Hi
Currently using java program i am putting the message to my remotequeue.From there it will reach the remote system.
But my requirement is after reaching the qmgr RemQ, i need to write the message to one place in MQServer itself.
Basically i need to trace IN and OUT message to MQServer itself.
http://www.developer.ibm.com/tech/sampmq.html
From the above path i was down loaded one prg mirrorq.c ,Is it available on java ??
can anyone suggest any other ideas
regards

Api exits only get executed in the MQ Server processing the MQ API call, so these samples will work just as effectively there when a java pgm is putting the msgs.
I assume COA/COD doesnt help you? |

| I'm not sure that I understand what you are asking. Do you want to know all of the messages that go into/out of a qmgr through a given channel? If so, this sounds like something you'd put in a channel exit. |

Hi Bower
Thanks of ur Reply
Currently our Application scenerio is like
Applicaiton A is putting the message(using java prg) to LCL Q.Application B is reading the messgae(using JAVA) and it is putting the Reply another LCL Q.Again Application A is reading the message using the CorrID match concept.
Here problem is.......it is working almost fine,But recently i had a problem Application B has put the message to LCL Q.Application A was not received that message.
After this problem i am planning to write the all IN and OUT messages from the queue.
1.How can i do the above requirement??
2.Is it possible to trace the old message from Qmgr?
3.Any other suggestion ..
regards

| I can't say that I've seen MQ lose messages. It sounds like your situation is only dealing with local messages. You could look into the other version of mirrorq (the one that uses triggering) to copy your messages somewhere. You could also check your dead letter queue to make sure that the message didn't get there. You might also look into the COA/COD type of options. I'd also suggest that you walk through your programs to make sure there isn't a path where they might get a message and inadvertantly throw it away. Also, double-check that there is error handling for the put not working. Logging all of the message traffic to find a missing message sure seems like a lot of overhead. |
