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 Database has discovered this corrupt block and marked it in the database as corrupt. When a corrupt block is encountered in a backup, and is not marked corrupt by Oracle Database, 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.
