This view 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; not needed for restore. 

MEDIA

STATUS 

VARCHAR2(1) 

Indicates the status of the copy:

  • A - The object is available

  • D - The object is deleted

  • X - The object has been "cross-checked" and found not to exist. A subsequent "delete expired" command will change the status to D. If, for some reason, the object really does still exist, then a subsequent "cross-check" command will change the status back to A.

 

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

ABSOLUTE_FUZZY_CHANGE# 

NUMBER

RECOVERY_FUZZY_CHANGE# 

NUMBER

RECOVERY_FUZZY_TIME 

DATE

INCREMENTAL_LEVEL 

NUMBER 

0 if this backup is part of an incremental backup strategy, otherwise NULL 

ONLINE_FUZZY 

VARCHAR2(3) 

(YES|NO) If set to YES, 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). 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. Note that 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 file# is 0 (ie, 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

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
