There are two ways to add swap in Sun Server(i.e. Sun

Solaris) as below;

1. Make a partion at availbale free disk of required swap

size and then make an entry in /etc/vfstab file. After that

run the command #swapadd /dev/dsk/cXtXdXsX or give the

reconfiguration reboot to the Server.

2. Instead of making partion you can create make a file of

required swap size with the help of #mkfile <size>

<filename> command and after that make an entry

in /etc/vfstab and follow rest of steps mention in point

one.
