SendQEntries (Send Queue Entries)

The SendQEntries monitorable property returns a table that shows all log files on the primary database that were not successfully archived to one or more standby databases.

This property pertains to the primary database.

The table contains the following columns:

  • STANDBY_NAME

    The value can be empty or it can contain the database unique name (DB_UNIQUE_NAME) of a standby database. If empty, the STATUS column will contain a value of CURRENT or NOT_ARCHIVED.

  • STATUS

    The STATUS column is set to one of the following values:

    • CURRENT: A log file to which online redo is currently being written.

    • NOT_ARCHIVED: A completed online redo log file that has not been archived locally.

    • ARCHIVED: A completed log file that has been archived locally but has not been transmitted to the standby database specified in the STANDBY_NAME column.

    The table contains exactly one row with the value of STATUS=CURRENT. There can be multiple rows with the value STATUS=ARCHIVED or STATUS=NOT_ARCHIVED.

  • RESETLOGS_ID

    Resetlogs identifier associated with the archived redo log file

  • THREAD

    The redo thread number.

  • LOG_SEQ

    The log sequence number. Multiple rows may have the same LOG_SEQ value (for different STANDBY_NAME values).

  • TIME_GENERATED

    The first time when the online redo log file was written to the primary database.

  • TIME_COMPLETED

    The next time when the log file was archived on the primary database (corresponds to the NEXT_CHANGE# column).

  • FIRST_CHANGE#

    First change number in the archived redo log file.

  • NEXT_CHANGE#

    First change in the next log file.

  • SIZE (KBs)

    The SIZE of the online redo log file in kilobytes.

For example, the following shows output from a SHOW DATABASE command: 

DGMGRL> SHOW DATABASE 'North_Sales' 'SendQEntries' ;
PRIMARY_SEND_QUEUE
        STANDBY_NAME       STATUS     RESETLOGS_ID
THREAD              LOG_SEQ       TIME_GENERATED       TIME_COMPLETED
FIRST_CHANGE#     NEXT_CHANGE#       SIZE (KBs)
