fyi, I just encountered a strange problem where a channel failure did not result in a channel event being generated. I didn't realize we had a problem until an application generated an email informing me of a connection problem. IBM says this is a known problem.

The behaviour has changed since the introduction of IC29815 so that "Channel Stopped" events are only generated when the channel program itself generates a stopped event. Customers will therefore find that if a channel goes straight into a retry mode after it is started, they will not get a MQRC_CHANNEL_STOPPED event with MQRQ_CHANNEL_STOPPED_RETRY. The confusing issue is that an MQRC_CHANNEL_STARTED event is written to the SYSTEM.ADMIN.CHANNEL.EVENT queue when the channel is started via runmqsc or the MQSeries Explorer, even if the channel isn't actually able to initialize a conversation with the remote end. The difference between the event generated by runmqsc/explorer and the channel process is that you can see the name of the process in the PutApplName: PutApplName : 'ebSphere MQ\bin\runmqchl.EXE' OR PutApplName : 'ebSphere MQ\bin\AMQPCSEA.EXE' Additionally the MQCFH will contain a blank conname if the channel process hasn't generated the event e.g: 00000000: 0700 0000 2400 0000 0100 0000 2E00 0000 '....$...........' 00000010: 0100 0000 0100 0000 0000 0000 EA08 0000 '............Û...' 00000020: 0200 0000 0400 0000 1800 0000 DF07 0000 '............?...' 00000030: 0000 0000 0400 0000 464F 4E5A 0400 0000 '........FONZ....' 00000040: 2400 0000 AD0D 0000 0000 0000 0D00 0000 '$...¡...........' 00000050: 464F 4E5A 2E54 4F2E 5249 4348 3300 0000 'FONZ.TO.RICH3...'

Future releases of MQSeries will provide a Channel stanza tuning parameter StopEvent = Always, which will revert to the old behaviour of always generating a STOP event.
