DB_KEY |
NUMBER |
The primary key for this database in the recovery catalog. Use this column to join with almost any other catalog view. |
DBINC_KEY |
NUMBER |
The primary key for the incarnation of the target database. Use this column to 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 RMAN is connected to the recovery catalog, then 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 join with RC_BACKUP_SET or RC_BACKUP_PIECE. |
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). |
INCREMENTAL_LEVEL |
NUMBER |
The level of the incremental backup: NULL, 0, or 1. |
COMPLETION_TIME |
DATE |
The completion time of the backup. |
FILE# |
NUMBER |
The absolute file number of the datafile. Note that when FILE#=0, the record refers to the control file. See the note following this table for special semantics of other columns when FILE#=0. |
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. See the note following this table for special semantics when FILE#=0. |
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, 0, or 1) specified when this backup was created. This value can be different from the INCREMENTAL_LEVEL column because if you run, for example, a level 1 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 1 and INCREMENTAL_LEVEL is 0. |
PIECES |
NUMBER |
The number of backup pieces in the backup set that contains this backup datafile. |
BLOCKS_READ |
NUMBER |
Number of blocks that were scanned while taking this backup. If this was an incremental backup, and change tracking was used to optimize the backup, then the value of this column will be smaller than DATAFILE_BLOCKS. Otherwise, the value of this column will be the same as DATAFILE_BLOCKS. Even when change tracking data is used, the value of this column may be larger than BLOCKS, because the data read by change tracking is further refined during the process of creating an incremental backup. |
CREATION_TIME |
DATE |
Creation timestamp of the datafile. |
MARKED_CORRUPT |
NUMBER |
Number of blocks marked corrupt. |
USED_CHANGE_TRACKING |
VARCHAR2(3) |
Whether change tracking data was used to accelerate this incremental backup (YES) or was not used (NO). |
USED_OPTIMIZATION |
VARCHAR2(3) |
Whether backup optimization was applied (YES) or not (NO). |
PCT_NOTREAD |
NUMBER |
The percentage of the file that was skipped during this backup. For incremental backups, this value indicates the efficiency of the block change tracking file. |
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) |
YES if this is a backup of 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. |
SECTION_SIZE |
NUMBER |
Specifies the number of blocks in each section of a multisection backup. Value is 0 for whole file backups. |
