About 3 years ago I wrote a Perl script to try an calculate how much
memory was being used by oracle processes on a linux server.
That brief education was enough to teach me that linux memory
accounting appears to have been written by the likes of accountants
from Enron.
Attached is a script that works on RH 4. I don't think I've tried it on RH
5.
At the time I thought it about 85-90% accurate, which was enough for my
purposes.
Give it a try if you like.
Please let me know if you think it has glaring errors.
