Well, that's a little different question. You use RAC services to configure that. There is pretty extensive documentation on it. The basic theory is that you set by time when each service is available on each instance, and if one server goes down you allow those services currently running on it to fail over to the next.

OK, I had heard that perhaps there are issues because of the interconnect uses UDP. The goal would is to for example allow say 3 databases access to machines A & B during the day, while another database has exclusive access to C & D, then at night allow one of the first three databases to access A, B, C & D.

None that are different than any other requirements. You don't even have to cluster all the instances.

Are there any technical limitations in regards to running multiple databases across the same set of servers in the same cluster
