Oracle SOA Suite EDN provides the following features:

• A standard JMS-based messaging infrastructure that provides the following:

  • A JMS-based event publish and subscribe architecture for Oracle SOA Suite and non-Oracle SOA Suite clients.

  • Support for bidirectional interactions (can both publish to and subscribe from Oracle SOA Suite and non-Oracle SOA Suite clients).

  • Support for both the Oracle AQ JMS and Oracle WebLogic Server JMS providers. An Oracle WebLogic Server JMS topic (default) and an AQ JMS topic are automatically configured for EDN use after installation. The default JMS type can be switched from Oracle WebLogic Server JMS (default) to AQ JMS in Oracle Enterprise Manager Fusion Middleware Control. For more information, see "Mapping Business Events to JMS Topic Destinations on the Business Events Page" of Administering Oracle SOA Suite and Oracle Business Process Management Suite.

  • EDN support as a lightweight manager above both JMS providers.

  • A plain JMS API and an Oracle SOA Suite, value-added EDN API for remote, non-Oracle SOA Suite clients to use for integrating with Oracle SOA Suite. For more information, see Java API Reference for Oracle SOA Suite Event Delivery Network.

  • JMS transactions to guarantee EDN delivery (for both the one-and-only-one (OAOO) and guaranteed consistency methods).

  • Durable and persistent publishing delivery options to prevent message loss. These default options are beneficial for interactions with remote, non-Oracle SOA Suite clients.

  • A JMS adapter used internally for implementing many JMS features. For information about the JMS adapter, see the "Oracle JCA Adapter for JMS" chapter of Understanding Technology Adapters.

  • No duplicate event processing in a multinode cluster.

• Scalability at a fine-grained level. This enables different events to map to different JMS topic destinations, thereby eliminating the need for a single location to handle all events. This reduces potential bottlenecks. Mapping is performed by an administrator in Oracle Enterprise Manager Fusion Middleware Control. For more information, see the "Mapping Business Events to JMS Topic Destinations" section of Administering Oracle SOA Suite and Oracle Business Process Management Suite.

• Support for the following publish and subscribe scenarios:

  • Publish and subscribe to events across the same composite or different composites.

    • Use the default EDN Oracle WebLogic Server JMS topic automatically provided.

    • Use the custom event-to-JMS-topic mapping provided in Oracle Enterprise Manager Fusion Middleware Control.

  • Publish and subscribe to events with remote, non-Oracle SOA Suite participants through one of the following APIs:

    • Plain JMS API (for J2SE client environments)

    • EDI API EdnJmsConnection (for J2SE and J2EE client environments)

• Instance tracking and fault recovery support in the Error Hospital. For more information, see Administering Oracle SOA Suite and Oracle Business Process Management Suite.

• The storage of EDL files in the MDS Repository. This makes the files available for browsing in the Resources window in Oracle JDeveloper. For more information, see Managing Shared Data with the Design-Time .
