Hi Everybody....

I have a confusion about the "top" command output given below, can anyone explain these different numbers:

#top
Memory: 197804K (104700K) real, 303980K (175456K) virtual, 341364K free

Thanks in adv..

Shalom,

real memory is physical memory on the system.

Virtual memory is swap, disk based memory.

The figures in brackets are mount free.

You might find swapinfo -tam less confusing.

HP-UX defines overall system memory as physical memory plus swap.

R.K,

In TOP memory area things are listed in order as given below:

total pshysical memory
active physical memory
virtual memory
free vitual memory
total free memory

For more info refer to :

#swapinfo -tam is even better to see all details.

To know your physical memory, you can check with

dmesg | grep physical
glance ( option m)
swapinfo -tam
SAM

Thanks
