RE: Subsystems

Steven,

I can see a few valid reasons, what does your boss wish to accomplish?

Here are some reasons:

- You have a group of workstations which require consistently better
response times than others.  I have done this at a firm which had a very
tight payroll entry window.  By configuring the subsystems, these jobs
could have a higher priority, longer timeslice, etc.  Please note that
this could also be accomplished within the same subsystem by different
means.

- You want the memory hogs to feed together and leave everyone else
alone.  By separating out memory-intense interactive jobs into a
separate pool, other jobs can achieve more consistent response time.

- You have a period of time in which you wish to allow some users access
to the system while everyone else cannot get a signon screen.  You would
do this by shutting down one of the interactive subsystems.

Note that every objective but the last can be accomplished within a
single subsystem.  It may make more sense and be more self-documenting
to use multiple subsystems for the first two, but it is not a
requirement.

Andy Nolen-Parkhouse
