Hi
We are using websphere MQ 5.3 and Mercator Integration Broker on AIX environment. We will be enabling the intercommunication between AIX and AS - 400 queue managers .I have a question related to MQ Design issue.
Our Production Queue Manager(AIX) is going to host 62 Application Local Queues,where messages will come from regions. Below are the regions from where the messages will orginate,
1. Europe region will have 20 Application Local Queues
2. United Kingdom region will have 10 Application Local Queues.
3.America region will have 6 Application Local Queues
4.Singapore (SBCS) region will have 10 Application Local Queues.
5.Singapore (DBCS) region will have 12 Application Local Queues.
6.Australia region will have 4 Application Local Queues
1.Can we reduce the number of Application Local Queues to region wise, there by introducing the Alias Queues? If yes what will be the implications on the Application(here it is Mercator) which is retrieving the messages ? 
2.Is it feasible to have one BackOut Queue for the whole application or one Backout queue for each application Local queue?
3.Which is the best mechanism to move messages from Backout Queue to Application Local queues for re-processing?
Please do give some tips and suggestions for implementing the same
Thanks and Regards
N.Satish

Hi.
I don't know Mercator, but an analogy to WMQI:
1) You can design one queue per region, at least, and a "process" or "flow" would read and decide what to do with the message (supposing you can make decisions based on messages!). You don't need alias queues.
2) You can design a BOQ for each region also.
3) A "process" dedicated to read BOQs and, based on content, redirect to the pertaining "process"/queue.
Hope it helps more than confuses!

Hi
Thanks for the inputs Miranda
Already AS-400 Queue Managers has remote queue defnitions pointing to these local queues. I dont want to distrub the existing setup. So i thought of using Alias queues pointing to application local queue/region.
Because if i am not using this approach , i have to define 62 Mercator Listener Maps ,each pointing to one application queue. It is really difficult to maintain in the production environment.
Any Suggestiona Miranda
One more thing , What is the optimal value for setting the Backout Threshold ?
Thanks and Regards

Hummm... not sure now.
Maybe in case you would like to treat errors by different handlers... so you can group errors by "region queues" !?!

You can use qmgr alias queues, one for each qmgr and that would eliminate your qremote definitions.
