Creating Pluggable Databases (PDBs) and Cloning Pluggable Database (PDBs) in RAC environment
This technique copies a source PDB from a CDB and plugs the copy into the same CDB or into another CDB. Oracle multitenant option and Oracle 12c RAC will enable scope for Consolidation, Scalable and Reliable environments.
The cloning pluggable databases (PDB) technique is suitable for situations where:
1. If you want to test the application patch of your production RAC pluggable database. You first clone your production application in a cloned PDB, patch the cloned PDB and test.
2. If you wish to diagnose performance issues or perform performance regression tests on your application. Because this operation cannot be done in parallel of the production in the same database, you clone the PDB into another CDB.
