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 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.
