Which are two of the steps taken by Database Configuration Assistant (DBCA) to clone a remote pluggable database (PDB) starting from Oracle 19c? (Choose two.)
To clone a remote pluggable database (PDB) starting from Oracle 19c using DBCA, two critical steps are creating a database link from CDB$ROOT in the local database to the PDB in the remote system that is to be cloned, which allows for the necessary remote connection, and opening the cloned PDB. These steps ensure that the database link is correctly established with the specific remote PDB and that the cloned PDB becomes accessible after the cloning operation is complete.
BC The DBCA operation executes the following steps: 1. Checks the presence of the database link. If the database link exists, DBCA drops it. 2. Creates the database link 3. Creates the PDB from the remote PDB 4. Checks the status of the cloned PDB to verify that it is in mounted mode 5. Opens the cloned PDB
BC i think
Choosing B,C. But B,D could be correct too https://oracle-base.com/articles/19c/multitenant-dbca-pdb-remote-clone-19c
I think BC is correct. This 15-minute tutorial shows you how to use Database Configuration Assistant (DBCA) to clone a remote pluggable database (PDB) into a container database (CDB). https://docs.oracle.com/en/database/oracle/oracle-database/19/clone-pdbs-using-dbca-silent-mode/index.html Prepare the PDB Before Cloning Step 5: Create a common user in ORCL, used in the database link automatically created in CDB19 to connect to ORCL during the cloning operation. Note: to connect to ORCL during the cloning operation > automatically created in CDB19
I think BC
BC https://docs.oracle.com/en/database/oracle/oracle-database/19/multi/cloning-a-pdb.html#GUID-32AE49B1-13A7-4A4D-AB43-BA781ECA99D6 https://oracle-base.com/articles/19c/multitenant-dbca-pdb-remote-clone-19c https://docs.oracle.com/en/database/oracle/oracle-database/19/admin/creating-and-configuring-an-oracle-database.html#GUID-6EDDC43D-9BD6-4096-8192-7E548B826360 The database link can connect as a common user to the root of the source CDB, or as a common or local user to the source PDB. The source PDB can be either a standard PDB or application PDB. => so D could be also TRUE, but who knows what DBCA does.
C for sure, maybe not D: see example: https://docs.oracle.com/en/database/oracle/oracle-database/19/multi/relocating-a-pdb.html#GUID-146006B7-42F1-47EB-B1BA-C3F8E6DD89A8
