Block Media Recovery
Oracle introduced the ability to perform block level recovery in 9i. The following syntax can be used to perform block level recovery:

RMAN> blockrecover datafile 1 block 2;

OR

run {
allocate channel c1 device type disk|sbt;
blockrecover datafile 1 block 2;
}

Note these restrictions of block media recovery:

• You can only perform block media recovery with RMAN. No SQL*Plus recovery interface is available.
• You can only perform complete recovery of individual blocks. In other words, you cannot stop recovery before all redo has been applied to the block.
• You can only recover blocks marked media corrupt. The V$DATABASE_BLOCK_CORRUPTION view indicates which blocks in a file were marked corrupt since the most recent BACKUP or BACKUP ... VALIDATE command was run against the file.
• You must have a full RMAN backup. Incremental backups are not allowed. Note that Block media recovery is able to restore blocks from parent incarnation backups and recover the corrupted blocks through a RESETLOGS.
• Blocks that are marked media corrupt are not accessible to users until recovery is complete. Any attempt to use a block undergoing media recovery results in an error message indicating that the block is media corrupt.
