1. Login as a root, check the swap space devices and resources.
# swap -l swapfile dev swaplo blocks free /dev/dsk/cxdxtxsx xx,x x xxxxxxx xxxxxxx
# swap -s total: xxxxxk bytes allocated + xxxxxk reserved = xxxxxk used, xxxxxk available
2. Use mkfile to create a swap file. For example, create 512MB size of swap space.
# mkfile 512m /usr/local/swap
3. Add the file created in the swap area.
# swap -a /usr/local/swap
4. Check the swap space again.
# swap -l swapfile dev swaplo blocks free /dev/dsk/cxdxdxsx xx,x x xxxxxxx xxxxxxx /usr/local/swap - x xxxxxxx xxxxxxx
5. Above step is not a permanent add to the system. If a reboot occurred, the swap space will be remove automatically. To add the swap space permanently, you need to add the below lines into the /etc/vfstab.
/usr/local/swap - - swap - no -
