RC_BACKUP_CORRUPTION

This view lists corrupt block ranges in datafile 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. Note that corruptions are not tolerated in control file and archived redo log backups.

Column Datatype 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 datafile 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 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.
