Now, I will mgrate our Application Server from AIX to HP-UX. I was puzzled by a terrible trouble.
the The Server is started naturally, but JMS cannot receive messages.
the Messages are blocked up in the MQ. On the AIX, JMS can receive messages normally. why? the configment is same on the two OS.

Does the WAS log indicate that it has bound the MDBs during startup?

| Also, you can issue qstatus to see if the MDB is listening to your queue |

Do you have a backout threshold on the queues ?
Is your reprocess # > BO threshold ?
Do you have poison messages on the queue?
In case of a poison message the MDB simply shuts down....
Enjoy  |

The trouble is solved!!
the reason is:
MDB started normally,the listernerPort shows the connection is natural,
but the target queue's property IPPROCS is 0, it truelly tells that the listenerPort does not connect to the target queue.
After I delete the ListenerPort and rebuild it, the System began running naturally.
Thanks all!!
