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 on depth, the messages still arrive in the FIFO queue in the same order they arrived on the PRIORITY queue. This is because the QMgr can't sort the messages by priority unless they are allowed to first build in the queue. You didn't mention whether your app would trigger on depth or not so maybe you considered this already.

I figured out that the most rational way to meet it would 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 to be server application. For the administration convenience and robustness, I think it might better be a triggered process rather than a standalone daemon. I need help with two questions: 1. Does my solution outlined above make sense? Especially -- what are pros and contras and gotchas for making it a triggered process (I have never written one before)? 2. Isn't there something around ready, like a service pack for doing this type of work? One requirement I feel I will have to consider is that the second queue must not be deep, otherwise, if the downstream process takes too long, the messages of different original priority will pile up in the secondary queue and the client will not be sastisfied with how we actually obey that original priority. So, the solution must properly process the "destination queue is full" condition.

I've just tried it from http://www-1.ibm.com/support/docview.wss?rs=203&uid=swg24000142&loc=en_US&cs=utf-8&lang=en and it seems to work fine for me. Cheers, P.

N.AC.AT> 20/07/2004 15:00 Please respond to MQSeries List Hi.... After having read so many positive things recently about the MO71 support pac, I decided to download it and take a look. But of course, it is never that easy :) As I am trying to download it by clicking on the link, I get the license acceptance window which I respond to "accept", then I get a "Not Authorized" page ?!?!?!?!?!??!?!? I have only done this about a million times over the years (although it has been a while since the last) and never had this happen. Has something changed that I missed?!? Any clues about what I can do to download this support pac?!?!? Thanks....
