Middleware Magic Completes 2 year of spreading its Magic

It’s a pleasure to announce that Middleware Magic is celebrating it’s second anniversary today. We are now two years old today.

For new readers, we started Middleware Magic 2 years back and started as a tech blog for only Weblogic and with time we found that lot of new stuff is going on JBoss which caught our eyes, hence a year back exactly this day we had started tech blogging on JBoss as well and with it we really started making magic in the world of middleware.

Weblogic

JBoss

We always have a keen eye on our growing numbers and it’s really good to see we are growing with time and we are spreading the news like always in the world of middleware technology. This year for the total page views hit [i.e. JBoss + Weblogic] and total social network followers [i.e. Facebook + Twitter + Google] are

Pages Views 1,88,000+
Social Network followers 1140+

And special thanks to all the guys who took interests in joining our team and we are eagerly waiting for your articles to get them published on middleware magic with your name on it. We would also like to thank our subscribers from for supporting us and our teams [René van Wijk, Ravish Mody and Jay SenSharma] hard work as well as for bringing us to this stage and making middleware magic such a huge platform for everyone else.


Setup JMS with Unit-Of-Order using WLST

Ravish Mody

Yesterday one of our subscribers Miguel had asked us using comment how to configure the Unit-of-Order property using WLST script, as he was already able to create a JMSServer, JMSModule and JMS Connection Factory using a wlst script but was having an issue setting the  Unit-of-Order property, hence it seemed to be a great topic to create an article on it. With below single script you can create and target following components.

  1. JMSServer
  2. JMSModule
  3. Queue
  4. ConnectionFactory
  5. Unit-Of-Order

As usual we have used a properties file which has all the required details in it like the JMSServer, JMSModule, Queue, ConnectionFactory names, targets name etc. This way you would not have to modify anything in your actual WLST script.

Setup JMS with Unit-Of-Order using WLST

Step1). Create a Directory somewhere in your file system like : “C:WLSTJMS

Step2). Write a Properties filedomain.properties inside “C:WLSTJMS” like following:

# 1 - Connecting details
server.url = t3://localhost:7001
username = weblogic
password = weblogic

# 2 - JMSServer details
jms.server.name = My_JMSServer
store.name = MyJDBCStore
tragated.jms.server.name = AdminServer

# 3 - SystemModule Details
system.module.name = My_SystemModule
tragated.system.module.name = AdminServer

# 4 - ConnectionFactory Details
connection.factory.name = My_ConnectionFactory
connection.factory.jndi.name = My_CF

# 5 - Unit Of Order Details
unit.of.order.value = 1

# 6 - SubDeployment & Queue Details
queue.sub.deployment.name = Sub_My_Queue
queue.name = My_Queue
queue.jndi.name = My_Q

Step2). Now in the same directory write the following WLST Script “JMS_Setup.py” like following:

from java.io import FileInputStream
import java.lang
import os
import string

propInputStream = FileInputStream("domain.properties")
configProps = Properties()
configProps.load(propInputStream)

# 1 - Connecting details
serverUrl = configProps.get("server.url")
Username = configProps.get("username")
Password = configProps.get("password")

# 2 - JMSServer details
jmsServerName = configProps.get("jms.server.name")
storeName = configProps.get("store.name")
tragatedJMSServerName = configProps.get("tragated.jms.server.name")

# 3 - SystemModule Details
systemModuleName = configProps.get("system.module.name")
tragatedSystemModuleName = configProps.get("tragated.system.module.name")

# 4 - ConnectionFactory Details
connectionFactoryName = configProps.get("connection.factory.name")
ConnectionFactoryJNDIName = configProps.get("connection.factory.jndi.name")

# 5 - Unit Of Order Details
unitOfOrderValue = configProps.get("unit.of.order.value")

# 6 - SubDeployment & Queue Details
queueSubDeploymentName = configProps.get("queue.sub.deployment.name")
queueName = configProps.get("queue.name")
queueJNDIName = configProps.get("queue.jndi.name")

redirect('wlst.log','false')

