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.

BDF_KEY

NUMBER

The primary key of the datafile backup in the recovery catalog. If you issue the LIST command while connected to the recovery catalog, this value appears in the KEY column of the output.

RECID

NUMBER

The backup datafile RECID from V$BACKUP_DATAFILE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.

STAMP

NUMBER

The backup datafile stamp from V$BACKUP_DATAFILE. 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.

BS_RECID

NUMBER

The RECID from V$BACKUP_SET.

BS_STAMP

NUMBER

The STAMP from V$BACKUP_SET.

BACKUP_TYPE

VARCHAR2(1)

The type of the backup: D (full or level 0 incremental) or I (incremental level 1).

INCREMENTAL_LEVEL

NUMBER

The level of the incremental backup: NULL, 0 , or 1.

COMPLETION_TIME

DATE

The completion time of the backup.

FILE#

NUMBER

The absolute file number of the datafile. Note that when FILE#=0, the record refers to the control file. See the note following this table for special semantics of other columns when FILE#=0.

CREATION_CHANGE#

NUMBER

The creation SCN of the datafile.

RESETLOGS_CHANGE#

NUMBER

The SCN of the most recent RESETLOGS in the datafile header.

RESETLOGS_TIME

DATE

The time stamp of the most recent RESETLOGS in the datafile header.

INCREMENTAL_CHANGE#

NUMBER

The SCN that determines whether a block will be included in the incremental backup. A block is only included if the SCN in the block header is greater than or equal to INCREMENTAL_CHANGE#.

The range of redo covered by the incremental backup begins with INCREMENTAL_CHANGE# and ends with CHECKPOINT_CHANGE#.

CHECKPOINT_CHANGE#

NUMBER

The checkpoint SCN of this datafile in this backup set.

CHECKPOINT_TIME

DATE

The time associated with CHECKPOINT_CHANGE#.

ABSOLUTE_FUZZY_CHANGE#

NUMBER

The absolute fuzzy SCN. See the note following this table for special semantics when FILE#=0.

DATAFILE_BLOCKS

NUMBER

The number of data blocks in the datafile.

BLOCKS

NUMBER

The number of data blocks written to the backup. This value is often less than DATAFILE_BLOCKS because for full backups, blocks that have never been used are not included in the backup, and for incremental backups, blocks that have not changed are not included in the backup. This value is never greater than DATAFILE_BLOCKS.

BLOCK_SIZE

NUMBER

The size of the data blocks in bytes.

STATUS

VARCHAR2(1)

The status of the backup set: A (all pieces available), D (all pieces deleted), O (some pieces are available but others are not, so the backup set is unusable).

BS_LEVEL

NUMBER

The incremental level (NULL, 0, or 1) specified when this backup was created. This value can be different from the INCREMENTAL_LEVEL column because if you run, for example, a level 1 incremental backup, but no previous level 0 backup exists for some files, a level 0 backup is automatically taken for these files. In this case, BS_LEVEL is 1 and INCREMENTAL_LEVEL is 0.

PIECES

NUMBER

The number of backup pieces in the backup set that contains this backup datafile.
