I have a trigger process that I am happy with. Our infrastructure folks recycle that server nightly (including taking down all Queue Managers). When the QM restarts, I am seeing the trigger fire when not expected. Given the intended audience, false positives could be painful.
The qlocal is defined as below (heavily snipped).
| Code: |
QUEUE(RESUBMIT.QUEUE) TYPE(QLOCAL)
CURDEPTH(0) DEFBIND(OPEN)
GET(ENABLED) HARDENBO
INITQ(RESUBMIT.INIT.QUEUE) IPPROCS(0)
TRIGGER NPMCLASS(NORMAL)
OPPROCS(0) PROCESS(RESUBMIT_APP)
TRIGDATA( ) TRIGDPTH(1)
TRIGMPRI(0) TRIGTYPE(FIRST)
USAGE(NORMAL)
|
My service is defined as:
| Code: |
SERVICE(RESUBMIT_TRIG_MON) CONTROL(QMGR)
SERVTYPE(SERVER) STARTCMD(/opt/mqm/bin/runmqtrm)
STARTARG(-m +QMNAME+ -q RESUBMIT.INIT.QUEUE)
STOPCMD(/opt/mqm/bin/amqsstop)
STOPARG(-m +QMNAME+ -p +MQ_SERVER_PID+) |
I was able to find a [very]+ detailed description of necessary conditions for a trigger to fire on the IBM library site.
Is there a similar discussion for how triggering is handled on Queue Manager startup? My search attempts came up empty.

The queue manager evaluates the trigger conditions as normal at startup.

The queue manager evaluates the trigger conditions as normal at startup. |
With one exception however... It will start the triggered process if the queue depth has reached the threshold and no consuming process is running.
More identical to turning the trigger attribute off and then back on, on the queue.

Simplistically, all the attributes "turn on" as the queue manager starts.
