IBM i: Recovering your system: SC41-5304: QMCHPOOL size



fixed

I propose an update to the manual for IBM i entitled "Recovering your
system", SC41-5304.

In there is a section which goes:
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. For a
more precise setting of the
QMCHPOOL system value, see the Types of memory pools information center
topic.

According to:
http://pic.dhe.ibm.com/infocenter/iseries/v7r1m0/topic/rzamp/rzampother.htm
"Minimum memory per partition" is 256MB.

I propose changing this section to:
As a general rule change the QMCHPOOL system value to be 15 percent of the
main storage size. For a more precise setting of the
QMCHPOOL system value, see the Types of memory pools information center
topic.

If IBM also chooses this time to review this and change the percent
recommended then more power to them.
