Currently my work env as 1 node none RAC database 11gR2, we are getting another machine (Linux), so I need to add on this node to our currently env and becoming a RAC db. What is the best way/route to do it? Advanced thanks!

In the documentation, there are numerous resources available online explaining how to propote a non-RAC DB to a single node Cluster (and then adding another node to the cluster). – Ohadi May 16 '12 at 14:00

See the Oracle Real Application Clusters Installation Guide 11g Release 2 for Linux and UNIX. It has a section on "Converting to Oracle RAC from Single-Instance Oracle Databases" describing several different ways this can be done.
