Duplicating a PDB into Another CDB
In Oracle Database 12c , it is possible to use the DUPLICATE command at the PDB level. However, there is a limitation: a new CDB must also be created as part of the duplication process. Otherwise, the operation fails with an error. [oracle@cdb2 ~]$ rman target sys/sys@cdb1 auxiliary sys/sys@cdb2 connected to target database: cdb1 (DBID=4178530773) connected to auxiliary database: cdb2…
Oracle Database 18c introduced the capability to duplicate a PDB directly into an existing CDB. This process involves transferring archived redo logs from the source CDB to the target CDB to apply any changes that may have occurred in the source PDB during the duplication. To set up this operation, you must specify the location to store the transferred archived redo logs using the REMOTE_RECOVERY_FILE_DEST parameter. Once the parameter is configured, you can use RMAN to perform the PDB duplication.
