Oracle Database rename a PDB in a Data Guard configuration?

On the primary I have:

----- PRIMARY

SQL> show pdbs;

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 TEST1                            READ WRITE NO
         4 PROD2                           READ WRITE NO

----- PRIMARY

SQL> show pdbs;
 
    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 TEST1                            READ WRITE NO
         4 PROD2                           READ WRITE NO

And of course the same PDBs on the standby:

----- STANDBY

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       MOUNTED
         3 TEST1                            MOUNTED
         4 PROD2                           MOUNTED

----- STANDBY

SQL> show pdbs
 
    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       MOUNTED
         3 TEST1                            MOUNTED
         4 PROD2                           MOUNTED

Let’s change the PDB test1 name to prod1: The PDB rename operation is straightforward (but it requires a brief downtime). To be done on the primary:

SQL> alter pluggable database test1 close;

Pluggable database altered.

SQL> alter pluggable database red open restricted;

Pluggable database altered.

SQL> alter session set container=test1;

Session altered.

SQL> alter pluggable database rename global_name to prod1;

Pluggable database altered.

SQL> alter session set container=cdb$root;

Session altered.

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PROD1                           READ WRITE YES
         4 PROD2                           READ WRITE NO

SQL> alter pluggable database prod1 close;

Pluggable database altered.


SQL> alter pluggable database prod1 open;

Pluggable database altered.


SQL> alter pluggable database test1 close;
 
Pluggable database altered.
 
SQL> alter pluggable database test1 open restricted;
 
Pluggable database altered.
 
SQL> alter session set container=test1;
 
Session altered.
 
SQL> alter pluggable database rename global_name to prod1;
 
Pluggable database altered.
 
SQL> alter session set container=cdb$root;
 
Session altered.
 
SQL> show pdbs
 
    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PROD1                           READ WRITE YES
         4 PROD2                           READ WRITE NO
 
SQL> alter pluggable database prod1 close;
 
Pluggable database altered.
 
 
SQL> alter pluggable database prod1 open;
 
Pluggable database altered.

On the standby, I can see that the PDB changed its name:

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       MOUNTED
         3 PROD1                           MOUNTED
         4 PROD2                           MOUNTED
SQL> show pdbs
 
    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       MOUNTED
         3 PROD1                           MOUNTED
         4 PROD2                           MOUNTED

The PDB name change is propagated transparently with the redo apply.
