As an MQ administrator, you typically want to repeat the messages from one queue to a different queue for troubleshooting.
Use dmpmqmsg to repeat the MQ message
Copying messages from one queue to a different is feasible with a built-in program known as dmpmqmsg in IBM MQ8. On this article I clarify how to try this.
Situation – copy a message from LOCAL.Q1 to LOCAL.Q2 in CHANDAN.QMGR
I now have one message in LOCAL.Q1
dis ql(LOCAL.Q1) curdepth 1 : dis ql(LOCAL.Q1) curdepth AMQ8409: Show Queue particulars. QUEUE(LOCAL.Q1) TYPE(QLOCAL) CURDEPTH(1)
To repeat, I’ll use dmpmqmsg program.
dmpmqmsg –m QMGR –i SOURCE.QUEUE –o TARGET.QUEUE-bash-4.2$ ./dmpmqmsg -m CHANDAN.QMGR -i LOCAL.Q1 -o LOCAL.Q2 5724-H72 (C) Copyright IBM Corp. 1994, 2015. WebSphere MQ Queue Load/Unload Utility Learn - Information: 0 Messages: 1 Bytes: 39 Written - Information: 0 Messages: 1 Bytes: 39 -bash-4.2$
The message is copied from LOCAL.Q1 to LOCAL.Q2.
Let’s confirm them.
dis ql(LOCAL.Q2) curdepth 1 : dis ql(LOCAL.Q2) curdepth AMQ8409: Show Queue particulars. QUEUE(LOCAL.Q2) TYPE(QLOCAL) CURDEPTH(1)
So you’ll be able to see that the message has now been copied to LOCAL.Q2.
