  • RFS

SCHEDULE

VARCHAR2(8)

Indicates whether the archival of this destination is INACTIVE, PENDING, ACTIVE, or LATENT

DESTINATION

VARCHAR2(256)

Specifies the location where the archived redo logs are to be archived

LOG_SEQUENCE

NUMBER

Identifies the sequence number of the last archived redo log to be archived

REOPEN_SECS

NUMBER

Identifies the retry time (in seconds) after error

DELAY_MINS

  • ARCn

  • FOREGROUND

  • LGWR

REGISTER

FAIL_DATE

DATE

Date and time of last error

FAIL_SEQUENCE

NUMBER

Sequence number of the archived redo log being archived when the last error occurred

FAIL_BLOCK

NUMBER

Block number of the archived redo log being archived when the last error occurred

FAILURE_COUNT

TRANSMIT_MODE

VARCHAR2(12)

Specifies network transmission mode:

  • PARALLELSYNC

  • ASYNCHRONOUS

ASYNC_BLOCKS

NUMBER

Number of blocks specified for the ASYNC attribute

AFFIRM

VARCHAR2(3)

Specifies disk I/O mode

TYPE

VARCHAR2(7)

Indicates whether the archived log destination definition is PUBLIC or PRIVATE. Only PUBLIC destinations can be modified at run time using the ALTER SYSTEM SET or ALTER SESSION SET statements. By default, all archived log destinations are PUBLIC.

VALID_NOW

VARCHAR2(16)

Indicates whether the destination is valid right now for archival operations:

  • YES - Redo log type and database role for this destination are valid for the current database

  • WRONG VALID_TYPE - Redo log type specified for this destination is not valid for the current database role. For example, WRONG VALID_TYPE would be returned if a destination specified with the VALID_FOR=(STANDBY_LOGFILE,STANDBY_ROLE) attribute is running in the standby database role but does not have standby redo logs implemented.

  • WRONG VALID_ROLE - Database role specified for this destination is not the role in which the database is currently running. For example, the WRONG VALID_ROLE would be returned when a destination defined with the VALID_FOR=(ONLINE_LOGFILE,STANDBY_ROLE) attribute is running in the primary database role.

  • INACTIVE - Destination is inactive, probably due to an error

VALID_TYPE

VARCHAR2(15)

Redo log type or types that are valid for the destination:

  • ONLINE_LOGFILE

  • STANDBY_LOGFILE

  • ALL_LOGFILES

VALID_ROLE

VARCHAR2(12)

Database role or roles that are valid for the destination:

  • PRIMARY_ROLE

  • STANDBY_ROLE

  • ALL_ROLES

DB_UNIQUE_NAME

VARCHAR2(30)

  • DISABLE: Compression is disabled.

  • ENABLE: Compression is enabled. The ZLIB compression algorithm is used.

  • ZLIB: ZLIB compression is used.

  • LZO: LZO compression is used.

APPLIED_SCN

NUMBER

For a destination that corresponds to a physical or logical standby database, the SCN of the last applied redo. For a destination that corresponds to a snapshot standby database, the SCN of the last redo applied before conversion to a snapshot standby database. This column is only valid for enabled and active standby database destinations on a primary or cascading standby database.

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.
