RC_ARCHIVED_LOG

This view contains historical information about archived and unarchived redo logs. It corresponds to the V$ARCHIVED_LOG view in the target database control file.

Oracle inserts an archived redo log record 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, then the view will contain multiple archived log records with the same THREAD#, SEQUENCE#, and RESETLOGS_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 log can have no record if the record ages out of the control file.

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 to which this record belongs. 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.
AL_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 archived redo log RECID from V$ARCHIVED_LOG. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
STAMP	NUMBER	The archived redo log stamp from V$ARCHIVED_LOG. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.
NAME	VARCHAR2(1024)	The filename of the archived redo log.
THREAD#	NUMBER	The number of the redo thread.
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 first SCN of this 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 size of this archived log in operating system blocks.
BLOCK_SIZE	NUMBER	The size of the block in bytes.
COMPLETION_TIME	DATE	The time when the redo log was archived or copied.
ARCHIVED	VARCHAR2(3)	Indicates whether the log was archived: YES (archived redo log) or NO (inspected file header of online redo log and added record to V$ARCHIVED_LOG). Inspecting the online logs creates archived log records for them, which allows them to be applied during RMAN recovery. Oracle sets ARCHIVED to NO to prevent online logs from being backed up.
STATUS	VARCHAR2(1)	The status of the archived redo log: A (available), U (unavailable), D (deleted), or X (expired).
IS_STANDBY	VARCHAR2(3)	The database that archived this log: Y (belongs to a standby database) or N (belongs to the primary database).
DICTIONARY_BEGIN	VARCHAR2(3)	Indicates whether this archived log contains the start of a LogMiner dictionary: YES or NO. If both DICTIONARY_BEGIN and DICTIONARY_END are YES, this log contains a complete LogMiner dictionary. If DICTIONARY_BEGIN is YES but DICTIONARY_END is NO, this log contains the start of the dictionary, and it continues through each subsequent log of this thread and ends in the log where DICTIONARY_END is YES.
DICTIONARY_END	VARCHAR2(3)	Indicates whether this archived log contains the end of a LogMiner dictionary: YES or NO. See the description of DICTIONARY_BEGIN for an explanation of how to interpret this value.
