Dear
How i can know the ( RAM and CPU ) on unix. we use AIX operating system.
This is for security purposes.
Try prtconf
That would be easiest, or if you're more masochistic, just do an "lsattr -El sys0", or "lscfg -vp"...heh.
I think you will find the lscfg -vp will show all the memory in the system, not just the LPAR, so beware!
on AIX 5L you can use lparstat -i, even if it's a standalone system
not sure if it works on AIX 5.1 and 5.2
i prefer lsconf
All the above commands are useful. Let me add a few more,
Memory (RAM) on the system : bootinfo -r
CPU on the system : lsdev -Ccprocessor
Regds, Kaps
With a space between the -Cc and processor:
lsdev -Cc processor
It works w/o a space too ;;)--
Try it, It works.
Well that's two things I've learnt today, that and how to use smilies, I'll be off home now then 
The best thing about unix is that [ am not talking abt the smiley] , you get to learn something new everyday.
