These are the commands I use:
1) svmon -Put 10 | more
The top line will provide you with all the info you need, and it will list your top 10 (oracle) memory hogs
FYI...(Inuse / 256) = MB (approximate)
2) ps vg | sort +r +5 | more
Sorts on the SIZE column, then you can use the PID to find the offender (oracle) - notice there is no '-' in front of the vg...very important
3) ps aux | sort -nr +3 | head
Lists the %MEM column - +2 lists %CPU. Again, no '-' in front of the aux.
Hope this helps;
Theresa

I usually do:
ps auxwww
and then sum up the "RSS" column. Multiply the result by 4096.
RSS is "Real Segment Size" and is in 4096 byte segments.

Hi,
I have coulple of Oracle databases running on IBM UNIX server. I could
calculate the total memory used by Oracle processes by running Oracle
scripts. Does anyone know how to get the TOTAL MEMORY USAGE for ORACLE and
NON-ORACLE processes???
Thanks in advance!
