Multitenant Dataguard: Create multitenant database on priamry and standby database using FILE_NAME_CONVERT parameter

Recently we faced some issue on multitenant standby database . As we create pdb on primary same not reflected on standby database as it was conflicting  with destination directory and datafile as well. 

This scenario  about using FILE_NAME_CONVERT parameter we create multitenant  primary pluggable  database and same will reflect on standby database. 

PRIMARY Pluggable database :


SQL> sho pdbs

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


  • NOTE : Create directory in pluggable standby database before creting pluggable database on primary database.

Example: 

[oracle@srv7 ~]$ mkdir -pv /u02/app/oracle/oradata/PRIMARY19C/pdb3

mkdir: created directory ‘/u02/app/oracle/oradata/PRIMARY19C/pdb3’

  • Create Pluggable database on primary database and mention file_name_convert parameter  below and provide directory of new pdb3 we have mentioned  /u02/app/oracle/oradata/PRIMARY19C/pdb3 and it will be created automatically. 

SQL> CREATE PLUGGABLE DATABASE pdb3 ADMIN USER pdb_adm IDENTIFIED BY Password1 FILE_NAME_CONVERT=('/u02/app/oracle/oradata/PRIMARY19C/pdbseed','/u02/app/oracle/oradata/PRIMARY19C/pdb3');


Pluggable database created.

         3 PDB                            READ WRITE NO

Dataguard : Setting protection mode from MAXIMUM PERFORMANCE to MAXIMUM AVAILABILITY

Data guard : Setting protection mode from MAXIMUM PERFORMANCE to MAXIMUM AVAILABILITY

Whenever we change the protection mode in primary database  it will automatically changed in standby database.

Before changing set  ASYNC to SYNC on log_archive_dest_2state. We set  protection mode  in mount state on primary database.

  • Connect primary database  check the current status
