Hi Ray.
I tried your script on some of my images. Works fine, except when Oracle is
involved.
linux62:~ # ps -eo pmem | awk '{pmem += $1};END {print "pmem ="pmem"%"}';
pmem =1347.1%
I do have a lot of swap blocks allocated. This is due to a batch type run,
that is run off hours. During the day, when users are on, we swap very little.
So if this does include swap pages, I don't think the script would give me what
I need, during normal processing. Do you agree? Or am off track here?
Thanks

Start up all your Linux procs and then run this little script.
#! /bin/sh
ps -eo pmem | awk '{pmem += $1}; END {print "pmem = "pmem"%"}';
It will give you a ballpark percentage of current memory utilization.
I tuned some Apache/ftp servers down to 100M with no ill effects.
