RE: Recovering your system - QMCHPOOL



fixed

Production LPAR is 196gb, machine pool is currently 22gb, 15% would be 29gb.
R&D LPAR is 40g, machine pool currently 2gb, 15% would be 6gb
Upgrade partition is 6gb, machine pool currently .5gb, 15% would .9gb

Should I consider adjusting the machine pools upward?
Not having any performance issues.

Sue,

Thank you for looking up that information.

Since the minimum memory per partition is 256MB, then this:
As a general rule, if the main storage size is 64 MB or larger, change the QMCHPOOL system value to be 15 percent of the main storage size. If the main storage size is less than 64 MB, change the QMCHPOOL system value to be 20 percent of the main storage size.

should be changed to:
As a general rule change the QMCHPOOL system value to be 15 percent of the main storage size.

In all editions of the "Recovering your system" manual, 7.1 and on?

The only caveat being that this would be a good time to review this general recommendation since it's a bit dated.
