be remotely deployed, Only Archived applications can be deployed remotely and Archived applications consumes less space in the disk space.

Hi,
I really need some help in resolving the problem I have in starting up managed servers after creating the clustered weblogic domain that includes OSB.
I have installed the following applications on 2 machines that I used to support the cluster:
OS : Windows XP
JAVA : jrmc-3.1.2-1.6.0-windows-ia32.exe
Weblogic software : osb1031_wls103_win32.exe
The weblogic and OSB software were installed correctly and I have the pointbase database started correctly. The Admin server and Nodemanagers started up correctly and the machines are reachable but the managed servers kept giving the boot identity file error messages when they are started from the Admin console.
I have tried everything from updating boot.properties on the managed servers, to changing the Admin Account password but i still get the same authentication errors. A new boot.properties file is usually created in the C:DomainsTEE_OSBserversTEESERVER1_MS1datanodemanager folder
I also tried to create the managed servers using WLST script and/or from the Admin console separately but all to no avail. I also tried to start up the managed server without the cluster but the same result.
The only time the managed servers started was when I started them from the command line and pass in the credentials.
What can I fix in the server that will allow me to be able to start the managed servers.
SEE error messages below:
TEESERVER1_MS1.out file

I just wanted to know few things related to Heap allocation.
Currently total of 22GB RAM is available in my one of the Vertual server. It has 5diff. domains. These domains allocatied of 7.5GB. When i try to increase the Heap for one domain, it is not allowing.
1) Can you please explain me how to find the total used Heap in vertual server ( if any unix command)?
2) Also pls let me know formula and how much we can allocate to Heap on the total memory?
Please help.

Hi to all, I have a question that I cannot find the answer to it, I tried to run the stopManagedWebLogic.sh on a nohup command, but it fails because it requests the user and password… I tired to change the boot.porperties, but couldn change a thing…
When I run the stopManagedWebLogic.sh without the nohup command, it runs perfectly! Any suggestions?
Thank you!
July 1st, 2011 on 3:58 am
Sorry for the inconvenience, I found out that you can open the startWebLogic.sh shell u can input the user and password, and it will run nicely on a nohup command
July 29th, 2011 on 12:28 pm
Hi Middleware Magic team,
Just came up with new doubt.Is this possible.
I have a Managed Server which is up and running.There are around 200-300 active users using the application.Now due to some reason,i have to stop this Managed server.I have msged all the users to log out and log in to application which is deployed on other Managed server.But still the users are connected to the old Managed server..I can forcefully stop managed server but the users will face some porblems.
So Is there a way to STOP the NEW users to connect to this old Managed Server..so that the old user who are already logged in will work and once they are done they will log out..and once all the users are logged out.I can stop the managed server.
Or is there any way to redirect the users to the new managed server.(According to me Redirecting is possible in Apache)
Regards,
Fabian
July 29th, 2011 on 5:38 pm
Hi Fabian,
I think you can try chosing the JDBC-based Persistent Storage for your HttpSessions so thet the Session Data of the currently Loged in Users will be persisted in the database even if you Shutdown/Crash the Managed Server which is having the Primary Http Sessions for your 200 Active users. And as soon as those iusers will click on the referesh button of the web page they will be redirected to the next available member of the cluster.
You can refer to the following article to know hw to achieve this: http://download.oracle.com/docs/cd/E11035_01/wls100/webapp/sessions.html#wp139726
weblogic.xml snippet
======================
<persistent-store-type>jdbc</persistent-store-type>
<persistent-store-pool>jdbc/SessionPersistenceDS</persistent-store-pool>
<persistent-store-table>WL_SERVLET_SESSIONS</persistent-store-table>
<jdbc-column-name-max-inactive-interval>jdbc</jdbc-column-name-max-inactive-interval>
<jdbc-connection-timeout-secs>60</jdbc-connection-timeout-secs>
You also need to create a “WL_SERVLET_SESSIONS” table in your Database and the Schema (DDL Query) of this table is already available in the above link as following:
create table wl_servlet_sessions
( wl_id VARCHAR2(100) NOT NULL,
wl_context_path VARCHAR2(100) NOT NULL,
wl_is_new CHAR(1),
wl_create_time NUMBER(20),
wl_is_valid CHAR(1),
wl_session_values LONG RAW,
wl_access_time NUMBER(20),
wl_max_inactive_interval INTEGER,
PRIMARY KEY (wl_id, wl_context_path) );

