V$DATAFILE_COPY

V$DATAFILE_COPY displays datafile copy information from the control file.

Column Datatype Description
RECID NUMBER Datafile copy record ID
STAMP NUMBER Datafile copy record stamp
NAME VARCHAR2(513) Filename of the datafile copy. The maximum length of the name is OS dependent.
TAG VARCHAR2(32) Datafile copy tag
FILE# NUMBER Absolute datafile number
RFILE# NUMBER Tablespace relative datafile number
CREATION_CHANGE# NUMBER Datafile creation change#
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
INCREMENTAL_LEVEL NUMBER Normal full backups have a NULL value, level 0 incremental backups have a value of 0, and level 1 incremental backups have a value of 1
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 seen when the datafile was copied
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
ONLINE_FUZZY VARCHAR2(3) (YES|NO) If set to YES, this is a copy taken using an operating system utility after a crash or offline immediate (or an invalid copy taken while datafile was online and the database open). Recovery will need to apply all redo up to the next crash recovery marker to make the file consistent.
BACKUP_FUZZY VARCHAR2(3) (YES|NO) If set to YES, this is a copy taken using the BEGIN BACKUP/END BACKUP technique. Recovery will need to apply all redo up to the end backup marker to make this copy consistent.
MARKED_CORRUPT NUMBER Number of blocks marked corrupt by this copy operation. That is, blocks that were not marked corrupted in the source datafile, but were detected and marked as corrupted during the copy operation.
MEDIA_CORRUPT NUMBER Total number of media corrupt blocks. For example, blocks with checksum errors are marked media corrupt.
LOGICALLY_CORRUPT NUMBER Total number of logically corrupt blocks. For example, applying redo for unrecoverable operations will mark affected blocks logically corrupt.
BLOCKS NUMBER Size of the datafile 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 RECID of the oldest offline range record in this control file copy; 0 for datafile copies
DELETED VARCHAR2(3) (YES|NO) If set to YES the datafile copy has been deleted or overwritten
STATUS VARCHAR2(1) Identifies the status of this datafile copy. Possible values are:

A - Available

D - Deleted

U - Unavailable

X - Expired

COMPLETION_TIME DATE Time when the copy was completed
CONTROLFILE_TYPE VARCHAR2(1) B indicates normal copies

S indicates standby copies

KEEP VARCHAR2(3) (YES/NO) Indicates whether or not this backup set has a retention policy that is different than the value for the configure retention policy
KEEP_UNTIL DATE If KEEP_UNTIL is specified, this is the date after which the backup becomes obsolete. If this column is null, then the backup never expires.
KEEP_OPTIONS VARCHAR2(10) Lists additional retention options for this backup set. Possible values are:

LOGS - The logs need to recover this backup are kept

NOLOGS - The logs needed to recover this backup will not be kept

SCANNED VARCHAR2(3) Indicates whether RMAN scanned the file (YES) or not (NO)
IS_RECOVERY_DEST_FILE VARCHAR2(3) Indicates whether the file was created in the fast recovery area (YES) or not (NO)
RMAN_STATUS_RECID NUMBER Owning V$RMAN_STATUS record ID
RMAN_STATUS_STAMP NUMBER Owning V$RMAN_STATUS record stamp
CONVERTED_FILE VARCHAR2(3) (YES/NO) Indicates whether or not the datafile copy was created using the RMAN CONVERT command
SAME_ENDIAN VARCHAR2(3) If the value of the CONVERTED_FILE column is YES, then this column indicates whether the datafile copy has the same endianness as the source datafile (YES) or not (NO); otherwise NULL
FOREIGN_DBID NUMBER Foreign DBID from which this data file came from. The value is 0 if this file is not a foreign database file.
PLUGGED_READONLY VARCHAR2(3) YES if this is a transported read-only foreign file; otherwise 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 The 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 The 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.
BACKED_BY_VSS VARCHAR2(3) Whether or not the file has been backed up by Volume Shadow Copy Service (VSS). This column is reserved for internal use.
