Today one of our subscribers Pavan had  come back saying that the WLST script which was created by us previously How to Move Messages From One Queue To Another Queue Using WLST was only “working to move the messages from one queue to another queue which are on the same servers only“  by using comment , and as per his requirement they need to move the messages from Queue-1 to Queue-2 which are targeted to Server-1 and Server-2 respectively. Hence I have just made few modification in my previous script and thus this is the update version of it

I had to add two URL’s to get connected to the with the respective servers and also added two System Module this way you can move the messages from any Source Server to the Destination Server which can be in the same module or if the destination server is in different system module too this way its more flexible. All this can be done using the same script just give the domain and there servers details in the domain.properties files and you are good to go.

[Updated Version] Steps to Move Messages From One Queue To Another Queue Using WLST

Step1). Create a Directory somewhere in your file system like : “C:\WLST\Move_Messages”

Step2). Write a Properties filedomain.properties inside “C:\WLST\Move_Messages” like following:

######################
#    Destination
######################
new.server.url=t3://localhost:8003
new.system.module.name=SystemModule2
new.tragated.server.name=MS-2
new.jms.server.name=JMSServer2
new.queue.name=Q2

######################
#	Source
######################
old.server.url=t3://localhost:8002
old.system.module.name=SystemModule1
old.tragated.server.name=MS-1
old.jms.server.name=JMSServer1
old.queue.name=Q1

username=weblogic
password=weblogic

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

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

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

newserverUrl = configProps.get("new.server.url")
newsystemModuleName = configProps.get("new.system.module.name")
newTragatedServerName = configProps.get("new.tragated.server.name")
newJmsServerName = configProps.get("new.jms.server.name")
newQueueName = configProps.get("new.queue.name")

oldserverUrl = configProps.get("old.server.url")
oldsystemModuleName = configProps.get("old.system.module.name")
oldTragatedServerName = configProps.get("old.tragated.server.name")
oldJmsServerName = configProps.get("old.jms.server.name")
oldQueueName = configProps.get("old.queue.name")

Username = configProps.get("username")
Password = configProps.get("password")

# Connecting to the Destination
connect(Username,Password,newserverUrl)
serverRuntime()

print 'Getting the traget...'
cd('/JMSRuntime/'+newTragatedServerName+'.jms/JMSServers/'+newJmsServerName+'/Destinations/'+newsystemModuleName +'!'+ newQueueName)
target = cmo.getDestinationInfo()
print 'Got the traget...'

disconnect()
print ''

# Connecting to the Source
connect(Username,Password,oldserverUrl)
serverRuntime()
cd('/JMSRuntime/'+oldTragatedServerName+'.jms/JMSServers/'+oldJmsServerName+'/Destinations/'+oldsystemModuleName +'!'+ oldQueueName)

print 'Moving the messages to the new traget...'
cmo.moveMessages('',target)
print 'Messages have been moved to the traget Successfully !!!'

print '===================================================================================='
print 'Messages from queue: "'+oldQueueName+'" have been moved to the new queue: "'+newQueueName+'" Successfully !!!'
print '===================================================================================='

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 move_messages.py

Following would be the Output

java weblogic.WLST move_messages.py

Initializing WebLogic Scripting Tool (WLST) ...

Welcome to WebLogic Server Administration Scripting Shell

Type help() for help on available commands

Moving the messages to the new traget...
Messages have been moved to the traget Successfully !!!
====================================================================================
Messages from queue: "Q1" have been moved to the new queue: "Q2" Successfully !!!

Note:

Pava you would have to change the line number – 35  & 45 as per your environment
