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:

1. Start SQL*Plus and connect to the target database.

2. Query V$DATABASE_BLOCK_CORRUPTION to determine whether corrupt blocks exist. For example, execute the following statement:

   SQL> SELECT * FROM V$DATABASE_BLOCK_CORRUPTION;
   

3. Start RMAN and connect to the target database.

4. 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
