AIX: 6.1 64 bits

How to find out Free memory available on AIX 6.1 64 bits

When I used :

svmon -G
               size       inuse        free         pin     virtual   mmode
memory      1048576      612109      191151      215969      549824   Ded-E
pg space    4325376        3288

               work        pers        clnt       other
pin          193849           0           0       22120
in use       541616           0       70493

What is the significance of memory(size) in the 1st Column, inuse and free?
Are they measured in KB?

Thanks for your time!

If you search for "svmon" in this forum you'll find several tons of links. In about half of them the meaning of these values is explained.

So, there, for the umpteenth time:

"inuse" is what you have, minus what is unused ("free"). It is computational and cache memory added together. All these values are in units of memory pages, which is 4K in the overwhelming majority of cases.

Subtract "virtual" (=computational memory, that is: memory used by programs) from "inuse" to get the size of the cache. As a rule of thumb, as long as "virtual" is smaller than "inuse" times 0.9 (in other words progams use less than 90% of the memory) everything is OK, if it is higher you probably see paging activity in "vmstat".

I hope this helps.
