Recovering All Blocks in V$DATABASE_BLOCK_CORRUPTION
In this scenario, RMAN automatically recovers all blocks listed in the V$DATABASE_BLOCK_CORRUPTION
view.
To recover all blocks logged in V$DATABASE_BLOCK_CORRUPTION:
-
Start SQL*Plus and connect to the target database.
-
Query
V$DATABASE_BLOCK_CORRUPTION
to determine whether corrupt blocks exist. For example, execute the following statement:SQL> SELECT * FROM V$DATABASE_BLOCK_CORRUPTION;
-
Start RMAN and connect to the target database.
-
Recover all blocks marked corrupt in
V$DATABASE_BLOCK_CORRUPTION
.The following command repairs all physically corrupted blocks recorded in the view:
RMAN> RECOVER CORRUPTION LIST;
After the blocks are recovered, the database removes them from
V$DATABASE_BLOCK_CORRUPTION
.
END
