Summary


History of the Oracle SOA platform

Oracle Service Bus

Oracle ESB

Oracle BPELSource: Oracle


Positioning products of Oracle SOA Suite 10g

BPEL Process Manager BPEL Process Manager is the primary composition, orchestration and process engine

in the SOA Suite

Oracle Enterprise Service Bus (OESB) old „ESB“ –OESB was the primary ESB prior to BEA aquisition. After acquisition of BEA its role is to provide mediation services between SOA Suite

components In 11g this will be known as the Mediator and acts as a component in an SCA assembly OESB is the only ESB available if running on a non-Weblogic server

Oracle Service Bus (OSB) Previously known as BEA Aqualogic Service Bus (ALSB) Oracle’s primary service bus the preferred platform for service virtualization and interactions external to the SOA

Suite Currently OSB is only available on WebLogic server but the intention is provide it on

other platforms as well in the future OSB is the foundation of service bus functionality moving forward Can be used independently, without SOA Suite

Summary


From Oracle SOA Suite 10g to 11g


What is new with Oracle SOA Suite 11g

Most importantly SOA Suite 11g sees the introduction of a common service infrastructure through the Service Component Architecture (SCA) Standard

This way the individual products of 10g become so called service engine within SCA With the benefit of a much better integration Mostly beneficial for the developer, as he can now develop and deploy from a single

development environment

The Oracle Service Bus (prev. BEA) is not yet available in a version 11g But version 3.1 can be combined with SOA Suite 11g with no problems

But when should we use which component?

How does a reasonable combination of Oracle SOA Suite 11g and Oracle Service Bus look like?

BPEL Primarily for stateful and long

services Integration of Rules Engine and

Human Workflow Instance Monitoring

OSB/Mediator Stateless Messaging Value Mapping and Cross-Reference

Tables for supporting canonical datamodels

Implementation of the VETRO pattern Validate Enrich Transform Route Operate


Mediator vs. Oracle Service Bus (OSB)

Mediator The “tiny”, “light weight” service bus Limited to simple Mediator functionality

for the implementation of the VETRO pattern Validate Enrich Transform Route Operate

Value Mapping and Cross-Reference Table for supporting the canonical datamodel

Developlent through JDeveloper IDE Event Delivery Network for Publish-

Subscribe semantic Message Transformation with XSLT Can be used and deployed as a SCA

component

Oracle Service Bus (OSB) The large, powerful service bus Extended functionality important for

enterprise-wide Integration, like Message Throttling Service Pooling Reliable Messaging

Development through Eclipse IDE or Web Console

Message Transformation over XQuery and XSLT

OSB specific deployment Not yet integrated with SCA


OSB: Service Pooling

If a URI is non-responsive, take the URI out of the poolBring the URI back in the pool when it is back-up

Routing to active endpoints, service load balancing Option for the system to automatically take non-responsive URIs out of the pool,

and put them back in as they become responsive

Alerts will be generated when the status of the endpoint changes from Up Down and vice versa


OSB: Split-Join

Incoming payload is split into multiple service invocations

Multiple service responses are aggregated into single payload

Parallel action results into significant performance improvement

Summary


Summary

Both Mediator 11g and Oracle Service Bus implements ESB functionally well

The decision which service bus to use, can be taken Based on the required and supported features Based on the information, if the SOA Suite 11g with all the other components

like BPEL, Rules, Human Workflow, etc. are needed as well or if only a standalone ESB is necessary

If other components of SOA Suite 11g are needed => Mediator more likely

If standalone ESB is needed => Oracle Service Bus more likely

In a large and complex SOA it makes sense to combine the two via the Federated Bus pattern i.e. using both the Mediator and Oracle Service Bus
