Hi,
I've been noticing some of the messages are getting generated by Qmgr of format type MQTRIG. And Messages are routed to DLQ and then Forwarded to DLQBACKUP using Rule Table. But the Question is in what scenario(s) we see this MQTRIG Messages.
Where as Trigger MOnitor is ON and Running fine since Long.
InitQ curdepth is 0 and having handle of trigger monitor. Put and Get are enabled for this Queue.
I don't see any Error in the QMgr Error Logs, which I suspected, could have been generated cause of Trigger Monitor Issue Or someother.
There is no FDC either.

You could obfuscate it you know.
Replace company names with XXXXX
etc
etc
etc
Jest leave the paths etc the same
My guess is that Morag is more interested in the structure of the data than the content at this stage.

I've the message format .. in hex.. and some of it is in readable format. I can obfuscate some of the readable.. but still hex can be converted to readable.. and if I play with hex.. the structure would be of no use (i guess)

I trust her. No doubt about that.  But I don't trust others who would be ready for phishing.

MQTRIG messages shouldn't, to the best of my knowledge, contain any business data.
So that's the first thing to notice. Either it's an MQTRIG message that is properly created by the queue manager, or it's an MQTRIG message that is improperly created by an application. |

| Code: |
MQCHAR256 ApplId; /* Application identifier */
MQCHAR128 EnvData; /* Environment data */
MQCHAR128 UserData; /* User data */
|
Those fields can contain company names, user names, path data and other 'stuff' the some might regards as sensitive.

my guess is you're getting the msgs in the DLQ because of something wrong... In case you are running one of the standard trigger monitors and not your own... :
First thing to consider is the DLQ reason code.
Second thing is to run a trigger monitor log and look at it.
Third thing would be to run the trigger monitor in foreground.
Last but not least: Identify and fix the problem!

Messages are flowing down to DLQBACKUP queue from the DLQ queue based on if Format is MQTRIG (by Rule Table).
Messages are getting routed to DLQ with reason 265 (Appl can not be started) MQFB_APPL_CANNOT_BE_STARTED.

So, the app fails to start in background ( &). Can you successfully run the application interactively?

app fails to start in background is an assumption at this moment. but it is confirmed with above reason code that application failed to start.
Haven't tried to execute that application interactively cause its an application owned process/job, we can not play with it in the environment which is critical.
app fails to start in background can be confirmed if we run the trace.
