WLST move JMS messages

Thanks to our friends of MiddleWare Magic:

http://middlewaremagic.com/weblogic/?p=6765

that I will never praise enough...



connect('weblogic', 'welcome1', 't3://pierrepc:7011')
easeSyntax()
serverRuntime()
cd('/JMSRuntime/ms1.jms/JMSServers/jmsserver1/Destinations/MS1SystemModule!Q2')
q2 = cmo
cd('/JMSRuntime/ms1.jms/JMSServers/jmsserver1/Destinations/MS1SystemModule!Q1')
q1 = cmo
#THIS WILL MOVE MESSAGES
q1.moveMessages('', q2.getDestinationInfo())

To move messages in small chunks, rather than all in a go:

from weblogic.jms.extensions import JMSMessageInfo
connect('weblogic', 'weblogic1', 't3://acme.com:10001')  
easeSyntax()
serverRuntime()

chunkSize = 25

cd /JMSRuntime/osbpl1ms1.jms/JMSServers/CommonJmsServer1/Destinations/GM_StockDownloadJMSModule!CommonJmsServer1@StockDownloadReprocessQ
sourceQueue = cmo
cd /JMSRuntime/osbpl1ms1.jms/JMSServers/CommonJmsServer1/Destinations/GM_StockDownloadJMSModule!CommonJmsServer1@StockDownloadQ
destinationQueue = cmo

sourceCursor = sourceQueue.getMessages('', 0)
sourceCursorSize = sourceQueue.getCursorSize(sourceCursor)
print "there are", sourceCursorSize, "in source"

sourceMessages = sourceQueue.getNext(sourceCursor, chunkSize )

if sourceMessages != None:
    for message in sourceMessages:
        msgwithbody = JMSMessageInfo(message)
        messageId = msgwithbody.getMessage().getJMSMessageID()
        print 'Message ID           - ' + messageId
        sourceQueue.moveMessages("JMSMessageID='" + messageId + "'", destinationQueue.getDestinationInfo())



Additional useful code:

#move messages to destination
sourceQueue.moveMessages('', destinationQueue.getDestinationInfo())

#send them back to origin
destinationQueue.moveMessages('', sourceQueue.getDestinationInfo())

Move a message based on a Selector messageId = "some id":

sourceQueue.moveMessages("JMSMessageID='ID:<64972.1369647706567.0>'", destinationQueue.getDestinationInfo()) Funnily, if I run:

destinationQueue.importMessages(sourceMessages, True) I get an error message:

importMessages operation not supported with replaceOnly=true

Hi,

when I use cmo.getMessages('',0) I get the below error:

san, the best thing is to execute manually, line by line, the script, and interactively examine your MBean tree using ls() . Probably you are using a different name for the JMS server or other resources...
