RC_BACKUP_PIECE_DETAILS

RC_BACKUP_PIECE_DETAILS contains detailed information about all available backup pieces recorded in the recovery catalog. The semantics of most columns duplicate the RC_BACKUP_PIECE recovery catalog view.

This view is primarily intended to be used internally by Enterprise Manager.

Column Data Type Description
SESSION_KEY NUMBER Session identifier. Use in joins with RC_RMAN_OUTPUT and RC_RMAN_BACKUP_JOB_DETAILS.
SESSION_RECID NUMBER With SESSION_STAMP, uniquely identifies output for this backup job from RC_RMAN_OUTPUT.
SESSION_STAMP NUMBER With SESSION_RECID, uniquely identifies output for this backup job from RC_RMAN_OUTPUT.
DB_NAME VARCHAR2(8) The DB_NAME of the database incarnation to which this record belongs.
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 DBID of the database incarnation to which this record belongs.
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 RC_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$BACKUP_PIECE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
BS_KEY NUMBER The primary key of the backup set to which this record belongs in the recovery catalog. Use this column to join with RC_BACKUP_SET or RC_BACKUP_PIECE.
SET_STAMP NUMBER The SET_STAMP value from V$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.
BACKUP_TYPE VARCHAR2(1) The type of backup. Possible values are D for data file or control file backups, I for incremental backups, and L for archived log file backups.
INCREMENTAL_LEVEL NUMBER For incremental backups, indicates the level of incremental backup. Possible values are NULL (for full backups), 0 or 1.
PIECE# NUMBER The number of the backup piece. The first piece has the value of 1.
COPY# NUMBER Indicates the copy number for backup pieces created with duplex enabled. 1 if the backup piece is not duplexed.
DEVICE_TYPE VARCHAR2(255) Type of the device on which the backup piece resides. Set to DISK for backup sets on 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. 0 indicates no media pool.
CONCUR VARCHAR2(3) Specifies whether backup media supports concurrent access: YES or NO.
TAG VARCHAR2(32) The tag associated with this 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 for backup pieces that are AVAILABLE. (The value is always A, because this view shows only available backup pieces.)
BYTES NUMBER The size of the backup piece in bytes.
IS_RECOVERY_DEST_FILE VARCHAR2(3) YES if this backup piece is located in the fast recovery area. NO otherwise.
RSR_KEY NUMBER Unique key for the row in RC_RMAN_STATUS corresponding to the job that created this backup piece.
COMPRESSED VARCHAR2(3) YES if this backup piece is compressed. NO otherwise.
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).
PIECES_PER_SET NUMBER Number of backup pieces in the backup set containing this backup piece.
SIZE_BYTES_DISPLAY VARCHAR2(32K) Same value as BYTES, but converted to a user-displayable format, for example, 798.01M or 5.25G.
