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

Ravish Mody

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:WLSTMove_Messages”

Step2). Write a Properties filedomain.properties inside “C:WLSTMove_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) ...

How to Move Messages From One Queue To Another Queue Using WLST

Ravish Mody

Two days back one of our subscribers Pavan had asked us by using comment , that is it possible to move the messages from one queue to another queue that to using WLST and the answer to that question is YES. It is possible to do the same using WLST and we have created the WLST script.

This is a very simple script which would just collect the target/destination queue where the messages has to be moved to (i.e. new.queue.name) and then would just go to the queue where the messages has to be moved from(i.e. old.queue.name). 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.

Steps to Move Messages From One Queue To Another Queue Using WLST

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

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

server.url=t3://localhost:8001
username=weblogic
password=weblogic

system.module.name=MySystemModule

old.server.name=AdminServer
old.jms.server.name=Admin_JMSServer
old.queue.name=Admin_Queue

new.tragated.server.name=AdminServer
new.jms.server.name=MyJMSServer
new.queue.name=MyTestQueue

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

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

systemModuleName = configProps.get("system.module.name")

oldServerName = configProps.get("old.server.name")
oldJmsServerName = configProps.get("old.jms.server.name")
oldQueueName = configProps.get("old.queue.name")

newTragatedServerName = configProps.get("new.tragated.server.name")
newJmsServerName = configProps.get("new.jms.server.name")
newQueueName = configProps.get("new.queue.name")

connect(Username,Password,serverUrl)

serverRuntime()

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

cd('/JMSRuntime/'+oldServerName+'.jms/JMSServers/'+oldJmsServerName+'/Destinations/'+systemModuleName +'!'+ 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

Note:

Only for Pava you would have to do the following changes
– Instead for line number – 34
cd('/JMSRuntime/'+oldServerName+'.jms/JMSServers/'+oldJmsServerName+'/Destinations/'+systemModuleName +'!'+newJmsServerName+'@'+ newQueueName)
- Instead for line number - 38
cd('/JMSRuntime/'+oldServerName+'.jms/JMSServers/'+oldJmsServerName+'/Destinations/'+systemModuleName +'!'+oldJmsServerName+'@'+ oldQueueName)

How To Pause and Resume A Queue Using WLST

Ravish Mody

Today one of our subscribers Pavan had asked us by using comment , Here based on the query of Pavan we are writing the following article, which would Pause the Queue at Runtime even when the AdminServer/AdminConsole  is unavailable, thus we took out sometime and just now created a WLST script which would do the same job very easily.

In this script you can choose from which end do you want Queue to get paused, say if you want to pause the messages to be inserted then you can use pauseProduction , if you need that the consumption from the queue should stop then use pauseConsumtion and if you want that Queue should not insert or consume then use both. This way you can pause the queue as per your requirement, also with this you can resume the queue too by using resumeProduction, resumeConsumption or both of them. 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.

Steps to Pause and Resume A Queue Using WLST

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

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

server.url=t3://10.10.10.10:7003
username=weblogic
password=weblogic
tragated.server.name=MS-1
jms.server.name=JMSServer-1
system.module.name=SystemModule-1
queue.name=Q-1

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

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

tragatedServerName = configProps.get("tragated.server.name")
jmsServerName = configProps.get("jms.server.name")
systemModuleName = configProps.get("system.module.name")
queueName = configProps.get("queue.name")

connect(Username,Password,serverUrl)
serverRuntime()
cd('JMSRuntime/'+tragatedServerName+'.jms/JMSServers/'+jmsServerName+'/Destinations/'+systemModuleName +'!'+ queueName)

##################
# To PAUSE A Queue
##################

######## This would NOT let the messages Insert in the queue but it would let the messages get Consumed  ###########
cmo.pauseProduction()
print 'Queue: "', queueName ,'" has been PRODUCTION Paused Successfully'

######## This would let the messages Insert in the queue but it would NOT let the messages get Consumed  ###########
cmo.pauseConsumption()
print 'Queue: "', queueName ,'" has been CONSUMPTION Paused Successfully'

###################
# To RESUME A Queue
###################

#cmo.resumeProduction()
#print 'Queue: "', queueName ,'" has been PRODUCTION Resumed Successfully'

#cmo.resumeConsumption()
#print 'Queue: "', queueName ,'" has been CONSUMPTION Resumed Successfully'

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….
