As far as I know you cant set processor affinity under NT however you can
set priorities for processes and tasks. You may want to try setting you MQ
processes with a higher priority than MQSI(WMQI). After all it is WMQ that
is servicing WMQI and as such you want it receiving priority.

Please respond to
MQSeries List
When MQSI is doing its thing and is real busy with heavy volume going thru
an ESQL heavy compute node, the MCAs on the box get left with no resources.
As a result we see XMIT queues to this box temporarily back up as the
sending MCAs can't talk to the receivers, because the receivers have no
available CPU.
On a 2 CPU box, I would like to say, CPU#1 is only for MQSI, and #2 is for
the QM and its MCAs.
But maybe if there were 2 or 4 CPUs all going at the same time, the issue
would not crop up anyway.

Maybe I don't see your point, but doesn't that negate the benefits of
Symmetrical Multi-Processing? Don't do for the operating system what the
operating system will do for you.

If you had your MQSI flows running on a server that had multiple CPUs, is
there away to assign Execution groups X, Y and Z to CPU #1, Execution group
A to CPU #2 and the remainder of the execution groups to CPU #3? If there
was a fourth CPU, would there be a way to say that all the regular QM
processes ( MCAs, etc.) should use just this CPU?
And the RAM would be equally shared by all regardless, correct?
