RC_BACKUP_CORRUPTION

This view lists corrupt block ranges in data file backups, which may be detected when BACKUP VALIDATE is used or the MAXCORRUPT parameter is greater than 0. It corresponds to the V$BACKUP_CORRUPTION view in the control file. Corruptions are not tolerated in control file and archived redo log backups.

Column	Data Type	Description
`DB_KEY`	`NUMBER`	The primary key for this database in the recovery catalog. Use this column to join with almost any other catalog view.
`DBINC_KEY`	`NUMBER`	The primary key for the incarnation of the target database. Use this column to join with `RC_DATABASE_INCARNATION`.
`DB_NAME`	`VARCHAR2(8)`	The `DB_NAME` of the database incarnation to which this record belongs.
`RECID`	`NUMBER`	The record identifier from `V$BACKUP_CORRUPTION`. `RECID` and `STAMP` form a concatenated primary key that uniquely identifies this record in the target database control file.
`STAMP`	`NUMBER`	The stamp propagated from `V$BACKUP_CORRUPTION`. `RECID` and `STAMP` form a concatenated primary key that uniquely identifies this record in the target database control file.
`BS_KEY`	`NUMBER`	The primary key of the backup set to which this record belongs in the recovery catalog. Use this column to join with `RC_BACKUP_SET` or `RC_BACKUP_PIECE`.
`SET_STAMP`	`NUMBER`	The `SET_STAMP` value from `V$BACKUP_SET`. `SET_STAMP` and `SET_COUNT` form a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file.
`SET_COUNT`	`NUMBER`	The `SET_COUNT` value from `V$BACKUP_SET`. `SET_STAMP` and `SET_COUNT` form a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file.
`PIECE#`	`NUMBER`	The backup piece that contains this corrupt block.
`BDF_KEY`	`NUMBER`	The primary key for the data file backup or copy in the recovery catalog. Use this key to join with `RC_BACKUP_DATAFILE`. If you issue the `LIST` command while RMAN is connected to the recovery catalog, then this value appears in the `KEY` column of the output.
`BDF_RECID`	`NUMBER`	The `RECID` value from `V$BACKUP_DATAFILE`.
`BDF_STAMP`	`NUMBER`	The `STAMP` value from `V$BACKUP_DATAFILE`.
`FILE#`	`NUMBER`	The absolute file number for the data file that contains the corrupt blocks.
`CREATION_CHANGE#`	`NUMBER`	The creation SCN of the data file containing the corrupt blocks.
`BLOCK#`	`NUMBER`	The block number of the first corrupted block in this range of corrupted blocks.
`BLOCKS`	`NUMBER`	The number of corrupted blocks found beginning with `BLOCK#`.
`CORRUPTION_CHANGE#`	`NUMBER`	For media corrupt blocks, this value is zero. For logically corrupt blocks, this value is the lowest SCN in the blocks in this corrupt range.
`MARKED_CORRUPT`	`VARCHAR2(3)`	`YES` if this corruption was not previously detected by Oracle, or `NO` if Oracle has already discovered this corrupt block and marked it as corrupt in the database. If a corrupt block is encountered in a backup that was not marked corrupt by Oracle, then the backup process does not mark the block as corrupt in the production data file. Thus, this field may be `YES` for the same block in multiple backup sets.
`CORRUPTION_TYPE`	`VARCHAR2(9)`	Same as `RC_DATABASE_BLOCK_CORRUPTION.CORRUPTION_TYPE`.
