User Created AVGPERF Delta Rowset

In addition to the system created Delta rowsets created by the DELTACRE function, you can create additional Delta rowsets based on the combination of existing Delta rowsets into a new rowset known as a DELTA AVGPERF rowset. Keywords are provided to allow you to select the Delta rowsets that will be included for summarization. During the AVGPERF function, special data handling is performed according to the following:

• Beginning date and time information is taken from the earliest rowset processed
• Ending date and time information is taken from the oldest rowset processed
• The duration column is set to 1.0 (1 hour)
• Counter columns are added together (summarized) and then divided by the total of all duration hours from the input rowsets
• Non-counter columns are set to the value of the oldest (ending) rowset
