Which three are true about cloning databases into an existing CDB with RMAN? (Choose three.)
Which three are true about cloning databases into an existing CDB with RMAN? (Choose three.)
To clone a database into an existing CDB with RMAN, certain conditions must be met. Firstly, a user with SYSDBA or SYSBKUP must be logged in with RMAN to the non-CDB being cloned, ensuring authorized access during the cloning process. Secondly, the target and auxiliary instance passwords must be the same to maintain consistent authentication across instances. Lastly, when cloning a PDB, it is necessary for a user with SYSDBA or SYSBKUP privileges to be logged in with RMAN to the CDB$ROOT, as this is the root container within the CDB. These criteria ensure the cloning process is secure, controlled, and correctly authenticated.
BEF correct
25.5.3.2 Restrictions on Duplicating a PDB to an Existing CDB Duplicating a PDB to an existing CDB is subject to certain restrictions. Only active database duplication is supported. Only the following clauses of the DUPLICATE command are supported: NORESUME, DB_FILE_NAME_CONVERT, SECTION SIZE, and USING COMPRESSED BACKUPSET. The following clauses of the DUPLICATE command are not supported: SPFILE, NO STANDBY, FARSYNC STANDBY, and LOG_FILE_NAME_CONVERT. Duplicating a PDB to a CDB that is a standby database is not supported. Only one PDB can be duplicated at a time. Partial PDB duplication is not supported, only complete PDB duplication is supported. For example, you cannot include or exclude specific tablespaces while duplicating a PDB. Duplicating a non-CDB as a PDB in an existing CDB is not supported. Duplicating PDBs that contain TDE-encrypted tablespaces is not supported.
Only one PDB can be duplicated at a time. Duplicating and existing pdb into a cdb require sysdba or sysbackup connections. of course password files must be identical
100% BEF as said in documentation: 25.5.3.2 Restrictions on Duplicating a PDB to an Existing CDB (https://docs.oracle.com/en/database/oracle/oracle-database/19/bradv/rman-duplicating-databases.html#GUID-D95D9275-5882-4D5B-846F-1A03304BC307)
BCF Two or more PDBs can be cloned with the same command.
