RC_BACKUP_CORRUPTION

This view lists corrupt block ranges in datafile backups. It corresponds to the V$BACKUP_CORRUPTION view in the control file. Note that corruptions are not tolerated in control file and archived redo log backups.

Column	Datatype	Description
`DB_KEY`	`NUMBER`	The primary key for the target database. Use this column to form a join with almost any other catalog view.
`DBINC_KEY`	`NUMBER`	The primary key for the incarnation of the target database. Use this column to form a 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 form a join with `RC_BACKUP_SET`.
`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 datafile backup or copy in the recovery catalog. Use this key to join with `RC_BACKUP_DATAFILE`. If you issue the `list` command while connected to the recovery catalog, 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 datafile that contains the corrupt blocks.
`CREATION_CHANGE#`	`NUMBER`	The creation SCN of the datafile 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 had already discovered this corrupt block and marked it as corrupt in the database. Note that when a corrupt block is encountered in a backup, and was not already marked corrupt by Oracle, then the backup process does not mark the block as corrupt in the production datafile. Thus, this field may be `YES` for the same block in more than one backup set.
`CORRUPTION_TYPE`	`VARCHAR2(9)`	Same as `RC_DATABASE_BLOCK_CORRUPTION.CORRUPTION_TYPE`.
