If you are going to install the Rules Engine, create the BusinessRules database component. As each Rules Engine instance starts, it registers itself in this database component and stores information about deployed projects and the state of business rules instances. When you modify a business rule, the hot deployment functionality in the Business Rules user interface enables you to deploy changes to all of the instances registered in this database component. If you install multiple Rules Engine instances, create a single BusinessRules database component for the instances to share. You must create the database component in the same schema (Oracle) or database (DB2, MySQL, or SQL Server) as the ProcessAudit database component.
