How about using the new features of V8 and forcing the expiry?
Or if the application was JMS and the queue was in the properties file, redefine the queue in the URI form with near immediate expiry of the messages...?

This thread was also posted on the MQ LISTSERV, and Paul Clarke mentioned that just doing the following could be done:
| Code: |
DEFINE TOPIC(NULLTOPIC) TOPICSTR('.NULL.') SUB(DISABLED)
DEFINE QALIAS(NULLQ) TARGTYPE(TOPIC) TARGET(NULLTOPIC)
|
When your applications PUT to the NULLQ, they will go to a topic with no subscribers, and then be discarded. I wish I had known about this, before I wrote a COBOL program this year to basically do what Roger had coded with emptyQ! 
P.S. - We do not use PUB/SUB, so I may have messed up some of the PUB/SUB terminology, above.
