AIX 5.3
4 GB RAM
2 GB swap

Using svmon, I see that I have 25 MB of free memory
Using lsps, I see that I am using 18% swap

Is there a way that I can identify the process/processess that are using swap?

Thanks!

Try svmon -P.

Unfortunately, I have over 100 processess running....

Is there another way?

If not, what am I looking for in the output that would show me
that the particular process is in swap?

Thanks!

Take a look at the svmon manpage. svmon -P <pid> might get you what you need. At least it'll narrow down your list to the PID(s) you have questions with.

OK

I used svmon -P and through grep, awk and expr, getting "pgsp" value,I determined
that 2.9 GB of swap was being used...

I only have 2 GB

Nobody says the AIX VMM is easy to understand - I'm quite often confused still. Here's from svmon manpage.

A segment can be used by multiple processes. Each page from such a segment
is accounted for in the inuse, pin, virtual or pgspace fields for each
process that uses the segment. Therefore, the total of the inuse, pin,
virtual and pgspace fields over all active processes may exceed the total
number of pages in memory or on paging space.

I thought it may be more complex than a simple set of commands...

The more I use svmon, the more confused I get...

Once, I got a value for one process "Inuse" of 47 GB

My RAM was 2 GB
My swap was 4 GB

Go figure....

Thanks!

Try the following :

1) ps gv | head -n 1; ps gv | egrep -v "RSS" | sort +6b -7 -n -r
( SIZE—The actual amount of paging space allocated for this process )

2)svmon -P | grep -p PID

You're on the right track. Use svmon like this:

svmon -P <pid>

In the output, you'll see a column up top called "Pgsp"; this will
tell you, in 4K pages (assuming the process doesn't use larger pages)
how much paging space that particular process is using.
