In this site:
http://pic.dhe.ibm.com/infocenter/wmqv7/v7r5/index.jsp?topic=%2Fcom.ibm.mq.ref.adm.doc%2Fq083500_.htm
It says that
| Code: |
| They are deleted when an application (not necessarily the one that issued the MQOPEN call that created the queue) successfully closes the queue using the MQCO_DELETE or MQCO_DELETE_PURGE option. |
My question: If all of the applications that have opened the queue sudenly terminate, without any one of them clsing with the MQCO_DLETE or MQCO_DELETE_PURGE option (they all simply terminate with closing with these options), will the Persistent Dynamic queue persist, or will its life end
Thanks |

Not convinced that's the link you think it is.

| Code: |
They hold persistent or nonpersistent messages.
They are recoverable in the event of system failures. |
Both of these things would be impossible if the queue disappeared when nothing was connected to it.
Please do a little more research before posting these little questions.

For purposes of clarity and precision:
Dynamic queues come in two flavors, namely: Temporary Dynamic Dynamic and Permanent Dynamic. The title of your OP
| Quote: |
| Persistent Dynamic Queues (life cycle) |
incorrectly refers to the Permanent flavor as persistent.
Temporary Dynamic queues can only hold non-persistent messages, while Permanent Dynamic queues can hold both non-persistent and persistent messages.
Temporary Dynamic queues cannot live beyond the life of the application, while Permanent Dynamic queues can live beyond the life of the application. All of this is clearly explained in the InfoCenter and APR and APG manuals.
