Dead Letter Queue (DLQ) holds messages that cannot be delivered for some reason. Each message on DLQ has a Dead Letter Header (MQDLH), which will have information about the error.
Hope this helps.

Thanks for the answer. I have other questions about the Dead Letter Queue. How do I declare the Dead Letter Queue ? as a normal Local Queue ? How does the Queue Manager Knows which of the Queues is the Dead Letter Queue ? o How do I tell the QManager that ?
Thanks in advance |

And you can write (or obtain) special programs called dead letter handlers (MQSeries ships with a sample one) that will reprocess messages on the dead letter queue...

Depending on your platform it would something like this
runmqsc
alt qmgr DEADQ(DEADQ.NAME)

Excellent, I hadn't seen the Qmanager's attribute for the Dead Letter, Thanks a lot, this is a great Group. Is there an official mailing list for this site? I found one on Yahoo Groups but if there is one list on this site would be great .
