What is an HDB?
An HDB (Historical Database) is a definition that allows you to collect, report and manage CICSĀ® statistics and transaction performance data. In CICS PA you can create as many HDBs as required.
An HDB has the following components:
- Options that allow you to tailor the HDB to meet your requirements.
- A Template that defines the CICS performance data to be included in the HDB. Templates allow you to customize what information is to be contained in the HDB. They are similar to Report Forms. Templates are relevant only to List and Summary Performance HDBs. They are not required for Statistics HDBs.
- Selection Criteria that allow you to filter the CMF Performance Class data used to build the HDB.
- Container data sets that contain either HDB performance data, HDB statistics data, or HDB performance alert data.
There are two types of Performance HDB, List and Summary, where the HDB type is determined by the Template. There is a third type of HDB for CICS Statistics and Server statistics data and CICS Transaction Gateway statistics data. For a Statistics HDB, instead of a Template, you select from a menu the statistics categories and reports that identify the data that you want collected.
