difference between SWAP area and /tmp dir
Hello all..
Sun 5.8 and Oracle 9.2/oracle 8.1.7.0
Basic Question....
Is /tmp directory space same as SWAP area ?....because from the command df -k , i see /tmp as 1.18G . Is this same as SWAP area or do we see swap area some where else ?....

thankyou all

/tmp and swap area
in sun system, you can have multiple swap areas defined in multiple locations(ideally diff disks). with your df -k o/p it is very clear that /tmp is swap only.

When i issue the command ....
****************************************************
$ swap -l
swapfile dev swaplo blocks free
/dev/vx/dsk/swapvol 199,7 16 2097120 1841136
******************************************************
so iam a little confused.....in df -k , i see
swap 1154672 24 1154648 1% /var/run
swap 1155200 552 1154648 1% /tmp
So can anyone explain wht swap -l is showing 1.8G free while df -k shows 1.15G Free ?...
Thanks a lot

No, what is clear is that the swap space is in tmp, not that tmp is swap space only.
-
swap -l shows the current devices configured to maintain swap space
swap -s shows the hard disk space allocated AND the memory available for swap space
