Hello,
I tried to configure a trigger in MQ Series. Sadly this trigger does not work the way I think it should.
I am using WebSphere 5.3 service level 8 on Windows 2000.
I installed Server and Client on the same win2000 host.
I installed a queue manager named QM_gspc and created to local queues. One named applicaktion.queue and the other initiation.queue.
The queues was created by following command:
| Quote: |
DEFINE QLOCAL('application.queue') REPLACE LIKE(SYSTEM.DEFAULT.LOCAL.QUEUE) DESCR(
'appl queue description') INITQ(INITIATION.QUEUE) TRIGGER TRIGT
YPE(every)
DEFINE QLOCAL('initiation.queue') REPLACE LIKE (SYSTEM.DEFAULT.LOCAL.QUEUE) DESCR(
'initiation queue description') |
I used the api testprogram provided by the installation of WebSphere MQ for putting messages into the application.queue. I supposed that there will be a message created in 'initiation.queue', but when I looked into this queue (using MQExplorer) its empty.
Did I miss something? |

There is a long set of conditions that must be met before a trigger message is created.
The one you are most likely missing is that you have to have a trigger monitor running against the initiation queue, to cause the initiation queue to have an Open Input Count that is greater than 1.

Thank you for your fast answer.
I tried to hold the 'initiation.queue' OpenInputCounter greater than 1 by using the api test program. I simply opened this queue and started a second instanz of this test program and putted message on 'application.queue', but sadly still nothing happened to 'initiation.queue'.
Is there any way to test this, without implementing a trigger monitor or is there a simple one already supplied by WebSphere MQ? |

There is a simple trigger monitor already supplied, called runmqtrm.
The syntax is
| Code: |
| runmqtrm -m QMGR -q INITQ |
The app runs in the foreground, writing status messages to its concole.
I did notice a problem in your definitions. The local queue has a the INITQ attribute defined as INITIATION.QUEUE, but you have defined the queue with a name ''initiation.queue'.
Correct your queue defs, so that the INITQ attribute on the app queue matches the name of the defined initiation queue
Run the trigger monitor as above. |

Thank you for your answer.
I tried it out and corrected my queue definitions for using all queues with uppercase letters.
I started the trigger monitor you mentioned by typing:
| Quote: |
runmqtrm -m QM_gspc -q INITIATION.QUEUE
|
Then I tried to put some messages with the api testprogram into 'APPLICATION.QUEUE', but nothing happened to the 'INITIATION.QUEUE'. Also the console with the trigger monitors gaves no additional output.
Output of trigger monitor:

You also need to define a PROCESS, and assign it to the triggered queue.
