Using DB Historical Data Analyzer in the TSO/ISPF environment

In the TSO/ISPF environment, DB Historical Data Analyzer provides a function to create charts to show the historical trend of various aspects of IMS full-function database data set groups.

The statistical data to be shown on the charts is obtained from the HISTORY data set produced by HD Pointer Checker and the Space Monitor graph record data set produced by Space Monitor.

The charts are displayed on your TSO terminal as the result of a dialog with DB Historical Data Analyzer and ICU through panels. The hard copies of the charts can also be obtained on printers that GDDM supports using GDDM provided printing utilities.

By using the ICU standard functions, you can generate any of the nine types of chart: line graph, surface chart, histogram, bar chart, pie chart, venn diagram, polar chart, tower chart, and table chart. The charts show database analysis information about the following major subjects:

• Database blocks
• Database free space
• Database segments
• Database root segments
• Database root segments and dependent segments
• Database records
• Space allocation
