If you want to add temporary swap space then you can create a directory which should have the required space and then create the additional swap on that as follows:
#swapinfo -tam
#mkdir //tempswap1
#chmod 777 /
#swapon -p2 -l 1000M /
(-p2 priority 2)
#swapinfo –tam
* 1000M is 1000 MB swap space which will be created
* tempswap1 is just an example, you can give any name you want but it will be good if you can identify that it is a swap space just by looking at the name of the directory
* 777 is the permission setting for the directory created
