Dear all experts
MQ version 5.3 fixed pack 9 installed on Window 2003 server
Queue Manager and Channel put all undeliver message into dead letter queue call QM.CORE.DEAD.LETTER.QUEUE

I am afraid it will be fill full in future. I don't know clearly what i must do?

I think that: "I will using trigger , when a message come to QM.CORE.DEAD.LETTER.QUEUE trigger will start and log it to a file error.log
then this trigger clear this message."

is this ok? if it OK how i can clear it?

I assume this is the "normal" dead letter queue assigned to the queuemanager.

If you have messages in the dlq then there is a problem somewhere, in most cases on your local queuemanager, e.g. a non existing queue, a full queue, a put disabled queue, queue type mismatch, wrong target queue information supplied by the message sender or lots of other reasons that makes it impossible for mqseres to deliver the message to the target queue.
You should check the dlq header of the messages in the dlq to investigate the reason and fix the error (use a browse program, mq explorer, mo71 , .....)
After that use dle dlq handler program to deliver or delete the messages or just "clear" the dlq if you do not need the messages.

Of course you can also trigger the dlq and file / delete messages with some little programs, but this does not fix any errors.
