Upgrading a cluster's OS

edited Jan 13, 2014 8:34AM in Database - RAC/Scalability (MOSC) 3 commentsAnswered
We have an Oracle 11gR2 RAC cluster with 4 nodes. 2 nodes are dedicated to one database that's devoted one application and 2 nodes are dedicated to a completely separate database that serves a completely different application. They got all put on the same cluster. Why? Nobody really knows anymore.

We're looking at changing hardware and OS's and such on two of the nodes for one of the applications. Since they're in the same cluster, we're concerned about how to do this without effecting the other two nodes (or if it can even be done). We're installing two much newer nodes on this database with much newer OSs and I'm not sure if it will even let us add it to the cluster with the newer OS.

Howdy, Stranger!
