A single node RAC install means that CRS is installed, and db and other services run under the control of CRS, and you have the option of adding another node at a later date without having to reinstall the software (i.e. converting from a non-RAC to a RAC install). Sometimes we get requests to create a single node RAC for testing- it is more to simplify the DBA's work during a later conversion to RAC, or to validate the OS platform for RAC without having to get a 2nd node.

I really don't like getting into licensing questions ... however  

What is a single-node RAC installation?  

I believe all Enterprise Edition gets you is the ability to use the Clusterware (Grid Infrastructure), not install the RAC option in the database.

Jon -  

You probably have to verify with your customer support rep, but I believe even a single-node RAC installation requires a the RAC license.  

All licensing questions usually favor Oracle.

If I run a single-node RAC cluster, do I actually need to purchase a RAC license, or will a Oracle Enterprise license be sufficient ?
