While working with the existing installation of Business Process Server, you can choose to use another database and point Business Process Server setup to it. You can configure the new database with Business Process Server using the Database Configuration Tool. This is a special Business Process Server Tool and can be accessed from the Start menu. The Database Configuration Tool changes the database-related properties in all Business Process Server *.conf and *.properties files, and uses appserver MBeans to delete and recreate the appserver data sources with the new properties.
