All,

I've communication set up between 2 Queue managers (from QM1 to QM2) with sender, receiver channels.

Also, in the TX queue of QM1, I've specified the name of the sender channel under Triggering -> Trigger Data and initiation Q as "SYSTEM.CHANNEL.INITQ".

Everything works fine except for the following:
After around few thousand messages go through, the messages start stacking in the sender QM's (QM1's) transmission queue and the sender channel's status says retrying.

I have to manually do a resolve, and then stop/start for the sender channel to get up and running.

Am I doing something wrong? any suggestions?

WMQ Level : 6.0.2.0

Thanks, V

Look at the queue managers error logs on both ends.

After around few thousand messages...

What is the MAXDEPTH of the destination queue at the receiving end? 1000?

Do you have a dead-letter queue at the receiving end?

Post here the remote QMGR attributes.

Post here the definition of the DLQ at remote qmgr.

A guess: you have maxqdepth set at 1000 (or thereabouts); you have no dead-letter queue at the receiving end.

When the Message Channel Agent at the receiving end can't put messages in the destination queue, it tries to put them into the dead-letter queue. If this fails, the channel goes into retry (and eventually fails). Working as designed.

First look at the error messages in your c:\ibm\webspheremq\qmgr\errors\amqerror*.log file.

Thanks

You assumed he was on Windows. The error logs are other places on Unix, AS/400 and z/OS platforms !
