commands to resize swap

Glenn D.Apr 7 2013 — edited Apr 8 2013

Hello,
Questions.
1. How can the swap partition be increased [1] . Using oracle linux 6.4, What commands can do this?
2. The partition next to it will need t be shrunk/moved somehow. What commands can do this?

The reason I am asking this is so Oracle Database software 11gr2 can install , it checks the swap size, and the install wont proceed unless swap is set to a minimum limit.
Thanks Glenn
