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	NULL	Description
DB_KEY	NUMBER	NOT NULL	The primary key for the target database. Use this column to form a join with almost any other catalog view.
DBINC_KEY	NUMBER	NOT NULL	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)	NOT NULL	The DB_NAME of the database incarnation to which this record belongs.
RECID	NUMBER	NOT NULL	The record identifier from V$BACKUP_CORRUPTION. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
STAMP	NUMBER	NOT NULL	The stamp propagated from V$BACKUP_CORRUPTION. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
BS_KEY	NUMBER	NOT NULL	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	NOT NULL	The SET_STAMP value from V$BACKUP_SET. SET_STAMP and SET_COUNT form a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file.
SET_COUNT	NUMBER	NOT NULL	The SET_COUNT value from V$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	NOT NULL	The backup piece to which the block belongs.
BDF_KEY	NUMBER	NOT NULL	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	NOT NULL	The RECID value from V$BACKUP_DATAFILE.
BDF_STAMP	NUMBER	NOT NULL	The STAMP value from V$BACKUP_DATAFILE.
FILE#	NUMBER	NOT NULL	The absolute file number for the datafile.
CREATION_CHANGE#	NUMBER	NOT NULL	The SCN at backup creation.
BLOCK#	NUMBER	NOT NULL	The block number of the first corrupted block in the file.
BLOCKS	NUMBER	NOT NULL	The number of corrupted blocks found beginning with BLOCK#.
CORRUPTION_CHANGE#	NUMBER		The SCN at which corruption was detected.
MARKED_CORRUPT	VARCHAR2(3)		YES if this corruption was not previously detected by Oracle or NO if it was already known by Oracle.
