V$PROXY_DATAFILE

V$PROXY_DATAFILE contains descriptions of datafile and control file backups that are taken with Proxy Copy. Each row represents a backup of one database file.

Column	Datatype	Description
`RECID`	`NUMBER`	Proxy copy record ID
`STAMP`	`NUMBER`	Proxy copy record stamp
`DEVICE_TYPE`	`VARCHAR2(17)`	Type of the device on which the copy resides
`HANDLE`	`VARCHAR2(513)`	Proxy copy handle identifies the copy for restore
`COMMENTS`	`VARCHAR2(81)`	Comment returned by the operating system or storage subsystem. This value is informational only. It is not needed for restore.
`MEDIA`	`VARCHAR2(65)`	Name of the media on which the copy resides. This value is informational only. It is not needed for restore.
`MEDIA_POOL`	`NUMBER`	Media pool in which the copy resides. This is the same value that was entered in the `POOL` operand of the Recovery Manager `BACKUP` command
`TAG`	`VARCHAR2(32)`	Proxy copy tag
`STATUS`	`VARCHAR2(1)`	Status of the backup set: `A` - Available `U` - Unavailable `X` - Expired `D` - Deleted
`DELETED`	`VARCHAR2(3)`	Indicates whether this record has been deleted (`YES`) or not (`NO`)
`FILE#`	`NUMBER`	Absolute datafile number, or 0 if this is a control file backup
`CREATION_CHANGE#`	`NUMBER`	Datafile creation change number
`CREATION_TIME`	`DATE`	Datafile creation Timestamp
`RESETLOGS_CHANGE#`	`NUMBER`	Resetlogs change number of the datafile when the copy was made
`RESETLOGS_TIME`	`DATE`	Resetlogs timestamp of the datafile when the copy was made
`CHECKPOINT_CHANGE#`	`NUMBER`	Checkpoint change number of the datafile when the copy was made
`CHECKPOINT_TIME`	`DATE`	Checkpoint timestamp of the datafile when the copy was made
`ABSOLUTE_FUZZY_CHANGE#`	`NUMBER`	Highest change in any block of the file, if known
`RECOVERY_FUZZY_CHANGE#`	`NUMBER`	Highest change written to the file by media recovery
`RECOVERY_FUZZY_TIME`	`DATE`	Timestamp of the highest change written to the file by media recovery
`INCREMENTAL_LEVEL`	`NUMBER`	If this backup is part of an incremental backup strategy, then 0. Otherwise null.
`ONLINE_FUZZY`	`VARCHAR2(3)`	Indicates whether this copy was made after a crash or offline immediate (or is a copy of a copy which was taken improperly while the database was open) (`YES`) or not (`NO`). Recovery will need to apply all redo up to the next crash recovery marker to make the file consistent.
`BACKUP_FUZZY`	`VARCHAR2(3)`	Indicates whether this is a copy taken using the `BEGIN BACKUP \| END BACKUP` technique (`YES`) or not (`NO`). The `BEGIN BACKUP \| END BACKUP` technique is used internally when proxy copies of open files are created. Recovery will need to apply all redo up to the end backup marker to make this copy consistent.
`BLOCKS`	`NUMBER`	Size of the copy (in blocks). Also the size of the datafile when the copy was made.
`BLOCK_SIZE`	`NUMBER`	Block size of the datafile
`OLDEST_OFFLINE_RANGE`	`NUMBER`	If the file number is `0` (that is, this is a control file backup), the RECID of the oldest offline range record in this control file copy. `0` for datafile copies.
`START_TIME`	`DATE`	Starting time
`COMPLETION_TIME`	`DATE`	Completion time
`ELAPSED_SECONDS`	`NUMBER`	Number of elapsed seconds
`CONTROLFILE_TYPE`	`VARCHAR2(1)`	Type of control file: `B` - Normal control file `S` - Standby control file
`KEEP`	`VARCHAR2(3)`	Indicates whether this backup set has a retention policy that is different than the value for the configure retention policy (`YES`) or not (`NO`)
`KEEP_UNTIL`	`DATE`	If specified, then this is the date after which the backup becomes obsolete. If this column is NULL, then the backup never expires.
`KEEP_OPTIONS`	`VARCHAR2(11)`	Additional retention options for this backup set: `LOGS` - Indicates a long-term backup made with the `LOGS` keyword, which is now deprecated `BACKUP_LOGS` - Indicates that the backup was made in open mode, so archived log backups must be applied to make it consistent `NOLOGS` - Indicates a consistent backup made when the database was mounted. NULL - Indicates that this backup has no `KEEP` options and becomes obsolete based on the retention policy
`RMAN_STATUS_RECID`	`NUMBER`	Owning `V$RMAN_STATUS` record ID
`RMAN_STATUS_STAMP`	`NUMBER`	Owning `V$RMAN_STATUS` stamp
`FOREIGN_DBID`	`NUMBER`	Foreign DBID of the database from which this datafile was transported. The value is `0` if the file backed up is not a foreign database file.
`PLUGGED_READONLY`	`VARCHAR2(3)`	Indicates whether this is a proxy copy of a transported read-only foreign file (`YES`) or not (`NO`)
`PLUGIN_CHANGE#`	`NUMBER`	SCN at which the foreign datafile was transported into the database. The value is `0` if this file is not a foreign database file.
`PLUGIN_RESETLOGS_CHANGE#`	`NUMBER`	SCN of the `RESETLOGS` operation for the incarnation into which this foreign file was transported. The value is `0` if this file is not a foreign database file.
`PLUGIN_RESETLOGS_TIME`	`DATE`	Time of the `RESETLOGS` operation for the incarnation into which this foreign file was transported. The value is `0` if this file is not a foreign database file.
`CON_ID`	`NUMBER`	The ID of the container to which the data pertains. Possible values include: `0`: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs. `1`: This value is used for rows containing data that pertain to only the root n: Where n is the applicable container ID for the rows containing data
`BACKED_BY_PDB`	`VARCHAR2(3)`	Recovery Manager (RMAN) allows a PDB to be backed up in two ways. The value in this column indicates how the PDB backup was taken: `YES`: The backup was taken when connected to the PDB `NO`: The backup was taken when connected to the root container
