Thank you for your reply. I do not know if you saw the script or not, but I use "svmon -C" which counts normally once the shared segments for all the processes runing the command passed in parameter. I do that for all commands run in the system and then I sum the "virtual" colonne obtained for each command. what is wrong with that ? Do you have another solution ? I really need help. Thanks again.

Didn't I answer this last week?Your script is wrong. The figure you are using includes all of the shared memory. i.e. Pages of memory used by more than one process. Therefore you are counting these pages more than once and you will inevitably end up with an inaccurate figure.

Subject: Urgent : total memory usage
Hi all,
AIX 4.3.3
I writed the following script to estimate the total memory usage by all processes in the system based on the "virtual" colonne of the "svmon -C" command, but the result returned is always greater than the size of real memory (bootinfo -r).
Is that normal ? Did I miss something ? I really need your help.
