Is it possible to split a RAC cluster in two or more RAC clusters?

in Enterprise Manager Generic (MOSC) 2 commentsAnswered

Say we have a 4-node Oracle RAC Cluster.

Database 1 is running on nodes 1 and 2, while database 2 is running on nodes 3 and 4.

Is it possible to split the 4-node cluster in two 2-node clusters? So that we have a cluster with nodes 1 and 2 with database 1 executing on them and another cluster with nodes 3 and 4 with database 2 executing on them.

Note: as per Oracle documentation it is possible to add and delete nodes to a RAC cluster, but there is no mention to the split option which could be useful in certain circumstances.

Best regards

Nicolau
