Fault Management in Oracle Service Bus

On September 26, 2011   /   Lesson05-Exceptions, OSB   /   3 Comments

I received queries from some of the readers on ’s fault handling behaviour recently. I thought best way to explain would be through an example and here we go …

Above example, deals with two look up services: Airport and Currency. These would be installed in BPEL as SOAP services. Oracle Service Bus will then invoke these services with the help of appropriate business services and a common . If either currency or airport code is not found, BPEL webservices will throw InvalidCurrencyFault and InvalidAirportFault respectively. These Faults are captured at OSB’s proxy stage with the help of Error Handler defined at “Route Node” stage. OSB then transforms these faults into appropriate common faults and sends response back to the client. For more details on Routing and Transformation in OSB, please refer to this example.

Introduction to Oracle Service Bus

On April 13, 2011   /   Lesson01-Oracle Service Bus   /   2 Comments

Oracle Service Bus (previously known as Weblogic ALSB) is a light weight messaging component of SOA Suite. In addition to providing basic routing and transformation services, also provides advanced capabilities for service abstraction.

As of version 11.1.1.3, OSB can only run on Weblogic platform. Since it runs in a separate JVM, there is an overhead in communicating with rest of SOA Suite components.

Though OSB is similar to Mediator component at the conceptual level, there are specific scenarios when OSB will be very useful.
