Description

SLG Parameters

Displays the service parameters that you can view or modify to generate Teradata WA SLG recommendations. Click a service parameter in the list or accept the default (Response Time) as appropriate.

When a listed parameter is selected:

  • this parameter appears as the horizontal axis of the chart
  • the value of this parameter can be edited in the SLG Recommendations table displayed beneath the chart; no other options are available for editing.
  • Changing the setting prompts Teradata WA to update the graph immediately.

    OpEnv

    Displays the available operating environment. Click operating environment (OpEnv) in the list box or accept Default as appropriate.

    Changing the setting prompts Teradata WA to update the graph immediately.

    Set Manually

    Allows modification of the recommended service levels. This checkbox is unchecked by default.

    Recommended SLG

    Changes the selected service parameter’s recommended value (shown highlighted in white). No other values are available for editing (shown shaded).

    Arrival rate, Response Time, Throughput and Service Percent are displayed. The response time goal shown is the value that would satisfy a 80% goal.

    Recommend on current Service percent

    Displays the current performance baseline that Teradata WA automatically uses for determining service level recommendations. Adjust this as appropriate.

    Factor by

    Modifies the SLG parameter, with a factor of 1 being the same as today, 0.1 being 10 times faster than today, 10.0 being 10 times slower than today.

    4 When satisfied with the new values, click Apply.
