OSB Solves Brittle Integration Costs

OSB reduces complexity and increases visibility and re-use

Time to Market OSB insulates business logic from overhead

Scalability Proven to handle all dimensions of scalability

Multi-channel Delivery Separates service functionality from presentation layers

Risk Allows cached cloud service results to ensure high availability

and retain control

Value PropositionOracle Service Bus

Oracle Service Busdelivers business agility, scalability, and

performance into the business infrastructure toallow businesses to rapidly respond to new

business requests

Unlike traditional ESBsOracle Service Bus provides predictable scalability

for reducing risk, automated service pooling for highavailability, and service virtualization for agility

delivered within a single solution for a lower totalcost of ownership

Embrace & Extend Strategy Reassure customer they dont have to re-invent the wheel

E.g. Retain existing services and existing ESB

OSB will make all existing services (even tightly coupledones) and enforce loose coupling to introduce agility to

their existing architecture Ease of Use

Fit-to-Purpose interfaces - Available in a Web-basedconsole and deeper-dive IDE

Any-to-Any Protocol Support Regardless of new business request, OSB is pre-configured to handle the format

The goal: Give customers the ability to extend the set of standard

functions used in XQuery expressions and XQuery/XSLT resourceswith their own implementations, written in Java. The rationale: Certain transformations are too complicated or too

inefficient to be done with XQuery/XSLT language. For example,reuse utility complex transformation functions already existing in javaor even to do something with a database or some external system.

Feature Highlights Java Support

OSB enhanced to support Java Objects In the Pipeline, Java Object is represented as


41/53

43

Feature Highlights Java Support Message Format in the Pipeline

The invocation point is the top element Each argument is listed as a sub-element Primitives and string arguments are inlined POJO parameters referred by java-content ref.

XmlObject arguments can be inlined or passed as ref.

POJOs can only be modified in the pipeline through JavaCallout

44

Feature Highlights JEJB Inbound

Inbound EJB Transport exposes the Pipeline as a Stateless SessionBean Communication between the client and proxy service is an EJB

invocation Client defines the SLSB interface exposed by the JEJB Proxy

service EJB artifacts are generated on the fly at the time of proxy

creation Transaction and security context is propagated from the client into

the Bus
