Hi ,

Can you please advise me regarding good criterias for creating separate excution group rather than using same execution group while deploying many message flows.

I'm specifically interested in terms of broker 8 where I believe we can have application level isolation in same execution group.

Also how is this selection depends on memory or jvm heap size requirement etc.

Is there any way(command/GUI) to allocate specific memory to each execution group/message flow/thread within an execution group.

Regards.

The Info Center has specific information on controlling the memory used by the EG process, both the stack and the heap.

There are many many different schools of thought on how to divide message broker solutions across message broker implementations.

The only one who can tell you the one true answer is the one true Scotsman.

If there is a way to do this (and there is), there is no need to do it. The default values work extremely well. If you examine the performance reports for WMB 8, you will notice a well-oiled machine out-of-the-box. Why would you want to mess that up?
