Validate Oracle Backup from Tape

Purpose:

The main purpose of RMAN validation is to check for corrupt blocks and missing files. You can also use RMAN to determine whether backups can be restored. You can use the following RMAN commands to perform validation:

Configure Flashback Database

Configuring Flashback Database

The steps for configuring Flashback database option in  are:

Configure database to run in ARCHIVELOG mode.

Ensure the datbase is operating in ARCHIVELOG mode.


SQL> ARCHIVE LOG LIST

Database log mode            Archive Mode
Automatic archival              Enabled
Archive destination             /home/oracle/archiev1
Oldest online log sequence          5
Next log sequence to archive      7
Current log sequence                 7


If not, shutdown immediate, then startup mount, and alter the database

SQL> alter database archivelog;


Configure Flashbask when the instance in mount operating mode

SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP MOUNT
SQL> ALTER DATABASE FLASHBACK ON;

Database altered.


Configuring flashback database related parameters

SQL> ALTER SYSTEM SET DB_RECOVERY_FILE_DEST =
          '/home/oracle/flash_recover_area' scope=both;


SQL> ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE = 3G SCOPE=both;


SQL> ALTER SYSTEM SET DB_FLASHBACK_RENTENTION_TARGET = 4320 SCOPE=both;


SQL> show parameter DB_FLASH

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_flashback_retention_target        integer     4320


SQL> show parameter db_recovery_file

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      /home/oracle/flash_recovery_area

db_recovery_file_dest_size           big integer 3G


Obtain SCN before initiating a database change.

SQL> select current_scn from v$database;

CURRENT_SCN
-----------
     945046


Perform database change

SQL> drop table scott.salgrade;

Table dropped.


Performing  flashback database

SQL> shutdown immediate;

Database closed.
Database dismounted.
ORACLE instance shut down.


SQL> startup mount;

ORACLE instance started.

Variable Size             163578280 bytes
Database Buffers          436207616 bytes
Redo Buffers                7106560 bytes
Database mounted.



SQL> FLASHBACK DATABASE TO SCN 945046;

Flashback complete.

Open the Database with RESETLOGS.


SQL> alter database open resetlogs;
