It seems odd that there is nothing in the AMQERR01.LOG for the qmgr for a Service failure.

It seems odd that there is no TRIGGER/NOTRIGGER attribute for the triggered application queue. Perhaps this is also a copy/paste failure.

It seems equally odd that CURDEPTH is zero for the triggered queue, the initiation queue, and the dead-letter queue.

Does the dead-letter queue exist? Does the qmgr know the name of the dead-letter queue?

If the trigger monitor could start up, but not launch the program, it would write errors to the stderr, or stdout, not throw a message into AMQERR01.LOG.

If NOTRIGGER was set, then the trigger monitor wouldn't work when run in the foreground.

CURDEPTH is presumable a point-in-time, rather than data from when the trigger monitor doesn't work.

mqjeff has pointed out the exact scenarios.

Yes there is a system default DLQ assigned for the QMGR.

I am really confused why the trigger monitor service is running but not triggerring the application whereas if i run in cmd prompt normally using runmqtrm it runs perfectly.

Any suggestions to check the services?

Well, again, check that the queue manager user has permissions to execute the triggered program (not the trigger monitor). Check that the queue manager user has permission to access the directories that lead up to the triggered program.

Check that the queue manager user has access to write to the stdout and stderr files you have named in the service definition.

Check that there is no information in those files.

Check that runmqtrm is even starting up when you start the service.

Please do these things as one test:

Start the Service, then check (with Windows Task Manager or Windows Process Explorer or equivalent) to see if the trigger monitor is running.

Next, put a message to the app queue; then, using the same tool, check to see if the triggered app comes to life.

Next, look for queue depth for the app queue, the initq, the dlq.

Look at the error log for this qmgr.

Look in the Windows Event Log.
