How to calculate non-file backed memory under RHEL? I mean it was like Computational memory under AIX. Do we have any indicator like "virtual" in svmon under AIX？
Does it compute like:

It sounds like you're looking for the
free command. The output will look something like this:
total used free shared buffers cached Mem: 7134716 1002972 6131744 436 82652 578308 -/+ buffers/cache: 342012 6792704 Swap: 0 0 0
This shows you the breakdown of your memory in bytes. There are flags to switch to kibibytes, mebibytes, etc, if you prefer.
Swap is file backed memory.
Mem is the equivalent of AIX's computational memory.
