    Unanswered: SYsmaster database

    From one of the article, I get:

    database sysmaster;
    select
    dbsname,
    tabname,
    bufreads,
    pagreads
    deadlks
    from sysptprof
    order by deadlks desc;

    and the output (deadlks) is negative value. What does it mean?

    A negative value normally means an overflow.
    bufreads/bufwrites can reach very high values a heavy
    loaded system.

    So you need to make sure that you reset the statistics
    at regular intervals (onstat -z) in order to avoid
    any overflows.

    However for deadlocks there should not be an overflow.
    This makes no sense. I could not imagine that you have
    so much deadlocks in your system. I would consider
    this as an IFMX bug and call IFMX tech support.

    Best regards
