This sounds very confused.
Assuming you mean a remote queue as the 2nd queue, then you cannot determine if the final destination queue is full when putting the message.
De-coupling means that your application should not have awareness of this. MQ will not lose the message, it will be sent to the DLQ.
Operational procedures should be in place to monitor the DLQ and take actions necessary. Also monitoring queue depth may be advisable but these are not application issues.
Don't design applications to have awareness of the MQ infrastructure. |

Only if the 2nd queue is hosted by a different queue manager or you've written an exit (which isn't really part of the queue manager).

Exception added where? On a message? On the queue that is apparently full but has room for an exception? What exception? What error code? If you've set the message to be non-persistent it could well disappear. If not, it could just be somewhere you don't expect.

If you've bought MQ software then presumably you don't want your program to know what's happening with the message; it's the point of WMQ. Also in a well-configured WMQ layout messages won't go missing or be undelivered without the administrator knowing. But again, the administrator will find out not your program. Your program shouldn't care.

I get the impression that no-one is listening to the good advice given.
Define a DLQ and MQ WILL NOT LOSE THE MESSAGE.
Make the received queue maxdepth adequate - what is the problem here? |

Exactly how is the message copied by the queue manager from queue1 to queu2?

WMQ makes messages disappear only if you allow it. When you say "disappears" what you mean is "not on queue2 where I expect it". Have you checked the dead letter queue, transmission queue, failure queue (if defined) and made the usual checks.

I'm not going to dignify that with an answer. Check the documentation.

Yes - don't put it from your Java program.
