Take a look in the Sys Admin Guide. There is a whole chapter about handling messages in the DLQ.

also check out the suppport pac site. there is a support pac for deadletter handling.
Or check out CapitalWare site for some stuff.  |

| If you simply want to discard them, consider putting an expiry on them that will get them thrown away as they expire (which is a good thing to consider for all messages). |

Perhaps my memory is rusty, but setting an expiry on dead letter messages will not prevent the dead letter queue from filling up. Because expired messages aren't actually removed from the queue until an MQGET is issued that would have otherwise retrieved it, you can have a queue full of expired messages. As long as there is no application doing MQGETs (browse or otherwise) against the dead letter queue, it will fill up.
right?

You are correct about having to try a MQGET to actually get rid of the message. I figured that if you were worried about these messages that somebody would be looking at the queue often enough to throw them away.
However, I believe that there is a zOS parameter that you can specify that says how often to scan looking for expired messages. I guess I could claim that I was talking about zOS....  |

I guess it's ALTER QMGR EXPRYINT(n) that Bower is refering to.
http://publibfp.boulder.ibm.com/epubs/html/csqzaj09/csqzaj090p.htm#HDRALTMMS
But it's only available on z/OS, but it's quite simple to check for expired messages:
| Code: |
mqconnect
Query local-queues
do while more queues
mqopen
mqget (with msgid=MrMQ, corrid=MrMQ a non used combination)
mqclose
end
mqdisc |
So such a routine shouldn't be so difficult to write...
By the way zOS or in Danish z/OS is just another name for a stable web-server, no big deal.
Just my $0.02
