Kernel use of real memory

daniels · #1 (**permalink**) 12-12-2005

Hello AIX gurues...
In order to present the statistics of real memory usage I need to know how much real memory is used by the AIX 5L kernel. No the exact figures of course but some close to the reality.
The AIX is running in a 7GB real machine, it has a HACMP configuration and my concern is because the paging rate is high very frequently.
According with the applications staff, there are not new applications to justify the paging rate and they say its a bad tuning of the Operating system parms.
Could somebody give me a hint?
Regards
Daniel

the RAM in your machine will have a device file assiciated with it in the /dev directory... usually its /dev/mem0, if u have another RAM its /dev/mem0 and /dev/mem1 etc.....

to find out the real memory, issue the command....

lsattr -El /dev/mem0
(or)
lsattr -El mem0

do this for each RAM device on your system.....
