The restore of Oracle data can be done from within RMAN and we restore the backup files from NetBackup to a temporary location on the Oracle server.
To log in to RMAN, type the command below into a Command Line window.
|
rman target / |
As soon as you log in to the database, the DBID currently in use will be displayed.

Recovery Manager: Release 11.2.0.1.0 - Production on Fri Nov 9 11:53:46 2018 Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved. connected to target database: ORCL (DBID=1490584423) RMAN> |
Step 1
From Netbackup restore the Oracle backup as files, and then copy them to a temporary location on the Oracle server.
In our example, we have copied them to the location of "C:\Backup\Oracle".
Step 2
|
RMAN> STARTUP NOMOUNT; |
Step 3
Restore the control file.
|
RMAN> RESTORE CONTROLFILE FROM "C:\Backup\Oracle\ctrl_ORCL_2924.dbf"; |
Restore of control file changes the DBID to the target DBID. Run a select DBID from v$database; from SQL to verify that.
Step 4
Mount the database.
|
RMAN> ALTER DATABASE MOUNT; |
Step 5
Configure sbt device.
|
RMAN> CONFIGURE DEVICE TYPE sbt_tape PARALLELISM 1; RMAN> CONFIGURE CHANNEL DEVICE TYPE sbt_tape PARMS='SBT_LIBRARY=oracle.disksbt,ENV=(BACKUP_DIR=C:\Backup\Oracle)'; |
Step 6
Catalog each of the dbf files in turn.
|
RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_10%3A962806106%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_11%3A977481621%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_12%3A977481656%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_16%3A977491557%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_17%3A977491557%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_18%3A977491557%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_19%3A977491557%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_2%3A962805087%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_20%3A977491575%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_21%3A977491602%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_22%3A977491602%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_23%3A977492038%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_24%3A977492038%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_25%3A977492038%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_26%3A977492046%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_27%3A977492058%3A1%3E.dbf'; RMAN> catalog device type 'SBT_TAPE' backuppiece 'B_ORA_All_Full_BS068%3CORCL_9%3A962806071%3A1%3E.dbf'; |
