RE: 10gR2 RAC

The reason that we are going to create second RAC on the same server where already had a 2-node RAC running is we would like to separate our development instance for each production databases, but don't think this is a good idea of buying another 2 new servers for it. Hope this clear your Qs.

I'm a bit unclear on what you're trying to do here. If I'm reading it correctly, you have an existing cluster running 10gR2 RAC with ASM (are they in different ORACLE_HOME's, by the way?) and you want to create another RAC database. Is that correct?

If it is, I guess my question back to you is why? Why not run these together in a single database? Doing that would minimize resource usage and administration time. I'm not sure what benefit you get from having two databases, unless you have some application that has to be in its own database to be supported by the vendor (and even there I'd go back to the vendor and ask them to explain why).