Hi Jay,
Thanks for the Reply,
Will try the above solution.
By the way, i did as follows which served my purpose as well.
I Just stopped the Managed server and Deployed file with “when Work completes”.Usually,i used to “Forcefully Stop” the Managed Server.
When i tried to shutdown with “when Work completes”.The new user trying to access the url used to get http 503 error,While the users who were logged in,were able to work with any problem.

Hi Middleware Magic Team,
I have Came up with a new Requirement.
Our Developer Has given a new war file.
He his trying establish database connection through datasource ie through connection pooling.
Previously,we had a war file in which the connection to the database was present IN the war file itself.
So now we are just trying to give the connection externally to weblogic
The developer has provided me context.xml file for tomcat,he wants that context.xml file specific for weblogic.
Searched Google for the same,Never got any specific solution for the same.
Right now,im confused Do we need context.xml file in weblogic or not.
Or is there any other file which i need to update
Our Developer has shared the below context.xml file for tomcat
?xml version=’1.0′ encoding=’utf-8′?
Context
WatchedResource WEB-INF/web.xml /WatchedResource
Resource name=”jdbc/PooledDB”

hello Jay,
We are getting an issue in production where an application is present on 2 servers on different machines on a horizontal cluster. The application is going down once every alternate day. It used to happen only on one server, but yesterday the other server also went down.
the environment: Windows 2k3, weblogic 9.2.3, horizontal cluster
This is what i can make from the log files.

well, we get a series of these messages and then that is followed by the java.lang.nullpointerexception shown above.
BEA-000628 Created “1” resources for pool “dsSAADE”, out of which “1” are available and “0” are unavailable.
BEA-000628 Created “1” resources for pool “dsSAAprod”, out of which “1” are available and “0” are unavailable.

Hi Rakeshreddy12345,
POINT-1).
If you are worrying about BEA-000628 messages … then there is nothing to worry because these are just INFO messages so There is no indication of a pool tuning problem or config issue at this time.
The huge repetition of these messages indicates that Application or the Database or the N/W is closing the connection and the application is asking the pool to provide another fresh connection, which invoked the pool’s test-on-reserve and replace. So that time you will see this message. If you really want to know what is happening with the Jdbc connections then please apply the JDBC related debug flags from the admin-console to get more information’s.
POINT-2).
If you are worrying about the NullPointerException then please consult with your Application Development team to know what exactly the Application code is doing at the following API:
java.lang.NullPointerException
at java.util.Arrays.binarySearch(Arrays.java:1711)
at com.nvd.saa.SaaCache.rutusArray(SaaCache.java:699)
Only Developers can tell us exactly what kind of actions are they performing at line 699 inside “com.nvd.saa.SaaCache” class “rutusArray” Method, which is throwing NullPointerException.

Hello Jay,
How do we send an email alert to an admin if the health state of the server is not OK, but the server state is RUNNING. This is happening for us and i want weblogic to send an email to me as soon as this happens and i want to restart this server as this happens.
Its happening in windows 2k3 production server. we are using weblogic server 9.2.2.0
August 29th, 2011 on 4:46 pm
Hi Rakeshreddy,
You can use the JMX code mentioned in the following link to get the Health State of your Different WebLogic Servers (http://middlewaremagic.com/weblogic/?p=2851) …. Run this JMX Code using Windows Scheduler ….
You can add the JAVA mail API to send E-Mail as soon as you get Health State If the Server Health is not desired. Please refer to the following article for more details on Sending Mails using Java API: http://www.javacommerce.com/displaypage.jsp?name=javamail.sql&id=18274

if an email is not desired, i want to just restart the server as soon as the health status is not OK ???
please help. thank you

