How to check RMAN errors?
One way to determine whether RMAN encountered an error is to examine its return code, as described in “Identifying RMAN Return Codes”.

How does RMAN detect block corruption?
You can check for logical corruption in the database by running the BACKUP (with or without VALIDATE option) with the CHECK LOGICAL command. If RMAN finds corrupt blocks, then it populates V$DATABASE_BLOCK_CORRUPTION . The backup will stop if the number of corrupt blocks exceeds MAXCORRUPT .
How do I know if my RMAN backup was successful?
