How to use a reports database

Execution of V5 reports — summary view rules and list view rules — by application users or by agent processing may provide a substantial source of database processing database demand in some cases.

To reduce the performance impact of V5 report execution, you can direct that some reports obtain data from a separate reports database, which is a copy (a replicated mirror) of all or part of the live PegaRULES database.

The reports database must have the same structure (tables and columns ) of the live database, but may contain only a subset of the tables needed for reporting, and may contain slightly stale data.

To use a reports database:

Work with a database administrator to create the reports database, identifying the tables, indexes, and views that need to be included.
Work with a database administrator to set up the replication, which may use master-slave or other mirroring techniques.
Create a database data instance (Data-Admin-DB-Name) for the reports database and establish connectivity.
Update Database Table instances to identify this database in the Reports Database field.
Select the Use alternate database? option on the Content tab of list view or summary view rules that are to extract data from the reports database.

To disable use of a reports database even when the Use alternate database? option is set and the Reports Database field is not blank, add the following entry to your prconfig.xml file.

The default value is true.

As an alternative to the prconfig.xml file, you can use Dynamic System Settings to configure your application.
See How to create or update a prconfig setting.

Use of a reports database is less helpful in situations where JVM memory, CPU processing, or network traffic are more

To force the use of a reports database even for standard reports (for which the Use alternate database? option is not checked), set the pyUseAlternateDb parameter to true when calling the Rule-Obj-ListView.ShowView or Rule-Obj-SummaryView.ShowView activities.

Reports based on report definitions do not support the reports database feature; such reports always use data from the live PegaRULES database.
