Home -> Community -> Mailing Lists -> Oracle-L -> RE: AIC MEMORY CHECK
I don't think "sr" greater than 0 mean there is memory problem *always*. Yes
"r" is the better place to check if your system is cpu bound or not.

I would say you need to pay attation to " sr, po, pi" columns.
This question is not so easy to answer in UNIX systems.
There is good paper "The SolarisMemorySystem Sizing,ToolsandArchitecture"
from Sun about UNIX memory architecture concepts. If you have time take a
look.
I would say, first of all you need pay your attention to “sr” – “Pages
scanned by page-replacement algorithm”.
If you have this figure not 0 for a long time then your system is out of
physical memory.
