Hi,
I need some assistance with durable messaging subscription. I am runing MQ V5.3 CSD 12 on Solaris.

There is an application that when lauched creates 4 durable subscribers for 4 different topics. The application recieves messages for aproximately 5 minutes and then nothing. There are no errors in the error log and there are no messages on subscription queue and no errors in Java application.

This all started when accidently the durable subscription queue got filled up. We cleared it and since then this problem.

Anys suggestions would be much appreciated.

Does the log show anything about log files being full? Is it possible that when you cleared msgs, the UOWs were not committed/rolledback?

Hi,
I did not personally delete the messages. They just disappeared. Something might have happened in the application.

From IBM support, they have stated that it looks like the publisher is not publishing to the subscribers. As stated before started happening after the queue got full.

Right now even when we unsubscribe and resubscribe using different client ID nothing comes to the application. If they subscribe as non-durable everything works fine.

IBM recommended changing SUBSTORE to BROKER from MIGRATE. Not sure what impact that has on the application. Will have to test that.

Any suggestions would be appreciated.
