There are many factors to consider, on one hand, you can set application affinity and help the load balancer through that, though running a 9 node database may not be the best. I'd go with 3 clusters (3 nodes each) and have the clusters as DRS for each other, having Higher availability and avoiding extra overhead due to cache fusion and separating databases, specially if they have different production times, SLA, etc.

Subject: RAC newbie question
I am curious on your thoughts on this.......we have 3 unrelated databases and 9 boxes to put them on.
Would you recommend one 9 node cluster and put them on that one or three 3 node clusters (one for each database)?
We are looking at the pros/cons of each. Does anyone have any thought either way?
