I'm no Linux expert, so I'll leave that bit to Howard. :)

If the OS is capable of adding another node without downtime, then yes it's as simple as adding another instance in Oracle terms. WHen you do this, you'll need to add an extra thread of redo for the new instance, and possibly an extra undo tablespace. Depending on how your clients connect, you may also need to modify the tnsnames file for them.

HTH. Additions and corrections welcome.
