In some cases, running reports can impact performance because of high demands on
database processing. To reduce the performance impact of running reports, you can specify that
some reports obtain data from a separate reports database, which can be a copy of all or part of
the PegaRULES database.
The reports database must have the same structure (tables and columns) as the PegaRULES
database. A reports database might contain only a subset of the tables needed for reporting,
and might contain old
data.
-
Work with a database administrator to create the reports database, identifying the
tables, indexes, and views to include.
-
Work with a database administrator to set up database replication, which uses a
mirroring technique.
-
Create a database data instance ( Data-Admin-DB-Name ) for the
reports database and establish connectivity. For more information, see Creating database data instances.
-
Update the Database Table data instances to identify this database on the
Database tab in the Reports Database
field.
-
In the report definition rule that obtains data from the reports database, on the
Data Access tab, select the Prefer reporting data
source if defined option in the Reporting database
field.
Note: To require the use of a reports database for standard list view and summary view
reports when the Prefer reporting data source if defined option
is not selected, set the pyUseAlternateDb parameter to
true when calling the Rule-Obj-ListView.ShowView
or Rule-Obj-SummaryView.ShowView activities.
