be to just let MQ to prioritize the messages in some
queue with MSGDLVSQ(PRIORITY) and transactionally forward all messages to an
additional queue with MSGDLVSQ(FIFO) from where my application could then work. For
performance reasons I think it is probably better for this new forwarding application
Pavel,
I'm not entirely sure I understand this priority vs. FIFO delivery dilemma,
so I'll just skip to the questions.
1. If you choose to trigger the forwarding application, it certainly is a
reasonable choice.
2. But, given the second question, the restriction of forwarding messages
due
Pavel,
If I understand you correctly, you would deliver the messages first to a queue with
MSGDLVSQ(PRIORITY) which triggers a job to them move the messages to a FIFO queue.
The only problem I can see with that is that, unless the triggered job is r e a l s
l o w, or unless you trigger
slots and then continue forwarding. While it would wait,
arriving messages would be piling on the first QUEUE in the order according to their
priority, so that they would go to the FIFO queue in this order, too). Would this work
as I think it should (i.e., obey the priority, except for maybe last 10
Peter,
The MQMD-Priority is used by MQ to decide the order in which to send
messages to IMS; they are all queued at the same priority within IMS. I'm
not aware of any priority system on the IMS message queue; even if it
exists, the MQ-IMS Bridge does not take advantage of it.
I suspect

Simple way to look at it. MQ provides services to CICS so if CICS is
running at a higher priority then it keep pre-empting its service provider.

We run the MQ at a higher priority than the CICS regions, but below the IMS and DB2.
