I heard some new features in MQSeries 5.3. One is qstatus that allows us to find who/which open the queue. The other one is qmgr has the ability to index the messages in a queue.
I am wondering how to use the index of the messages if there is this feature. As you know, the queue is a sequential storage object. Compare to tables in DB, we would like to access the messages in a queue randomly. Is there a way to do that and how?
Thanks in advance,
Yannan |

| I remember this subject coming up at one of the MQ conferences. The bottom line was that DBs are designed towards random access and queues are designed towards sequential access. If you need random access, I'd suggest going with a DB. |

There are indexs for either Message ID/CorrelID and you can get with
either. So you could make a database of sorts.

On Z/OS, a queue may be indexed by message id or correlation id.
