# RC_PROXY_CONTROLFILE

This view contains descriptions of control file backups that were taken using the proxy copy functionality. It corresponds to the `V$PROXY_DATAFILE` view.

In a proxy copy, the media manager takes over the operations of backing up and restoring data. Each row represents a backup of one control file.

Column | Datatype | Description
--- | --- | ---
`DB_KEY` | `NUMBER` | The primary key for the target database. Use this column to form a join with almost any other catalog view.
`DBINC_KEY` | `NUMBER` | The primary key for the incarnation of the target database. Use this column to form a join with `RC_DATABASE_INCARNATION`.
`DB_NAME` | `VARCHAR2(8)` | The `DB_NAME` of the database incarnation to which this record belongs.
`XCF_KEY` | `NUMBER` | The proxy copy primary key in the recovery catalog. If you issue the `LIST` command while connected to the recovery catalog, this value appears in the `KEY` column of the output.
`RECID` | `NUMBER` | The proxy copy record identifier from `V$PROXY_DATAFILE.` `RECID` and `STAMP` form a concatenated primary key that uniquely identifies this record in the target database control file.
`STAMP` | `NUMBER` | The proxy copy stamp from`V$PROXY_DATAFILE. RECID` and `STAMP` form 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 `RESETLOGS` SCN of the database incarnation to which this datafile belongs.
`RESETLOGS_TIME` | `DATE` | The `RESETLOGS` time stamp of the database incarnation to which this datafile belongs.
`CHECKPOINT_CHANGE#` | `NUMBER` | Datafile checkpoint SCN when this copy was made.
`CHECKPOINT_TIME` | `DATE` | Datafile 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.
`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.
`START_TIME` | `DATE` | The time when proxy copy was initiated.
`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), or `D` (deleted).
`KEEP` | `VARCHAR2(3)` | Indicates whether this proxy copy has a retention policy different from the value for `CONFIGURE` `RETENTION` `POLICY`. Possible values are `YES` and `NO`.
`KEEP_OPTIONS` | `VARCHAR2(10)` | The `KEEP` options specified for this control file backup. Options can be `LOGS` (RMAN keeps the logs needed to recover this backup), `NOLOGS` (RMAN does not keep the logs needed to recover this backup), or `NULL` (the backup has no `KEEP` options and will be made obsolete based on the retention policy).
`KEEP_UNTIL` | `DATE` | If the `KEEP` `UNTIL TIME` clause of the `BACKUP` command was specified, then this column shows the date after which this control file backup becomes obsolete. If the column is `NULL` and `KEEP` `OPTIONS` is not `NULL`, the backup never becomes obsolete.
`CONTROLFILE_TYPE` | `VARCHAR2(1)` | The type of control file copy: `B` (normal copy) or `S` (standby copy).
