Thanks.

I was thinking of the Oracle executable on Windows2000.

 << File: Card for Don Jerman >> My understanding is "according to design" it should do it automatically. My
experience is it does, sort of. But the app has to be multi-threaded (by the OS
definition, not just context-mapped like Java green threads) for it to ever use
more than one processor at the same time. If your single-threaded then for obvious reasons NT will tend to give the next time-slice to the same processor
if it's not busy, so it looks like you're stuck on the same one much of the time.

With the task manager you can set "processor affinity" on MP machines from the
right-click menu of the process. This limits which of the N processors will be
used to schedule your process. So you can limit one processor hog to 1 or 2 processors and let the well behaved programs run freely on the others. I don't
know how to do this using non-gui tools or to set it up at start time, and your
userid has to have permission to do it (essentially you have to be running as
the process owner). But it's a starting point for research :).
