I have question here, a remote queue created, but remote queue manager does not started. I put a message to remote queue, check the XMIT Q, current depth is 1, this message supposed to be put into DLQ, beacuse remoet queue manager does not start. but when I check XMIT Q after several minutes, curdepth still 1 and no message put into DLQ.

So my question is:
1. How the MQ decide to put message to DLQ
2. is there some parameter to control how long or how many time should MQ try to send message to remote queue manager.

thanks!

MQ tries to conect to the Remote Q.M for Shot retry interal and Long retry intervel in the channel properties. Then the channel go to Stopped state. I think at this time Mq puts it to the Dead Letter Queue.
You could look in the intercommunication manual for more details

No...MQ is working exactly as designed.

MQ will put messages on the DLQ that are non-deliverable....but just because a remote queue manager isn't up doesn't make the message non-deliverable as such.

You could specify an expiration on the message.

What is your real requirement? In other words, why would you want a message to go to the DLQ?

I just want to learn MQ mechanism, no special requirement.

Two question about expiration.
what it the unit for expiration, seconds ,miliseconds, or something else?
when I use MQ explorer send message, expiration of message is set to -1
what does "-1" mean?

thanks very much
