Prem, It is good that you have found the solution. I have read mentioned article, and it is looks that svmon is the right tool for your purpose on AIX. BWT: > One such tool is "svmon". This program can be located on the IBM AIX CD-ROM > as part of the AIX fileset "perfagent.tools". Use the command "smit install_latest" > to install this fileset. ?svmon? not installed by default I have checked some boxes. Looks like additional tool which AIX dev kindly provide. Thank you for sharing useful information.

Hi Velikanovs, I am not much ware of "UNIX virtual memory mechanisms" . but the AIX coomands metalink docs suggest are: ps v svmon IIR, "svmon" is the one u r looking for. and in case of "ps v" RSS - TRS -> gives u the private memory used by a process. <QUOTE> The RSS number is equal to the sum of the number of working-segment pages in memory times 4 and the code-segment pages in memory times 4. The TRS number is equal to just the code-segment pages in memory times 4. </QUOTE> Doc 123754.1 says so.Is that not right ? i am not sure about it.
