Hello, Thank you ... swapinfo in SAM shows Avail=Used=1024 Mb whereas swapinfo -tam is different .. Any idea if this system is out of swap space or SAM has a bug? The patches doesn't speak about swap in SAM ..

This is the swapinfo -tam:

swapinfo -tam
Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 1024 0 1024 0% 0 - 1 /dev/vg00/lvol2
reserve - 1024 -1024
memory 1508 697 811 46%
total 2532 1721 811 68% - 0 -

You don't appear to be using any swap.

That is usually a good thing.

How about some vmstat or sar analysis(script attached).

Hello Steven, Thanks ..

vmstat doesn't show any po (paging ...). Sorry, sar gives me an error right now ..
sar: Can't open /var/adm/sa/sa14

Can you clarify if this system needs more swap? When would it require?

How much RAM does the system have?

You *MUST* have at least as much swap, of one form or another, as you have RAM.

You do have the swapmem_on kernel parameter set to 1, so the system will use a number equal to about 75% of your RAM size (this is called pseudo-swap) and add it to your available swap space to make the system think you have more swap than you really do.

In your case the pseudo swap is 1508 MB. Your device swap is 1024 MB. If the amount of RAM you have is greater than 2532 MB, then you need more swap.

I suspect that you have 2GB of RAM in this machine. Judging from your swapinfo output you are OK. No need for any more swap space.

sar is working correctly. You must tell sar the measurement period as a minimum or it will assume you want to extract data from a previously recorded data file (see man page). To look at 1 second of CPU usage: sar -u 1
To repeat 10 times: sar -u 1 10

Always use sar with a measurement length.
