Hi All,

I got a question from my client !!!

what is the Maximum amount of memory that your message broker can hold???

apart from the queue depth (100 MB).


Env: Win2000; Message Broker 6.0 ; Message Queue 5.3.

This depends on the number of execution groups.

I've seen max about 300 Mb used by one execution group, and about 2 Gb used by broker with 9 execution groups.

To my knowledge,

On a Windows Machine, Maximum amount of memory that message broker can hold is 2GB.
If that limit is exceeded, there is a definite chance of failure.

It obviously changes if you are using 64bit execution groups on a 64bit machine.

Remember that the only processes that really use memory on a Broker are the Execution Groups, and they are each individual DataFlowEngine processes - so they can each use different amounts of memory.
