Recovery Catalog Views, 3 of 28

RC_BACKUP_CONTROLFILE

This view lists information about control files in backup sets. Note that the V$BACKUP_DATAFILE view contains both datafile and control file records: a backup datafile 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 datafile records.

Column	Datatype	Description
`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.
`BCF_KEY`	`NUMBER`	The primary key of the control file 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 `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 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.
`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 backup control file.
`BS_LEVEL`	`NUMBER`	The incremental level (`NULL`, `0`, `1`, `2`) 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.
