Hello,
I am trying to enable a triggering event, but somehow I am unable to get the trigger message in the initiation queue. Would you please help to identify if I am missing something basic and obvious?
***** Define Initiation Queue *****
define qlocal(TEST.TRIGGER.INIT.Q)
***** Define application specific queue with triggering event *****
define qlocal(TEST.TRIGGER.Q) TRIGTYPE(DEPTH) TRIGMPRI(0) TRIGDPTH(5) TRIGDATA('clear qlocal(TEST.TRIGGER.Q) | runmqsc QMESB01') INITQ(TEST.TRIGGER.INIT.Q)
I thought process definition is not mandatory at least to get trigger message in the initiation queue. Even I tried with process definition.
***** Define a process *****
define process(self.clear.queue) APPLICID('/u/tghosh/temp_unix/clear.qlocal.ksh') APPLTYPE(UNIX) DESCR('Process to clear self queue after certain q depth')
ALTER QLOCAL(TEST.TRIGGER.Q) PROCESS(self.clear.queue)
I put multiple messages into the application queue (multiples of 5) but trigger event's not getting generated. tried to execute trigger monitor..
**** Execute trigger monitor *****
runmqtrm -m QMESB01 -q TEST.TRIGGER.INIT.Q
AIX 7.1 WMQ 7.5.0.5 |

The trigger will only be generated when the queue goes from 4 messages to 5.
Not "every five messages".
Can you see the initq open for input?
Does anything get reported to the stdout of runmqtrm ?

The trigger monitor needs to be running before messages go into the queue on which triggering is set, and if you trigger on depth the trigger should be reset by the application servicing the queue, after the queue has been cleared.

Please remember that you cannot test you triggering setup and check your triggering definitions by looking for the messages on the INITQ manually. If your trigger monitor is not running, and thus the INITQ is not open, a trigger message will not be created.

Thank you seniors.... I had wrong idea ... I thought it would be for every 5 message and I would be able to see message in INIT queue..
When I ran command to start trigger monitor, it had some output.
I'll try again and update my findings.
Thanks for your valuable responses. |

Hello,
I re-created the queue after deleting and I can see IPPROCS for INITQ as 1. Here goes the output for trigger monitor which I can see is picking up. Would you please guide about the trigger data format to be used if I want to pass parameters to a common process?
define qlocal(TEST.TRIGGER.Q) TRIGGER TRIGTYPE(DEPTH) TRIGMPRI(0) TRIGDPTH(5) TRIGDATA('echo "clear qlocal(TEST.TRIGGER.Q)" | runmqsc QMESB01') INITQ(TEST.TRIGGER.INIT.Q)
alter qlocal(TEST.TRIGGER.Q) PROCESS(self.clear.queue)
display qstatus(TEST.TRIGGER.INIT.Q)
3 : display qstatus(TEST.TRIGGER.INIT.Q)
AMQ8450: Display queue status details.
QUEUE(TEST.TRIGGER.INIT.Q) TYPE(QUEUE)
CURDEPTH(0) IPPROCS(1)

Hello,
How to reset the trigger for the queue after processing messages other than ALTER QLOCAL script? |

Empty it.
The trigger will fire again the next time the depth goes from 4 to 5 (in your example).

With TRIGTYPE(DEPTH), triggering is turned off when TRIGDEPTH( ) value is reached. It is up to the application to MQSET triggering back on for the queue.
