This chapter contains descriptions of recovery catalog views. You can only access these views if you have created a recovery catalog.
This view lists historical information about all archived redo logs. It corresponds to the V$ARCHIVED_LOG dynamic performance view in the control file.
An archived redo log record is inserted after the online redo log is successfully archived or cleared (NAME column is NULL if the log was cleared). If the log is archived multiple times (the maximum is 5), there will be multiple archived log records with the same THREAD#, SEQUENCE#, and FIRST_CHANGE#, but with a different name. An archived log record is also inserted when an archived log is restored from a backup set or a copy.
Note that an archived redo log can have no log history record if its log history record is written over in the control file or after a RESETLOGS operation.
This view lists information about control files in backup sets. Note that a backup datafile record with file number 0 represents the backup control file in the V$BACKUP_DATAFILE dynamic performance view.
This view lists corrupt block ranges in datafile backups. It corresponds to the V$BACKUP_CORRUPTION dynamic performance view in the control file. Note that corruptions are not tolerated in control file and archived redo log backups.
This view lists information about datafiles in backup sets. It corresponds to the V$BACKUP_DATAFILE dynamic performance view. A backup datafile is uniquely identified by BDF_KEY.
This view lists information about backup pieces. This view corresponds to the V$BACKUP_PIECE dynamic performance view. Each backup set contains one or more backup pieces.
Multiple copies of the same backup piece can exist, but each copy will have its own record in the control file and its own row in the view.
This view lists information about archived redo logs in backup sets. It corresponds to the V$BACKUP_REDOLOG dynamic performance view in the control file.
You cannot back up online logs directly; you must first archive them to disk and then back them up. An archived log backup set contains one or more archived logs.
This view lists information about backup sets for all incarnations of the database. It corresponds to the V$BACKUP_SET dynamic performance view. A backup set record is inserted after the backup has successfully completed.
This view lists recovery catalog resynchronization information. It does not give information about database checkpoints. In most cases, you should use RC_RESYNC instead.
This view lists information about control file copies on disk. Note that a datafile copy record with a file number of 0 is used to represent the control file copy in the V$DATAFILE_COPY dynamic performance view.
This view lists corrupt block ranges in datafile copies. It corresponds to the V$COPY_CORRUPTION dynamic performance view.
This view gives information about the databases registered in the recovery catalog.
This view lists information about all database incarnations registered in the recovery catalog. Oracle creates a new incarnation whenever you open a database with the RESETLOGS option.
C
This view lists information about all datafiles registered in the recovery catalog. It corresponds to the V$DATAFILE dynamic performance view. A datafile is shown as dropped if its tablespace was dropped.
This view lists information about datafile copies on disk. It corresponds to the V$DATAFILE_COPY dynamic performance view.
