| STAMP | NUMBER | The proxy copy stamp from V$PROXY_DATAFILE.RECIDandSTAMPform a concatenated primary key that uniquely identifies this record in the target database control file. | 
| TAG | VARCHAR2(32) | The tag for the proxy copy. | 
| RESETLOGS_CHANGE# | NUMBER | The RESETLOGSSCN of the database incarnation to which this data file belongs. | 
| RESETLOGS_TIME | DATE | The RESETLOGStime stamp of the database incarnation to which this data file belongs. | 
| CHECKPOINT_CHANGE# | NUMBER | Data file checkpoint SCN when this copy was made. | 
| CHECKPOINT_TIME | DATE | Data file checkpoint time when this copy was made. | 
| CREATION_TIME | DATE | The control file creation time. | 
| BLOCK_SIZE | NUMBER | The block size for the copy in bytes. | 
| BLOCKS | NUMBER | The number of blocks in the copy. | 
| MIN_OFFR_RECID | NUMBER | Internal use only. | 
| OLDEST_OFFLINE_RANGE | NUMBER | Internal use only. | 
| DEVICE_TYPE | VARCHAR2(255) | The type of sequential media device. | 
| HANDLE | VARCHAR2(1024) | The name or "handle" for the proxy copy. RMAN passes this value to the operating system-dependent layer that identifies the file. | 
| COMMENTS | VARCHAR2(255) | Comments about the proxy copy. | 
| 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 proxy copy is stored. |

| COMPLETION_TIME | DATE | The time when the proxy copy was completed. | 
| ELAPSED_SECONDS | NUMBER | The duration of the proxy copy. | 
| STATUS | VARCHAR2(1) | The status of the backup set: A(available),U(unavailable),X(expired), orD(deleted). | 
| KEEP | VARCHAR2(3) | Indicates whether this proxy copy has a retention policy different from the value for CONFIGURE RETENTION POLICY. Possible values areYESandNO. | 
| KEEP_OPTIONS | VARCHAR2(11) | The KEEPoptions specified for this control file backup. Possible values areNOLOGS,BACKUP_LOGS,LOGS, andNULL.NOLOGSindicates a consistent backup made when the database was mounted.BACKUP_LOGSindicates that the backup was made in open mode, so archived log backups must be applied to make it consistent.LOGSindicates a long-term backup made with theLOGSkeyword, which is now deprecated.NULLindicates that this backup has noKEEPoptions and becomes obsolete based on the retention policy. | 
| KEEP_UNTIL | DATE | If the KEEP UNTIL TIMEclause of theBACKUPcommand was specified, then this column shows the date after which this control file backup becomes obsolete. If the column isNULLandKEEP OPTIONSis notNULL, the backup never becomes obsolete. | 
| CONTROLFILE_TYPE | VARCHAR2(1) | The type of control file copy: B(normal copy) orS(standby copy). | 
| RSR_KEY | NUMBER | Unique key for the row in RC_RMAN_STATUSthat created this backup piece. | 
| 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_KEYvalue. You can useSITE_KEYin a join with theRC_SITEview to obtain theDB_UNIQUE_NAMEof the database. |
