vmstat, comments and advices needed

Hi all..

I need some comments or advices about my HP-UX 11.11 performance.
It runs Oracle, some apps and weblogic.

For several times in a day, it's performance drops poorly (approx for minutes until an hour).
I tried to find articles about unix, oracle and weblogic tuning, which leads me to some informations :

1. Some Unix Kernel configuration (max_thread_proc, maxfiles, maxusers) needs to be set larger than the default configurations (I will reconfigure this soon)

2. My kernel configuration : lotsfree, desfree, minfree sets to 0 (zero)
I found some article which told to set it, according to my memory size. Anyone tried this before? did it give you a good result?

3. I ran vmstat for about 10 minutes (@1 sec), which gave me this results :
- SR : 20% return large page scan rate (avr. 9k, max 60k) and 80% return below 200 pages (most articles say this is not good, needs more RAM)
- RE : 20% return large reclaims (arg 800, max 4k) and 80% return below 10 pages
- R : 4% return more than my CPUs count (avr 10, during large SR) and 96% return below my CPUs count
- W : 5% return avr 15 pages, and 95% return almost none
- and PI also increase while RE increase

I need some comments or advices about 3 points above,
and, is it just configuration problem (tuning problem only) or I 'extremly' need more RAM?


(I'm kinda new at this, need much advices and guidances)
Thank you for your time, comments and advices.
