ACTIVITY Report

The ACTIVITY Report summarizes run unit activity in the Archive Journal file. The activity summarized can span the entire file, or can be from selected time periods. The report can be used to monitor run unit activity on an ongoing basis, with special attention paid to peak periods.

The ACTIVITY Report provides statistics on such items as:

• Number of run units initiated (START)
• Number of recovery checkpoints issued (COMMIT)
• Number of units successfully terminated (FINISH)
• Number of recovery units which terminated abnormally (ABORT)
• Number of run units active within the reported time interval (ACTIVE)
• Duration of run units within the reported time interval (DURATION)

The activity statistics are reported in the time intervals you specify (for example hourly). For each time interval, activity is divided into online (ONL) and batch (BTC) run units, and reported accordingly. If both ONL and BTC run units are reported, a total (TOT) summary line is also produced. A set of GRAND TOTALS summarize all activity within the reporting periods.

By examining the reported totals such as the Maximum Concurrent Run Unit Count, the adequacy of the CV generation parameters can be evaluated. In addition, the ACTIVITY Report can help to verify your suspicions of undue or unusual system activity. This may lead you to the use of other Journal Reports or Journal Displays for the time intervals in question.

Note: It is recommended that the ACTIVITY Report be generated on a daily basis in order to get an overall view of system activity.
