RC_BACKUP_CONTROLFILE

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.

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.

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
