Hi folks, I'm a newby (just registered). I'm the lead architect for a new project where the major requirement is to receive on a central site messages form about 10.000 JMS Client speaded al over the Internet. One message a day for each Client which means 10.000 messages a day. I can manage the schedule, so as a guess i can say we should not have more that 5 concurrent incoming sessions. Clients send a zip file, 046 MB in size.
Anyway the question is related on how to design the Front End QManager, in terms of how many incoming queues is it better to define ?
- one queue for all incoming messages ?
- five queues, one for each concurrent session ?
- one queue for each Client (10.000 queues) ?
Any sugegstion is appreciated.

It's probably not as important to limit the number of sessions as it is the number of incoming messages.
46 mg messages are fairly big - so going as low as 5 is not a bad place to start. But doing some performance testing may allow you to raise that.
The question to answer before you figure out how many queues you have on the front end is - how many instances of your back end application can you run at once? How many messages can each instance of that back end application handle in a small period of time (a minute, say).
Also if the back end applications have to process messages from different sections of the clients - region, timezone, business process, etc...
These questions will tell you how many back end queues you need. Then you can figure out how to set up an MQ infrastructure to handle that. Whether you need a cluster or not, and etc.
