Oracle SOA Suite 11g has an out-of-the-box Event Delivery Network (EDN) that allows you to publish and subscribe to business events. The EDN framework creates the messaging plumbing out of the box, that is, you will not have to create any backend queues to support event delivery and consumption in the infrastructure. The default EDN is configured on the database, and this uses Oracle Advanced Queuing (AQ) behind the scenes. You can also have EDN based on JMS that uses the JMS API. In the development and testing stage, access to the EDN logs is of great help to identify and troubleshoot issues with your EDN implementation. EDN logging level can be changed by following the next steps:
1. Log in to Oracle Manager Fusion Middleware Control.
2. Right-click on soa-infra, then navigate to Logs | Log Configuration.
3. Expand the logger nodes to oracle.integration.platform.blocks.event or enter
blocks.eventin the search box and click on the Search button...
