RC_ARCHIVED

5.2 RC_ARCHIVED_LOG

This view contains historical information about archived and unarchived redo log files. 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. If a log that has not been archived is cleared, then a record is inserted with the NAME column set to NULL. If the log is archived multiple times, then the view contains 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. An archived log can have no record if the record ages out of the control file.

Column	Data Type	Description
`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 to which this record belongs. 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.
`AL_KEY`	`NUMBER`	The primary key of the archived redo log 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 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 file name 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`, then 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.
`IS_RECOVERY_DEST_FILE`	`VARCHAR2(3)`	This copy is located in the fast recovery area: `YES` or `NO`.
`COMPRESSED`	`VARCHAR2(3)`	Internal only
`CREATOR`	`VARCHAR2(7)`	Creator of the archived redo log: `ARCH` - Archiver process `FGRD` - Foreground process `RMAN` - Recovery Manager `SRMN` - RMAN at standby `LGWR` - Log Writer process
`TERMINAL`	`VARCHAR2(3)`	Indicates whether this log was created during terminal recovery of a standby database. Values are `YES` or `NO`.
`SITE_KEY`	`NUMBER`	Primary key of the Data Guard database associated with this file. Each database in a Data Guard environment has a unique `SITE_KEY` value. You can use `SITE_KEY` in a join with the `RC_SITE` view to obtain the `DB_UNIQUE_NAME` of the database.
