  • Oracle 12C -- clone a remote pdb

    Connect to the remote CDB and prepare the remote PDB for cloning.

    SQL> select con_id,dbid,name,open_mode from v$pdbs;
    
        CON_ID       DBID NAME                           OPEN_MODE
    ---------- ---------- ------------------------------ ----------
             2 1258043702 PDB$SEED                       READ ONLY
             3 3749525766 PDB1                           READ ONLY
             4 2192587015 P4                             MOUNTED
             5  255759235 PDB_TEST                       READ WRITE

    Create a user in the remote database for use with the database link. In this case, we will use a local user in the remote PDB.

    SQL> alter session set container=p4;
    SQL> alter pluggable database p4 open;
    SQL> create user remote_clone_user identified by remote_clone_user ;
    SQL> grant create session,create pluggable database to remote_clone_user;

    Open the remote PDB in read-only mode.

    SQL> alter pluggable database p4 close;
    SQL> alter pluggable database p4 open read only;

    Connect to the local database to initiate the clone.

    SQL> select con_id,dbid,name,open_mode from v$pdbs;
    
        CON_ID       DBID NAME                           OPEN_MODE
    ---------- ---------- ------------------------------ ----------
             2 3671494824 PDB$SEED                       READ ONLY

    Create a database link in the local database, pointing to the remote database.

    SQL> create database link clone_link connect to remote_clone_user identified by remote_clone_user using 'p4';

    Create a new PDB in the local database by cloning the remote PDB.

    SQL> create pluggable database p4 from p4@clone_link create_file_dest='/u12/app/oracle/oradata/p4';

    The PDB is opened in read-write mode to complete the process.

    SQL>  select con_id,dbid,name,open_mode from v$pdbs;
    
        CON_ID       DBID NAME                           OPEN_MODE
    ---------- ---------- ------------------------------ ----------
             2 3671494824 PDB$SEED                       READ ONLY
             3 2880590083 P4                             MOUNTED
    
    SQL> alter pluggable database p4 open;
    SQL> select con_id,dbid,name,open_mode from v$pdbs;
    
        CON_ID       DBID NAME                           OPEN_MODE
    ---------- ---------- ------------------------------ ----------
             2 3671494824 PDB$SEED                       READ ONLY
             3 2880590083 P4                             READ WRITE
