Restore pluggable database from RMAN CDB backup in Oracle

Restore Pluggable database with RMAN Advisory

Recover the Pluggable database with RMAN advisory from CDB completed backup in Oracle.

Error:

SQL> alter pluggable database pdb3 open;
alter pluggable database pdb3 open
*
ERROR at line 1:
ORA-01157: cannot identify/lock data file 34 - see DBWR trace file
ORA-01110: data file 34: 'D:\ORACLE\18.0.0\ORADATA\XE\PDB3\UNDOTBS01.DBF'

Solution
We are using RMAN Advisory for recovery the pluggable database from RMAN Backup.

1. Connect with RMAN

C:\Users\oracle>rman target sys
Recovery Manager: Release 18.0.0.0.0 - Production on Tue Mar 12 11:36:55 2019
Version 18.4.0.0.0
Copyright (c) 1982, 2019, Oracle and/or its affiliates. All rights reserved.
target database Password:
connected to target database: XE (DBID=2882898177)

2. Check the failure with RMAN advisory

RMAN> LIST FAILURE;
using target database control file instead of recovery catalog
Database Role: PRIMARY

List of Database Failures
=========================
Failure ID Priority Status Time Detected Summary
———- ——– ——— ————- ——-
1242 CRITICAL OPEN 12-MAR-19 System datafile 32: ‘D:\ORACLE\18.0.0\ORADATA\XE\PDB3\SY
STEM01.DBF’ is missing
528 HIGH OPEN 12-MAR-19 One or more non-system datafiles are missing

3. Run the Advise failure command to get the script
Advice command will help us that we have rman backup to recover this failure.

RMAN> advise failure;

4. If file D:\ORACLE\18.0.0\ORADATA\XE\PDB3\UNDOTBS01.DBF was unintentionally renamed or moved, restore it

Automated Repair Options
========================
Option Repair Description
—— ——————
1 Restore and recover datafile 32; Restore and recover datafile 33; Restore and recover datafile 34
Strategy: The repair includes complete media recovery with no data loss
Repair script: D:\ORACLE\18.0.0\diag\rdbms\xe\xe\hm\reco_3136680222.hm

4. Check the script provided in advice preview command

RMAN> REPAIR FAILURE PREVIEW;

Strategy: The repair includes complete media recovery with no data loss
Repair script: D:\ORACLE\18.0.0\diag\rdbms\xe\xe\hm\reco_3136680222.hm
contents of repair script:
# restore and recover datafile
sql ‘PDB3’ ‘alter database datafile 32, 33, 34 offline’;
restore ( datafile 32, 33, 34 );
recover datafile 32, 33, 34;
sql ‘PDB3’ ‘alter database datafile 32, 33, 34 online’;

5. Finally start the Repairing Script provided by RMAN Advisory
RMAN> REPAIR FAILURE;

Strategy: The repair includes complete media recovery with no data loss
Repair script: D:\ORACLE\18.0.0\diag\rdbms\xe\xe\hm\reco_3136680222.hm

contents of repair script:
# restore and recover datafile
sql ‘PDB3’ ‘alter database datafile 32, 33, 34 offline’;
restore ( datafile 32, 33, 34 );
recover datafile 32, 33, 34;
sql ‘PDB3’ ‘alter database datafile 32, 33, 34 online’;

Do you really want to execute the above repair (enter YES or NO)? YES
executing repair script

6. Open the Pluggable Database

SQL> alter pluggable database pdb3 open;
Pluggable database altered.

Note: It will check recreate the temp file in backgroud. you can check in alert log.
