RE: multiple databases in a single RAC cluster

Yes, absolutely, we have one customer who has an 8 node RAC cluster that's 
running 12 databases, each with between 2 and 8 instances, and a pile of other 
customers with 2-4 node clusters with multiple databases.  I'm sure there's 
some internal limitations as to the number of services that can be registered 
in the CRS, but I doubt many people run into it.

Subject: multiple databases in a single RAC cluster
Hi, As much as Ive been browsing / studying rac... Im looking for a 
definitive answers about how many "databases" can be on one rac cluster.

Say I want to have 4 independent databases on one cluster, is that 
possible? I understand one can easily have multiple instances pointing 
to a single database (sga, control_file, db_name, spfile, archive_dest, 
etc) but what about several independent databses?

Any documents referencing this?

I found this on ask tom... just wanted to confirm with this group, 
probably in a more concise manner.

So,  How many databases (sga, control_file, db_name, spfile, 
archive_dest, etc)  can be in a single rac cluster?
