Creating the partition is the first step, you need to do two other things
to make your swap partition work on boot:

a) setup the swap space with mkswap - see man mkswap for details

b) tell the system you want this to be swap space by adding a line to
/etc/fstab.  eg.:

/dev/sda5               swap                    swap    defaults       0 0

If you don't want to reboot to activate the swap space you can use the
swapon command, "swapon -a" to activate all the swap partitions in
/etc/fstab or "swapon device" to activate the swap on a particular device
- see man swapon for details (priorities can be useful if you have more
than one physical device, or if you're using swap files.)
