18c Database : Duplicate PDB with RMAN

In 18c, we can use RMAN command DUPLICATE to copy the PDB into an existing CDB. In previous releases we need to clone that to a new CDB and unplug and plug into a current CDB.

Only active database based duplication is allowed and only one PDB is supported. Log file name convert and spfile parameters also not supported.

Connect AS TARGET to the root of the source CDB as a common user with the SYSDBA or SYSBACKUP privilege.

Connect AS AUXILIARY to the root of the destination CDB as a common user with the SYSDBA or SYSBACKUP privilege.

DUPLICATE PLUGGABLE DATABASE pdb1dup TO cdb1
DB_FILE_NAME_CONVERT('cdb1','pdb1')
FROM ACTIVE DATABASE
SECTION SIZE 400M;

-Thanks

Suresh
