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 file “domain.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

Initializing WebLogic Scripting Tool (WLST) ...

Welcome to WebLogic Server Administration Scripting Shell

Type help() for help on available commands
