RC_BACKUP_REDOLOG

This view lists information about archived redo logs in backup sets. It corresponds to the V$BACKUP_REDOLOG view.

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.

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.
BRL_KEY NUMBER The primary key of the archived redo log 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 record identifier propagated from V$BACKUP_REDOLOG. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
STAMP NUMBER The stamp from V$BACKUP_REDOLOG. 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.
BACKUP_TYPE VARCHAR2(1) The type of the backup: L (archived redo log).
COMPLETION_TIME DATE The time when the backup completed.
THREAD# NUMBER The thread number of the redo log.
SEQUENCE# NUMBER The log sequence number.
RESETLOGS_CHANGE# NUMBER The SCN of the most recent RESETLOGS when the record was created.
RESETLOGS_TIME DATE The time stamp of the most recent RESETLOGS when the record was created.
FIRST_CHANGE# NUMBER The SCN generated when Oracle switched into the redo log.
FIRST_TIME DATE The time when Oracle switched into the redo log.
NEXT_CHANGE# NUMBER The first SCN of the next redo log in the thread.
NEXT_TIME DATE The first time stamp of the next redo log in the thread.
BLOCKS NUMBER The number of operating system blocks written to the backup.
BLOCK_SIZE NUMBER The number of bytes in each block of this redo log.
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_RECID NUMBER The RECID value from V$BACKUP_SET.
BS_STAMP NUMBER The STAMP value from V$BACKUP_SET. Note that BS_STAMP is different from SET_STAMP. BS_STAMP is the stamp of the backup set record when created in the control file, whereas SET_STAMP joins with SET_COUNT to make a unique identifier.
PIECES NUMBER The number of pieces in the backup set.
