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.

connected to target database: ORCL (DBID=1490584423)

RMAN>


Step 2

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 3

RMAN> STARTUP NOMOUNT;

Step 4

Restore the control file.

RMAN> REPLICATE 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 5

Mount the database.

RMAN> ALTER DATABASE MOUNT;

Step 6

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 7

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';

Step 8
