APAR status

  • Closed as program error.

Error description

  • OLDEST_COMMIT_LSN value in IBMQREP_APPLYMON gets reset to zero
    if there is a period of no activity and Q CAPTURE has sent a
    Heartbeat message.
    

Local fix

Problem summary

  • If Q APPLY has no outstanding transactions to
    be applied, and receives a Heartbeat message
    from Q Capture, it may cause the
    OLDEST_COMMIT_LSN value in IBMQREP_APPLYMON to
    be reported incorrectly as zero for that
    monitoring interval. This behavior is not as
    per product specifications.
    

Problem conclusion

  • Q APPLY has been fixed to prevent resetting
    OLDEST_COMMIT_LSN to zero while handling
    Heartbeat messages and will report the
    commit LSN of the last applied transaction
    instead.