# 1 - Connecting to the Destination 
connect(Username,Password,serverUrl)

edit()

# 2 - JMSServer details
print "================== JMSSever ==================="
startEdit()
cmo.createJMSServer(jmsServerName)
print "Created a JMSServer !!"
cd('/Deployments/'+jmsServerName)
cmo.setPersistentStore(getMBean('/JDBCStores/'+storeName))
print "PersistentStore has been set for the JMSServer !!"
set('Targets',jarray.array([ObjectName('com.bea:Name='+tragatedJMSServerName+',Type=Server')], ObjectName))
print "Targeted the JMSServer !!"
activate()
print ""

# 3 - SystemModule Details
print "================== SystemModule ==================="
startEdit()
cd('/')
cmo.createJMSSystemResource(systemModuleName)
print "Created a SystemModule !!"
cd('/SystemResources/'+systemModuleName)
set('Targets',jarray.array([ObjectName('com.bea:Name='+tragatedSystemModuleName+',Type=Server')], ObjectName))
print "Targeted the SystemModule !!"
activate()
print ""

# 4 - ConnectionFactory Details
print "================== ConnectionFactory ==================="
startEdit()
cd('/JMSSystemResources/'+systemModuleName+'/JMSResource/'+systemModuleName)
cmo.createConnectionFactory(connectionFactoryName)
cd('/JMSSystemResources/'+systemModuleName+'/JMSResource/'+systemModuleName+'/ConnectionFactories/'+connectionFactoryName)
cmo.setJNDIName(ConnectionFactoryJNDIName)
print "Created a ConnectionFactory !!"
cd('/JMSSystemResources/'+systemModuleName+'/JMSResource/'+systemModuleName+'/ConnectionFactories/'+connectionFactoryName+'/SecurityParams/'+connectionFactoryName)
cmo.setAttachJMSXUserId(false)
cd('/JMSSystemResources/'+systemModuleName+'/JMSResource/'+systemModuleName+'/ConnectionFactories/'+connectionFactoryName)
cmo.setDefaultTargetingEnabled(true)
print "Targeted the ConnectionFactory !!"
activate()
print ""

# 5 - Unit Of Order Details
print "================== Unit Of Order ==================="
startEdit()
cd('/JMSSystemResources/'+systemModuleName+'/JMSResource/'+systemModuleName+'/ConnectionFactories/'+connectionFactoryName+'/DefaultDeliveryParams/'+connectionFactoryName)
cmo.setDefaultUnitOfOrder(unitOfOrderValue)
print "Changed Unit Of Order !!"
activate()
print ""

# 6 - SubDeployment & Queue Details
print "================== SubDeployment & Queue ==================="
startEdit()
cd('/SystemResources/'+systemModuleName)
cmo.createSubDeployment(queueSubDeploymentName)
print "Created a SubDeployment for Queue !!"
cd('/JMSSystemResources/'+systemModuleName+'/JMSResource/'+systemModuleName)
cmo.createQueue(queueName)
print "Created a Queue !!"
cd('/JMSSystemResources/'+systemModuleName+'/JMSResource/'+systemModuleName+'/Queues/'+queueName)
cmo.setJNDIName(queueJNDIName)
cmo.setSubDeploymentName(queueSubDeploymentName)
cd('/SystemResources/'+systemModuleName+'/SubDeployments/'+queueSubDeploymentName)
set('Targets',jarray.array([ObjectName('com.bea:Name='+jmsServerName+',Type=JMSServer')], ObjectName))
print "Targeted the Queue to the created subdeployment !!"
activate()
print ""

cmd = "rm -f wlst.log"
os.system(cmd)

Step3). Now Open a Command/Shell Prompt and then run the “setWLSEnv.sh” script to set the CLASSPATH and PATH environment variables. Run the “. ./setWLSEnv.sh” by adding two DOTs separated by a single space …..before the actual script like following : (use ‘cd’ command to move inside the <BEA_HOME>/wlserver_10.3/server/bin) then run the following command….
. ./setWLSEnv.sh

Note: Here The first DOT represents that set the Environment in the current Shell, AND the second ./ represents execute the script from the current directory.

