5.15 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	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.
DB_ID	NUMBER	The database identifier.
PDB_KEY	NUMBER	The primary key of the PDB in the recovery catalog. Use this column to identify the PDB that owns the backup piece.
BP_KEY	NUMBER	The primary key for the backup piece 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 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 join with RC_BACKUP_SET, RC_BACKUP_CONTROLFILE, RC_BACKUP_DATAFILE, and so on.
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), L (archived redo log).
INCREMENTAL_LEVEL	NUMBER	The level of the incremental backup: NULL, 0, or 1.
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 file name 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 tag for the backup piece. Refer to description in BACKUP for default format for tag names.
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). Status D does not appear unless an older recovery catalog is upgraded.
BYTES	NUMBER	The size of the backup piece in bytes.
IS_RECOVERY_DEST_FILE	VARCHAR2(3)	This backup piece is located in the fast recovery area: YES or NO.
RSR_KEY	NUMBER	Unique key for the row in RC_RMAN_STATUS that created this backup piece.
COMPRESSED	VARCHAR2(3)	Indicates whether the backup piece is compressed (YES) or not (NO).
SITE_KEY	NUMBER	Primary key of the Data Guard database associated with this file. Each database in a Data Guard environment has a unique SITE_KEY value. You can use SITE_KEY in a join with the RC_SITE view to obtain the DB_UNIQUE_NAME of the database.
ENCRYPTED	VARCHAR2(3)	Indicates whether the backup piece is encrypted (YES) or not (NO).
BACKED_BY_OSB	VARCHAR2(3)	Indicates whether the backup piece is backed up to Oracle Secure Backup (YES) or not (NO).
BA_ACCESS	VARCHAR2(11)	Indicates how Zero Data Loss Recovery Appliance, commonly known as Recovery Appliance, will access the backup piece. This column is applicable only when RMAN is used with Recovery Appliance. The possible values are: Unknown: Recovery Appliance has no access to this backup piece Local: The backup piece is stored in an Recovery Appliance storage location Tape: The backup piece is accessible through an SBT interface installed on Recovery Appliance Disk: The backup piece is available on a disk that is accessible to Recovery Appliance
VB_KEY	NUMBER	The virtual backup ID. This value is NOT NULL if the backup piece is being dynamically built from the store location. Backup pieces with the same value for VB_KEY share a common source backup piece.
VIRTUAL	VARCHAR2(3)	Indicates if the backup piece can be dynamically built. Possible values are: Yes: The backup piece can be dynamically built from the backup storage location. No: The backup piece cannot be built from the backup storage location.
LIB_KEY	NUMBER	The library key of the SBT library defined on Recovery Appliance to which the backup piece is written.
