This view lists information about server parameter files in backup sets.
| Column | Data Type | Description | 
|---|---|---|
| DB_KEY | NUMBER | The primary key for the target database. Use this column to join with almost any other catalog view. | 
| BSF_KEY | NUMBER | The primary key of the server parameter file in the recovery catalog. If you issue the LISTcommand while RMAN is connected to the recovery catalog, then this value appears in theKEYcolumn of the output. | 
| RECID | NUMBER | The record identifier propagated from V$BACKUP_SPFILE.RECIDandSTAMPform a concatenated primary key that uniquely identifies this record in the target database control file. | 
| STAMP | NUMBER | The stamp from V$BACKUP_SPFILE.RECIDandSTAMPform 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. | 
| SET_STAMP | NUMBER | The SET_STAMPvalue fromV$BACKUP_SET.SET_STAMPandSET_COUNTform a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file. | 
| SET_COUNT | NUMBER | The SET_COUNTvalue fromV$BACKUP_SET.SET_STAMPandSET_COUNTform a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file. | 
| MODIFICATION_TIME | DATE | The time when the server parameter file was last modified. | 
| STATUS | VARCHAR2(1) | The status of the backup set: A(all backup pieces available),D(all backup pieces deleted),O(some backup pieces are available but others are not, so the backup set is unusable). | 
| BS_RECID | NUMBER | The RECIDvalue fromV$BACKUP_SET. | 
| BS_STAMP | NUMBER | The STAMPvalue fromV$BACKUP_SET.BS_STAMPis different fromSET_STAMP.BS_STAMPis the stamp of the backup set record when created in the control file, whereasSET_STAMPjoins withSET_COUNTto make a unique identifier. | 
| COMPLETION_TIME | DATE | The time when the backup set completed. | 
| BYTES | NUMBER | The size of the backup set in bytes. | 
| DB_UNIQUE_NAME | VARCHAR2(30) | The DB_UNIQUE_NAMEof the database to which this record belongs. |
