Recovery Catalog Views, 5 of 26


RC_BACKUP_DATAFILE

This view lists information about datafiles in backup sets. It corresponds to the V$BACKUP_DATAFILE view. A backup datafile is uniquely identified by BDF_KEY.

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. 

BDF_KEY 

NUMBER 

The primary key of the datafile backup 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 backup datafile RECID from V$BACKUP_DATAFILE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file. 

STAMP 

NUMBER 

The backup datafile stamp from V$BACKUP_DATAFILE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file. 

BS_KEY 

NUMBER 

The primary key of the backup set to which this record belongs in the recovery catalog. Use this column to form a join with RC_BACKUP_SET

SET_STAMP 

NUMBER 

The SET_STAMP value from V$BACKUP_SET. SET_STAMP and SET_COUNT form a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file. 

SET_COUNT 

NUMBER 

The SET_COUNT value from V$BACKUP_SET. SET_STAMP and SET_COUNT form a concatenated key that uniquely identifies the backup set to which this record belongs in the target database control file. 

BS_RECID 

NUMBER 

The RECID from V$BACKUP_SET

BS_STAMP 

NUMBER 

The STAMP from V$BACKUP_SET

BACKUP_TYPE 

VARCHAR2(1) 

The type of the backup: D (full or level 0 incremental) or I (incremental level 1 or higher). 

INCREMENTAL_LEVEL 

NUMBER 

The level of the incremental backup: NULL or 0 - 4. 

COMPLETION_TIME 

DATE 

The completion time of the backup. 

FILE# 

NUMBER 

The absolute file number of the datafile. 

CREATION_CHANGE# 

NUMBER 

The creation SCN of the datafile. 

RESETLOGS_CHANGE# 

NUMBER 

The SCN of the most recent RESETLOGS in the datafile header. 

RESETLOGS_TIME 

DATE 

The time stamp of the most recent RESETLOGS in the datafile header. 

INCREMENTAL_CHANGE# 

NUMBER 

The SCN that determines whether a block will be included in the incremental backup. A block is only included if the SCN in the block header is greater than or equal to INCREMENTAL_CHANGE#.

The range of redo covered by the incremental backup begins with INCREMENTAL_CHANGE# and ends with CHECKPOINT_CHANGE#

CHECKPOINT_CHANGE# 

NUMBER 

The checkpoint SCN of this datafile in this backup set. 

CHECKPOINT_TIME 

DATE 

The time associated with CHECKPOINT_CHANGE#

ABSOLUTE_FUZZY_CHANGE# 

NUMBER 

The absolute fuzzy SCN. 

DATAFILE_BLOCKS 

NUMBER 

The number of data blocks in the datafile. 

BLOCKS 

NUMBER 

The number of data blocks written to the backup. This value is often less than DATAFILE_BLOCKS because for full backups, blocks that have never been used are not included in the backup, and for incremental backups, blocks that have not changed are not included in the backup. This value is never greater than DATAFILE_BLOCKS

BLOCK_SIZE 

NUMBER 

The size of the data blocks in bytes. 

STATUS 

VARCHAR2(1) 

The status of the backup set: A (all pieces available), D (all pieces deleted), O (some pieces are available but others are not, so the backup set is unusable). 

BS_LEVEL 

NUMBER 

The incremental level (NULL or 0-4) specified when this backup was created. This value can be different from the INCREMENTAL_LEVEL column because if you run, for example, a level 2 incremental backup, but no previous level 0 backup exists for some files, a level 0 backup is automatically taken for these files. In this case, BS_LEVEL is 2 and INCREMENTAL_LEVEL is 0. 

PIECES 

NUMBER 

The number of backup pieces in the backup set that contains this backup datafile.
