We are running WAS5.1, pub/sub MDBs and MB5.0 On a subsequent starts of WAS application, I get the exception, in summary saying that Subscription is already in use and cannot be updated, and it prevents the start of the ListenerPort.

thank you

P.S.

at the end of this exception stack, I am including another exception from the WAS log which comes up at the very beginning.


Here is the complete exception:

Does that have to do with changing dynamically in JNDI the underlying queue of the MDB while WAS is running ?

MDB are very stable animals. Do not change the setup while WAS is running.

If not it says it right there in the startup: The port you are using for the MDB is already taken. Get yourself a different port for your MDB setup!

if I could ask you a clarification question as you seem to know what is going on in there ...

Does your suggestion mean recreating the ListenerPort?

How can change the port otherwise?

And where did you see a message suggesting that a port is already taken?

thank you in advance

Verify that the MDB ListenerPort is unique for each MDB.
Verify that the ID supplied when accessing the Topic is the same as the one that created the subscription.

There were some nullpointerexceptions that were fixed in various CSDs. What version of the WMQ code are you running (use mqver)? Also, are you using embedded JMS or full WMQ?

Coud be as well that he declared multiple instances of the MDB on a queue that's opened in "Exclusive" mode...
