Hi all,
I am creating qaliases to reference a local Q and I ma wondering if the qalias that was used is located anywhere in the message header. I looked at the message with amqsbcg but I did not see the qalias anywhere. Is it possible to get the qalias used once the message is on the local queue? I am trying to cut back on the number of queues needed.
Reason that I am asking is that I've got 1000 queue managers connecting to my cluster and 10 queues per QM so I am trying to lighten the load by aliasing all 10 to the same queue. But I need to be able to distinguish which queue alias the message came from. |

QALIAS is just a nick name and its not a real queue, it can point to another queue which should be a Real queue
it wont present in the Message header.
mainly QALIAS is used to hide the details of main business/application queues (in order to avoid Accidental deletion or corruption of the queues)
AFIK you wont get the QALIAS name from the local queue

| What about when the application is putting the message to the queue? Do they have the option of specifying any additional information in the header like message format? |

Today you could do that from an application by using an RFH2 header, but not all receiving applications can properly handle an RFH2 header.
If you hold on a little longer, 2-3 weeks from now...
V7 will be available and this can be addressed but still needs to be explicitly coded in the application by using Message Properties 
I have not tested this yet, but I believe message properties will be "lost" when mixing of V7 with V6 environments occur.

You can configure it so that it automatically converts the properties into an RFH2 when downshifting to V6.
