For know the how many phisical memory (RAM) is used, i have executed
the following script

#!/usr/bin/sh
# AIX 5L

#set -x

clear

RealMem=`bootinfo -r`
MeM=0

for i in `ps -edf|awk '{print $1}'|sort -u|grep -v UID`
do
svmon -U $i|head -n 4 >> /tmp/DispMem$$-2
done

cat /tmp/DispMem$$-2

for i in `cat /tmp/DispMem$$-2|grep -v "User"|awk '{print $2}'`
do
MeM=`expr $MeM + $i "*" 4`
done

echo;echo "\t********************"
echo "\tTotal ... "${RealMem}"k"
echo "\tUsed .... "${MeM}"k"
DifMem=`expr ${RealMem} - ${MeM}`
echo "\tFree .... "${DifMem}"k"
echo "\t********************";echo

rm /tmp/DispMem$$-*

But i find that the real memory used is great than the phisical memory
(RAM bootinfo -r).
The negative value for free it is allocate to disk (virtual memory) ??

Thank you

Perhaps your math is incorrect. In any event, it may
be easier to build some automation around nmon.
