There is one other option. You can request from IBM a program, CSQ4SYNC, that examines the Channel SYNCQ and either reports on or removes the duplicates.

The problem I see here in purging all the messages in this queue is having to reset the sequence numbers in our side and in all other Q managers we talk to. This last piece, resetting other Q managers, which takes a lot of coordination and causes outage, is something that we cannot afford. This is the reason why I am trying to find which messages should be kept and which ones can be purged.

But I don't think this info has changed... You can safely delete any message from the SYNCQ, BUT... If you do, you will need to do a message number Reset for any existing channels whose information you delete. This queue is where that kind of information is stored. I once deleted every message from this queue when we had a pretty off the wall problem with the queue caused by a power failure combined with a UPS failure, and we survived (although all those resets were a pain). I'd suggest (strongly) you do this at a time when your CHIN is down; actually, I'm not sure you can do it otherwise. What I would do is shutdown the CHIN, dump the queue to a flat file using CSQUTIL, then delete what you want, then restart the CHIN and see what happens. If you find it's royally messed up, you should be able to reload the old SYNCQ from your backup. Good luck ...

I have been unable to find a way to determine which messages are needed which messages are not. Does anyone out there have any experience with this issue? We are running MQ for OS/390 V2.1.
