What do you call swap memory?
What does swapinfo -tam give you?
If you have a swapdevice (such as /dev/vg00/lvol2 ) of 10GB then all depends what you what is tuned in the kernel
If you want to add more device swap then you will have to configure that using sam ->lvm etc...
and most certainly configure a new kernel for you may be asked to increase the value of maxswapchunks... (something like 20000 )
If swapmem_on is set to 1 then it depends how much memory you want to be used by applications...
