This screen provides information about transaction performance.

    The following information is examined:

    o  Ratio of verb successes to verb failures

    o  95th percentile transaction duration

    Information in the Transaction Analysis screen is displayed
    only if it exceeds established threshold values or normal
    expectations. Note that the items identified in this screen are
    not necessarily indications of performance problems. The items
    may be an indication of a performance problem, but in most cases,
    further research is necessary.

    The Transaction Analysis screen has a configuration submenu that
    allows you to set thresholds for the following:

    o  Verb success threshold

       The default threshold is 25. You can override the default
       value with the RDM$BIND_STATS_VERB_SUCCESS_RATIO logical name.

    o  Transaction duration threshold

       The default threshold is 15. You can override the default
       value with the RDM$BIND_STATS_MAX_TX_DURATION logical name.

    o  Read/Write Transaction duration threshold

    o  Read-Only Transaction duration threshold

       The default threshold is 15 seconds. You can override the
       default value with the RDM$BIND_STATS_MAX_RO_TX_DURATION
       logical name.

    o  Transaction duration percentile

       The default threshold is 95. You can override the default
       value with the RDM$BIND_STATS_MAX_TX_PERCENTILE logical name.

    o  Read/Write Transaction duration percentile

    o  Read-Only Transaction duration percentile

       The default threshold is 95. You can override the default
       value with the RDM$BIND_STATS_MAX_RO_TX_PERCENTILE logical
       name.

    Note that the Online Analysis facility uses the actual database
    parameters and attributes specified using interactive SQL. The
    Online Analysis facility does not use the Dashboard facility
    because the Database Dashboard attributes are temporary settings.
    Therefore, online changes made using the Dashboard facility are
    not reflected in the analysis output. Yet, using the Dashboard
    facility is the recommended method for testing potential database
    attribute settings. You must use interactive SQL in order to make
    the attribute settings persistent.

    Also note that the Online Analysis facility is invoked at the
    designated screen refresh interval. As the Online Analysis
    facility is fairly CPU intensive, and the analysis results seldom
    vary greatly over a miniscule period of time, it is recommended
    that the screen refresh interval be set to 3 seconds or more.

    The Transaction Analysis screen is not recorded in the binary
    output file produced using the Output qualifier. Consequently,
    this screen is not available when you replay a binary file using
    the Input qualifier.
