Oracle 11g on VM Linux 5.5 (Red Hat 8) extending swap size

[Block16]

I am trying to install Oracle 11g on a Linux VM, my actual machine is windows 7 64bit. I need to increase swap file size as it doesn't meet minimum requirement; I need to increase it by 1GB.
When I use swapon, swapoff, or mount, I get the following message:
bash: swapoff: command not found.
bash: swapon: command not found.
bash: mount: command not found.
I have downloaded the VMware Tools. It should've had all the packages within it--right, but I checked that mount package is not installed and I don't know how to do that.
I will appreciate any insight into this matter.
Thanks.

Try /sbin/swapon or /sbin/swapoff !! and hopefully you're executing the commands as root user.

thanks nu04330. It worked-- and I had been running all the commands as root.