Hi Rakeshreddy12345,
J2SE API has java.lang.Runtime class which contains exec() method to execute some commands or a Script or a Bat file… In the Previously mentioned JMX Code you can call the stopWebLogic.cmd and then startWebLogic.cmd scripts using that API ….If you find that the Server Health is not desired or not HEALTH_OK
Example:
http://www.java-tips.org/java-se-tips/java.util/from-runtime.exec-to-processbuilder.html
Example:
Runtime.getRuntime().exec(“cmd /c startWebLogic.bat”);

Hi Jay,
I am the following stats from one of my datasource:
Active Connections Average Count : 113
Active Connections Current Count : 0
Active Connections High Count : 197
Connection Delay Time : 111
Connections Total Count : 6389
Current Capacity : 120
Curr Capacity High Count : 190
Enabled : true
Leaked Connection Count : 0
Num Available : 120
Num Unavailable : 0
Prep Stmt Cache Current Size : 250
Highest Num Available : 200
Waiting For Connection High Count: 8
Initial Capacity : 5
Capacity Increment : 10
Maximum Capacity : 200
Statement Cache size :20
Inactive connection timeout : 0
1.From the stats i see there are Max of 200 connections and 120 available, but when does it settle down to 0 ? Currently we have ‘Active Connections Current Count = 0’ and timeout as Zero seconds. When does ‘Num available’ settle down to 0 ?
2. What does ‘Curr Capacity High Count ‘ , ‘Active Connections High Count’ and ‘Waiting For Connection High Count’ mean?
Thank you

Hi Manish,
1.From the stats i see there are Max of 200 connections and 120 available, but when does it settle down to 0 ?
Connections would not go to 0, this is because the Initial Capacity is set to 5. That means the lowest the connections can go to 5 and not 0.
Currently we have ‘Active Connections Current Count = 0′ and timeout as Zero seconds. When does ‘Num available’ settle down to 0 ?
‘Num available’ this also cannot go to the value 0 because of the above reason . However ‘Num available’ means current number of connections that are currently available to applications and not those connection which are being tested or refreshed, hence its always good to have “Num available” and “Current Capacity”
2. What does ‘Curr Capacity High Count ‘ , ‘Active Connections High Count’ and ‘Waiting For Connection High Count’ mean?
Curr Capacity High Count: Highest number of database connections available or in use (current capacity) in this instance of the data source since the data source was deployed.
Active Connections High Count: Highest number of active database connections in this instance of the data source since the data source was instantiated. Active connections are connections in use by an application.
Waiting For Connection High Count: Highest number of application requests concurrently waiting for a connection from this instance of the data source.

Hi Jay,
Thanks for your response.
What should i change to make the Num Available to settle down to Initial Capacity, because i see though there are no active connections the Num Available is the same and not settling down. I have Shrink Frequency of 900 Secs.
Thank you

Jay,
I have this error in the logs, i tried searching but find many reasons like , TCP/IP, memory , Database errors, but could not single out. What could be the possible reason for this error and what should i look for? I am pasting only few excerpts from the stack trace, the log is too big to paste here. I can send it in an email if you need for further diagnosis. Thanks for your time.

Hi Manish,
By default the ResultSet object which we receive from the IBM DB2 Driver is not scroll sensitive so if our application tries to iterate the previous record in the Results set then we face this issue, Because the IBM DB2 driver closes the object if we try to traverse in the resultSet in reverse direction So please make sure that your ResultSet object is Bidirectional / Scrollable… We can get the resultSet object like following to make it scrollable.
Statemen statement = connection.prepareCall(query, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
Or
Statemen statement = connection.createStatement(query, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
It is basically a DB2 Jdbc Driver BUG …it will be better if you can contact the IBM regarding the issue to get a fix.
