If you do not receive a reply

If you do not receive a reply to your request message, work through this checklist:

• Is the command server running?

• Is the WaitInterval long enough?

• Are the system-command input and reply-to queues correctly defined?

• Were the MQOPEN calls to these queues successful?

• Are both the system-command input and reply-to queues enabled for MQPUT and MQGET calls?

• Have you considered increasing the MAXDEPTH and MAXMSGL attributes of your queues?

• Are you are using the CorrelId and MsgId fields correctly?

• Is the queue manager still running?

• Was the command built correctly?

• Are all your remote links defined and operating correctly?

• Were the MQPUT calls correctly defined?

• Has the reply-to queue been defined as a temporary dynamic queue instead of a permanent dynamic queue? (If the request message is persistent, use a permanent dynamic queue for the reply.)

When the command server generates replies but cannot write them to the reply-to queue that you specify, it writes them to the dead-letter queue.
