Advantages of having multiple CDBs in the same server/cluster

JOE_humbleOct 31 2017 — edited Oct 31 2017

DB version: 12.2

GI version: 12.2

OS : RHEL 7.4

In the internet , I have come across articles which mentions multiple CDBs in the same server.

Currently, I have a 2 node RAC cluster with three 11.2.0.4 RAC DBs running in it. Using RMAN, I want to migrate these 3 DBs to a 12.2 cluster and convert (consolidate) these DBs to PDBs . All these DBs are of the same version.

Question1. Having multiple CDBs in the same server/cluster is not helpful in the above case. Right ?

Question2. In what circumstance do we need to create multiple CDBs in the same server/cluster ?
