RC_CONTROLFILE_COPY

This view lists information about control file copies on disk. A datafile copy record with a file number of 0 represents the control file copy in V$DATAFILE_COPY.

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.

DB_NAME VARCHAR2(8) The DB_NAME of the database incarnation to which this record belongs.
CCF_KEY NUMBER The primary key of the control file copy 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 record identifier from V$DATAFILE_COPY. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
STAMP NUMBER The stamp from V$DATAFILE_COPY. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
NAME VARCHAR2(1024) The control file copy filename.
TAG VARCHAR2(32) The tag of the control file copy. NULL if no tag used.
RESETLOGS_CHANGE# NUMBER The SCN of the most recent RESETLOGS when the record was created.

KEEP VARCHAR2(3) Indicates whether this copy has a retention policy different from the value for CONFIGURE RETENTION POLICY. Possible values are YES and NO.
KEEP_UNTIL DATE If the KEEP UNTIL TIME clause of the COPY command was specified, then this column shows the date after which this file becomes obsolete. If the column is NULL and KEEP OPTIONS is not NULL, the file never becomes obsolete.
KEEP_OPTIONS VARCHAR2(10) The KEEP options specified for this control file copy. Options can be LOGS (RMAN keeps the logs needed to recover this backup), NOLOGS (RMAN does not keep the logs needed to recover this backup), or NULL (the backup has no KEEP options and is subject to the default retention policy).
IS_RECOVERY_DEST_FILE VARCHAR2(3) This copy is located in the flash recovery area: YES or NO.
