Memory and Swap issues

[Rafael Gutierrez]

Hi.

Clay, you can see ipcs output in an earlier reply.

After vmstat -z command, I haven't found po greater than zero anymore (I have executed vmstat several times).

I have another question: bufpages=nbuf*2 and nbuf=0 currently, how can I guess nbuf value according to server configuration ?

Thanks, Rafael.

My question for Clay.

If nbuf and bufpages both are set non-zero, then how cache is calculated??

[A. Clay Stephenson]

In almost every case, the default behavior with nbuf set to zero is fine. I would set bufpages as I mentioned earlier and leave nbuf=0.

RAC,

compute it as mentionned here

Thank you everybody. The memory and swap usage is really hard to understand in HP-UX, but it's more clear for me now.