Step4). Run the Above WLST Script like following:

java weblogic.WLST JMS_Setup.py

Following would be the Output

java weblogic.WLST JMS_Setup.py

Target and Untargeting of Multiple DataSources using WLST

Ravish Mody

Yesterday one of our subscribers Ravi Shankar Kumar had asked us using comment how to target and untarget multiple datasources in the same domian using a single generic WLST script, as they have total 5 clusters and want to target each cluster to different datasources and as per his requirement we created this simple WLST script which can do the same things in this single script.

As usual we have used a properties file which has all the required details in it like the datasources names, targets name and number of datasoures which has to be updated. This way you would not have to modify anything in your actual WLST script.

Target and Untargeting of Multiple DataSources using WLST

Step1). Create a Directory somewhere in your file system like : “C:WLSTDataSource

Step2). Write a Properties fileDsDetails.properties inside “C:WLSTDataSource” like following:

userName=weblogic
password=weblogic
admin.Url=t3://localhost:7001

####### DataSources names ######
ds.Name.1 = MyJDBC_Data_Source-1
ds.Name.2 = MyJDBC_Data_Source-2

##### DataSources Target names #####
target.1= Cluster
target.2= Cluster-0

##### Total Numbers of DataSources has to be modified  #####
total.Ds.Count=2

Step2). Now in the same directory write the following WLST Script “Tragate_UnTragate_DS.py” like following:

#############################################################################
#
# @author Copyright (c) 2010 - 2011 by Middleware Magic, All Rights Reserved.
#
#############################################################################

from java.io import FileInputStream

propInputStream = FileInputStream("DsDetails.properties")
configProps = Properties()
configProps.load(propInputStream)

userName = configProps.get("userName")
password = configProps.get("password")
adminUrl = configProps.get("admin.Url")
totalDsCount = configProps.get("total.Ds.Count")

connect(userName,password,adminUrl)
edit()
startEdit()
print ''
print '======================================================================'
print 'UnTargeting and Targeting of the DataSources has started.....'
print '======================================================================'

dsCount=1
while (dsCount <= int(totalDsCount)) :
	dsName = configProps.get("ds.Name."+ str(dsCount))
	tgName = configProps.get("target."+ str(dsCount))
	cd ('/JDBCSystemResources/'+ dsName)
	set('Targets',jarray.array([], ObjectName))
	print ''
	print 'DataSource = ', dsName ,', has been UnTargeted'
	set('Targets',jarray.array([ObjectName('com.bea:Name='+tgName+',Type=Cluster')], ObjectName))
	print 'Congrats!!! DataSource = ', dsName ,', now has been Targeted to "',tgName,'"'
	print ''
	dsCount = dsCount + 1

print '======================================================================'
print 'UnTrageting and Targeting of the DataSources has been completed !!!'
print '======================================================================'
print ''

activate()
exit()

Step3). Now Open a Command/Shell Prompt and then run the “setWLSEnv.sh” script to set the CLASSPATH and PATH environment variables. Run the “. ./setWLSEnv.sh” by adding two DOTs separated by a single space …..before the actual script like following : (use ‘cd’ command to move inside the <BEA_HOME>/wlserver_10.3/server/bin) then run the following command….
. ./setWLSEnv.sh

Note: Here The first DOT represents that set the Environment in the current Shell, AND the second ./ represents execute the script from the current directory.

Step4). Run the Above WLST Script like following:

java weblogic.WLST Tragate_UnTragate_DS.py

Following would be the Output


java weblogic.WLST Tragate_UnTragate_DS.py
