Provide a simple process for either migration of a single PDB or execution of a single PDB failover into another container database with minimal downtime to the impacted PDB and zero impact to any remaining primary PDBs in the primary CDB. The process takes advantage of new functionality added to the Data Guard broker command line interface DGMGRL.
The steps involve changes being made to 2 independent CDBs, caution must be taken to understand, validate and execute the steps documented below.
The functionality is supported in 220.127.116.11 and later Oracle RDBMS versions. Support for managing Transparent Data Encryption (TDE) keys is available for Oracle RDBMS 19.15 and later versions through a patch.
