RE: Why separate pools?

[rob@xxxxxxxxx]

We do have a couple of machines where we still run under QBASE instead of 
the QBATCH/QINTER/etc combo.  However the most 5250 users is 1 or 2, 
systems department staff only.  And about the only QBATCH type job is the 
nightly backup.  Primarily Dedicated Servers for Domino and that genre.

RE: Why separate pools?






Probably, but as easy as it is to separate the two (and assuming you are 
not
memory constrained) why take the chance?  The first thing I was ever 
taught
about performance was to group like workloads.  I don't believe that you
need a separate pool for every subsystem or a separate subsystem for every
10 users, but it's relatively easy to separate batch from interactive and
base.  Why wait for a problem to manifest itself?  (Besides, if your users
are like mine they'll be screaming to VP's long before we would notice a
problem...)

But won't the job also yield as soon as it goes into a long wait? 

And since IO is a long wait, unless you're calculating something very
complex that doesn't include IO (SETI@HOME?) the batch job will yield
LONG before it eats up it's time slice, no?
