RC_BACKUP_PIECE

This view lists information about backup pieces. This view corresponds to the V$BACKUP_PIECE view. Each backup set contains one or more backup pieces.

Multiple copies of the same backup piece can exist, but each copy has its own record in the control file and its own row in the view.

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_ID	NUMBER	The database identifier.
BP_KEY	NUMBER	The primary key for the backup piece 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 backup piece RECID from V$BACKUP_PIECE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
STAMP	NUMBER	The backup piece stamp propagated from V$BACKUP_PIECE. 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.
BACKUP_TYPE	VARCHAR2(1)	The type of the backup: D (full or level 0 incremental), I (incremental level 1 or higher), L (archived redo log).
INCREMENTAL_LEVEL	NUMBER	The level of the incremental backup: NULL or 0 - 4.
PIECE#	NUMBER	The number of the backup piece. The first piece has the value of 1.
COPY#	NUMBER	The copy number of the backup piece.
DEVICE_TYPE	VARCHAR2(255)	The type of backup device, for example, DISK.
HANDLE	VARCHAR2(1024)	The filename of the backup piece.
COMMENTS	VARCHAR2(255)	Comments about the backup piece.
MEDIA	VARCHAR2(80)	A comment that contains further information about the media manager that created this backup.
MEDIA_POOL	NUMBER	The number of the media pool in which the backup is stored.
CONCUR	VARCHAR2(3)	Specifies whether backup media supports concurrent access: YES or NO.
TAG	VARCHAR2(32)	The user-specified tag for the backup piece.
START_TIME	DATE	The time when RMAN started to write the backup piece.
COMPLETION_TIME	DATE	The time when the backup piece was completed.
ELAPSED_SECONDS	NUMBER	The duration of the creation of the backup piece.
STATUS	VARCHAR2(1)	The status of the backup piece: A (available), U (unavailable), D (deleted), or X (expired). Note that status D will not appear in Oracle9i unless an older recovery catalog is upgraded.
