Thanks for your reply dude,In my operations swap memory is used for processes to run..Moreover we dont have any RAM on our node..Swap memory is used instead of Node..The o/p given above is of a voucher server (IN system).
As per our ZLD,if
command provides o/p of availabe space=used space,everything if fine...what does this mean?..

Your total virtual memory size is around 10 GB, half of which been free. You have at least 6 GB of RAM but possibly much more.
The various file systems backed by swap are using a negligible part of virtual memory.
There is no straight relationship between how much swap is used and a system performance. If you want the latter, just make sure you have enough RAM to avoid pagination. If you want your applications not to crash, have enough swap for all memory allocation and reservations to easily fit. Memory allocations do like RAM, memory reservations are fine with on disk swap.

In the df output context, swap is a file system (a.k.a tmpfs) holding files about which sensible numbers are reported. However, you are correct df isn't the right command to investigate memory usage.
Hy all,
i've a little problem with the size of the swap. I've an old solaris machine, with 4Go, and swap is taking 500Mo for only 1% used at any time.
So : how can i change this size without problems ?????

Hi,
the /tmp size is less whereas the size allocated to swap is quite big. how to increase the size of /tmp -

Hi all,
I'm trying to get an understanding of swap. This is what I see:
Memory: 8192M real, 1697M free, 5693M swap in use, 10G swap free
My question(s): If I have available RAM, why am I using swap? Or am I reading this wrong (been known to happen).
Thanks much,
