Oracle 视图 V$FOREIGN_ARCHIVED_LOG 官方解释，作用，如何使用详细说明

RECID

NUMBER

Archived log record ID

STAMP

NUMBER

Archived log record stamp

NAME

VARCHAR2(513)

Archived log file name. If set to NULL, either the log file was cleared before it was archived or an RMAN BACKUP command with the delete input option was executed to back up archivelog all (RMAN> backup archivelog all delete input;).

DEST_ID

NUMBER

Original destination from which the archive log was generated. The value is 0 if the destination identifier is not available

THREAD#

NUMBER

Redo thread number

SEQUENCE#

NUMBER

Redo log sequence number

RESETLOGS_CHANGE#

NUMBER

Resetlogs change number of the database when the log was written

RESETLOGS_TIME

DATE

Resetlogs time of the database when the log was written

RESETLOGS_ID

NUMBER

Resetlogs identifier associated with the archived redo log

FIRST_CHANGE#

NUMBER

First change number in the archived log

FIRST_TIME

DATE

Timestamp of the first change

NEXT_CHANGE#

NUMBER

First change in the next log

NEXT_TIME

DATE

Timestamp of the next change

BLOCKS

NUMBER

Size of the archived log (in blocks)

BLOCK_SIZE

NUMBER

Redo log block size. This is the logical block size of the archived log, which is the same as the logical block size of the online log from which the archived log was copied. The online log logical block size is a platform-specific value that is not adjustable by the user.

CREATOR

VARCHAR2(7)

Creator of the archive log:

ARCH – Archiver process

FGRD – Foreground process

RMAN – Recovery Manager

SRMN – RMAN at standby

LGWR – Logwriter process

REGISTRAR

VARCHAR2(7)

Registrar of the entry:

RFS – Remote File Server process

ARCH – Archiver process

FGRD – Foreground process

RMAN – Recovery Manager

SRMN – RMAN at standby

LGWR – Logwriter process

ARCHIVED

VARCHAR2(3)

Indicates whether the online redo log was archived (YES) or whether RMAN only inspected the log and created a record for future application of redo logs during recovery (NO).

APPLIED

VARCHAR2(3)

Indicates whether the archivelog has been applied to its corresponding standby database (YES) or not (NO). The value is always NO for local destinations.

This column is meaningful at the standby site for the ARCHIVED_LOG entries with REGISTRAR='RFS' (which means this log is shipped from the primary to the standby database). If REGISTRAR='RFS' and APPLIED is NO, then the log has arrived at the standby but has not yet been applied. If REGISTRAR='RFS' and APPLIED is YES, the log has arrived and been applied at the standby database.

You can use this field to identify archivelogs that can be backed up and removed from disk.

DELETED

VARCHAR2(3)

Indicates whether an RMAN DELETE command has physically deleted the archived log file from disk, as well as logically removing it from the control file of the target database and from the recovery catalog (YES) or not (NO)

STATUS

VARCHAR2(1)

Status of the archived log:

A – Available

D – Deleted

U – Unavailable

X – Expired

COMPLETION_TIME

DATE

Time when the archiving completed

DICTIONARY_BEGIN

VARCHAR2(3)

Indicates whether the log contains the start of a LogMiner dictionary (YES) or not (NO)

DICTIONARY_END

VARCHAR2(3)

Indicates whether the log contains the end of a LogMiner dictionary (YES) or not (NO)

END_OF_REDO

VARCHAR2(3)

Indicates whether the archived redo log contains the end of all redo information from the primary database () or not ()

ARCHIVAL_THREAD#

NUMBER

Redo thread number of the instance that performed the archival operation. This column differs from the THREAD# column only when a closed thread is archived by another instance.

IS_RECOVERY_DEST_FILE

VARCHAR2(3)

Indicates whether the file was created in the fast recovery area (YES) or not (NO)

COMPRESSED

VARCHAR2(3)

Reserved for internal use

FAL

VARCHAR2(3)

Indicates whether the archive log was generated as the result of a FAL request (YES) or not (NO)

END_OF_REDO_TYPE

VARCHAR2(10)

Possible values are as follows:

SWITCHOVER – Shows archived redo log files that are produced at the end of a switchover

TERMINAL – Shows archived redo log files produced after a failover

RESETLOGS – Shows online redo log files archived on the primary database after an ALTER DATABASE OPEN RESETLOGS statement is issued

ACTIVATION – Shows any log files archived on a physical standby database after an ALTER DATABASE ACTIVATE STANDBY DATABASE statement is issued

“empty string” – Any empty string implies that the log is just a normal archival and was not archived due to any of the other events

SOURCE_DBID

NUMBER

Database ID of the source database that generated this archived log

CON_ID

NUMBER

The ID of the container to which the data pertains. Possible values include:

• 0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.

• 1: This value is used for rows containing data that pertain to only the root

• n: Where n is the applicable container ID for the rows containing data
