Error description

  • On the AIX platform the latch wait times reported by monitor
    interfaces may not be accurate.
    
    The LATCH_WAIT_TIME monitor element reported by the
    MON_GET_LATCH table function may incorrectly report a latch wait
    time that is significantly larger than the actual latch wait
    time and the TOTAL_EXTENDED_LATCH_WAIT_TIME monitor element
    reported by various monitor interfaces such as MON_GET_ACTIVITY
    and MON_GET_CONNECTION may report a value that is significantly
    lower than the actual latch wait time. These inaccuracies may
    result in difficulty for both users and support diagnosing
    performance related issues.
