This view lists information about control files in backup sets. The V$BACKUP_DATAFILE view contains both data file and control file records: a backup data file record with file number 0 represents the backup control file. In the recovery catalog, the RC_BACKUP_CONTROLFILE view contains only control file records, while the RC_BACKUP_DATAFILE view contains only data file records.
| Column | Data Type | Description |
|---|---|---|
DB_KEY |
NUMBER |
The primary key for this database in the recovery catalog. Use this column to join with almost any other catalog view. |
DBINC_KEY |
NUMBER |
The primary key for the incarnation of the target database. Use this column to join with RC_DATABASE_INCARNATION. |
DB_NAME |
VARCHAR2(8) |
The DB_NAME of the database incarnation to which this record belongs. |
BCF_KEY |
NUMBER |
The primary key of the control file backup in the recovery catalog. If you issue the LIST command while RMAN is connected to the recovery catalog, then this value appears in the KEY column of the output. |
RECID |
NUMBER |
The RECID value from V$BACKUP_DATAFILE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file. |
STAMP |
NUMBER |
The STAMP value from V$BACKUP_DATAFILE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file. |
BS_KEY |
NUMBER |
The primary key of the backup set to which this record belongs in the recovery catalog. Use this column to join with RC_BACKUP_SET or RC_BACKUP_PIECE. |
SET_STAMP |
NUMBER |
The SET_STAMP value from V$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. |
RESETLOGS_CHANGE# |
NUMBER |
The SCN of the most recent RESETLOGS when the record was created. |
RESETLOGS_TIME |
DATE |
The time stamp of the most recent RESETLOGS when the record was created. |
CHECKPOINT_CHANGE# |
NUMBER |
The control file checkpoint SCN. |
CHECKPOINT_TIME |
DATE |
The control file checkpoint time. |
CREATION_TIME |
DATE |
The control file creation time. |
BLOCK_SIZE |
NUMBER |
The size of the blocks in bytes. |
OLDEST_OFFLINE_RANGE |
NUMBER |
Internal use only. |
STATUS |
VARCHAR2(1) |
The status of the backup set: A (available), U (unavailable), or D (deleted). |
BS_RECID |
NUMBER |
The control file RECID of the backup set that contains this backup control file. |
BS_STAMP |
NUMBER |
The control file stamp of the backup set that contains this control file. |
BS_LEVEL |
NUMBER |
The incremental level (NULL, 0, 1) of the backup set that contains this backup control file. Although an incremental backup set can contain the control file, it is always contains a complete copy of the control file. There is no such thing as an incremental control file backup. |
COMPLETION_TIME |
DATE |
The date that the control file backup completed. |
CONTROLFILE_TYPE |
VARCHAR2(1) |
The type of control file backup: B (normal backup) or S (standby backup). |
BLOCKS |
NUMBER |
The number of blocks in the file. |
AUTOBACKUP_DATE |
DATE |
The date of the control file autobackup. |
AUTOBACKUP_SEQUENCE |
NUMBER |
The sequence of the control file autobackup: 1 - 255. |
