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. |

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. |

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 |

The size of the backup piece in bytes. |
IS_RECOVERY_DEST_FILE |
VARCHAR2(3) |

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. |
