Screen Description

The Interval Information screen displays an overview of DC statistics by interval. Use this screen to quickly compare activity across intervals.

Using this Screen

To access the Specific Interval Information screen for DC statistics for a particular interval, type any nonblank character to the left of the interval for which the detail is required and press [Enter].

What To Look For

• Look for intervals with unusually high levels of activity compared to other intervals.
• Look for intervals with high numbers of task abends. Increases in task abends reduces the number of tasks processed and increases the CPU used by the DC/UCF system to format and write dumps to the log. Look at the system log (by using OLP or the PRINT LOG utility) to identify tasks that are abending.
• Look at the Times_At_Max field. If all the values are 0, the value allocated to MAX TASKS may be more than you need. If the value is high, increase the MAX TASKS and MAX ERUS allocation, provided your system has enough resources available to support increased task activity.
