Page Faults - Anyway to reduce SAP Storage to Reduce Page Faults

What is your MAXACT setting for *BASE POOL?
Our config is very similar with 2 app servers & all users on them also
Without knowing anymore details; sounds like your MAXACT is set too high
BUT
That is something that you would have to play with and observe impact to the
performance over time for each change made

Below is a snapshot of our DB pool config
MB Reserve MAXACT
1 879.32 586.30 +++++
2 11358.67 .08 200
3 50.00 .00 2

Our DB Server is a 9406-730 with 13gig memory. We have all users
logging on to two app servers, we try not to have any users on the DB
server. Our DB server 3 memory pools, *Machine=1gig, *base=11.9gig,
*spool=.1gig. We basically have 12gig in *BASE which runs SAP. Our
Non-DB page faults average 200-400 per second (via wrksyssts) and
will sometimes peak 1000-2000 per second. I've read in various notes
and manuals that the SAP memory definitions such as Program Buffer,
Paging Area, Extended Memory, Number of WP's do not affect System
Performance. Is this a true or did I just misunderstand what I've
seen? Are there SAP buffers or other setting which I may have
oversized and is causing the high Non-DB page faults? The sizing
tools we've used indicates 12gig should enough. Before we go and
purchase more memory we'd like to know if something can be cahnged to
reduce the amount of memory we are currently using. How much memory
are others running on the DB server?
