Goal

How to rename a datafile in the primary database and manually propagate the changes to the standby database.

When you rename one or more datafiles in the primary database, the change is not propagated to the standby database, even if the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO.

If you do not rename the corresponding datafile at the standby system, and then try to refresh the standby database control file, the standby database will attempt to use the renamed datafile, but it will not find it. Consequently, you will see error messages similar to the following in the alert log:

ORA-00283: recovery session canceled due to errors
ORA-01157: cannot identify/lock datafile 14 - see DBWR trace file
ORA-01110: datafile 14: '/Disk1/oracle/oradata/mum/payroll_01.dbf'

Solution

The following steps describe how to rename a datafile in the primary database and manually propagate the changes to the standby database.

1. Set STANDBY_FILE_MANAGEMENT=MANUAL on both Primary and Standby Database.

SQL>ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=MANUAL;

2. Take the Tablespace offline on the Primary Database:

SQL> ALTER TABLESPACE tbs_4 OFFLINE;

3. Rename Datafile on Primary Site:

% mv /Disk1/oracle/oradata/mum/payroll_1.dbf /Disk1/oracle/oradata/mum/payroll_01.dbf

4. Rename the Datafile in the Primary Database and bring the Tablespace back online:

SQL> ALTER TABLESPACE tbs_4 RENAME DATAFILE '/Disk1/oracle/oradata/mum/payroll_1.dbf' TO '/Disk1/oracle/oradata/mum/payroll_01.dbf';
SQL> ALTER TABLESPACE tbs_4 ONLINE;

5. Stop Redo Apply on Standby Database:

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

6. Shutdown the Standby Database:

SQL> SHUTDOWN;

7. Rename the Datafile at the Standby site :

% mv /Disk1/oracle/oradata/mum/payroll_1.dbf /Disk1/oracle/oradata/mum/payroll_01.dbf

8. Start and mount the Standby Database:

SQL> STARTUP MOUNT;

9. Rename the Datafile in the Standby Database control file.

SQL> ALTER DATABASE RENAME FILE '/Disk1/oracle/oradata/mum/payroll_1.dbf' TO '/Disk1/oracle/oradata/mum/payroll_01.dbf';

Note : STANDBY_FILE_MANAGEMENT initialization parameter must be set to MANUAL.

10. On the Standby Database, restart Redo Apply:

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

11. Set STANDBY_FILE_MANAGEMENT=AUTO on both Primary and Standby Database.

SQL>ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;
