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.
