2.5.3.2 Increasing Swap Space

Use mkfile(1M) and swap(1M) to increase the size of the swap space on a workstation. You must become superuser to do this. mkfile creates a file of a specific size, and swap -a adds the file to the system swap space:

demo# mkfile -v 90m /home/swapfile
/home/swapfile 94317840 bytes
demo# /usr/sbin/swap -a  /home/swapfile
