Administering and configuring Event Engine and Business Events

The Event Delivery Network (EDN) in Oracle SOA Suite 12c provides a declarative way to generate and consume business events that are managed by the event engine. When a business event is published, other service components or database agents can subscribe to it. The EDN-based event engine in Oracle SOA Suite 12c is a typical publisher-subscriber model that has two different implementations:

• AQJMS (Advanced Queuing) uses underlying database AQs as a backend store and depends on event delivery queue tables and stored procedures to manage events. The EDN AQs can be found under [PREFIX]_SOAINFRA schema with the EDN suffix.

• WLJMS (WebLogic) implementation uses backbone JMS queues. EDN-based event messages are published to and subscribed from EDNQueue (jms/fabric/EDNQueue) or EDNTopic (jms/fabric/EDNTopic) under Services | JMS Modules | SOAJMSModule in the WebLogic Server Administration Console.
