Hmm, I just got this information from our IBM business partner. Looks like a good presentation on how to configure and monitor an AIX 5.3 system for performance:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Jaqui Lynch authored and delivered the "AIX Performance Tuning" session at last month's Technical University conference. Download her presentation from: http://www.circle4.com/papers/pseries-a26-aug06.pdf These tuning parameters are rules-of-thumb for general commercial applications.

That is what I was looking for but it did not contain what I wanted. A few years ago, when I was on AIX 5.1, there was discussion on this list about vmtune, now vmo, maxperm and minperm settings to improve TSM performance on AIX systems. Is there any IBM publications that makes recommendations for these settings? Are the settings we discussed in AIX 5.1 days, i.e. maxperm=40, minperm=10, still valid for an AIX 5.3, TSM 5.3 system? David >>> "Prather, Wanda" <[EMAIL PROTECTED]> 10/24/2006 11:19 AM >>> The Perf Tuning guide isn't platform specific. Go back to the Information Center, its under the very long link for Storage Manager Messages, Problem Determination, and Performance Tuning. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of David E Ehresman Sent: Tuesday, October 24, 2006 11:08 AM To: [email protected] Subject: TSM 5.3 Performance Tuning Is there a TSM 5.3 Performance Tuning guide (for AIX 5.3)?
