Answer / atul sharma

As we know Dead Letter Queue Used for storing the messages
those are not routed or their Transmission Queue is Not
Present OR Queue Manager Down .
We make Rule table for Dead letter Queue by which all
messages are easly routed to there destination queue when
application starts.

Rule Table for DLQ is:- INPUTQM(QMGR NAME) INPUTQ(QUEUE
NAME) REASON(CODE) ACTION(FWD) FWDQ(QUEUE NAME) HEADER(Y/N)

Answer / afroz

DLQ - Dead Letter Queue

If an application tries to put a message to another
application and if it is not delivered then it goes to the
DLQ. So DLQ is nothing but all undelivered messages stored
in DLQ.

Alterenate Defination:
The dead-letter queue is a local queue where messages are
put if they cannot be routed to their intended destination

You need to create a DLQ at the time of creating a Queue
Manager.

crtmqm -q -d MY.DEFAULT.XMIT.QUEUE -u
SYSTEM.DEAD.LETTER.QUEUE SATURN.QUEUE.MANAGER

where -u is dead letter queue

Hope this Helps
