Oracle Enterprise Service Bus: The Foundation for SOA ESB is a multi-protocol fabric to separate integration concerns from applications and business logic How is this achieved? 1. Virtualize Endpoints: From resources to services 2. Transform: Convert data to target formats 3. Route: Reliably transport and route data over a variety of protocols
Expose everything as web services 1.
Standards-based: XPath, XSLT, SOAP, JMS, JCA, …
2.
Hot-pluggable: J2EE, JMS, Database, …
Recent Customer Examples • Residential Mortgage Processing Company • ESB used as a reliable platform to connect clients and trading partners
• Specialty Insurance Company • Application Modernization Through SOA
• Top Government Agency • ESB as the backbone of the Police, Courts and Correctional Services Departments
• US State Division of Criminal and Juvenile Justice Planning • ESB for Criminal Justice Information System
Joan Lawson Director of Integration, Monster Worldwide, Inc. “Oracle’s SOA Suite gives us a complete set of service infrastructure components for building, deploying and managing SOAs. We can easily extend and evolve our architectures instead of replacing existing investments.”

Why Oracle Fusion Middleware? We evaluated several integration solutions, ranging from integration appliances to the Oracle SOA Suite. Oracle’s SOA Suite provided flexibility and rapid interface development capabilities. As an Oracle shop, we wanted to leverage our solid business relationship with a trusted vendor partner. After evaluating the different integration packages from Oracle, Microsoft, Cast Iron Systems, and IBM -- we felt Oracle SOA Suite was the best fit for our company.

Solution Highlights – Components for Success Oracle E-Business Suite (specifically the Projects module) Oracle BPEL Process Manager 10.1.3.3 Oracle ESB 10.1.3.3 Oracle Application Server 10.1.3.3 Oracle Applications Adapter for SOA Suite 10.1.3.3 F5 Load Balancer for high availability e2e Consulting - Worked with our internal team to gather requirements and build a best practices framework using BPEL Process Manager, Oracle ESB, and the Oracle Applications Adapter for Oracle EBusiness Suite. The Work Order integration process was architected to get maximum reuse of each independent service within the overall process.

The ESB and ESP…
Developing a canonical model allows multiple work order related services to push data into the ESB with a single publish service to the E-Business Suite
Discovering that a PL/SQL package can call a web service allowed us to change a polling process to a data push into the ESB
Coming to the understanding that old point-to-point interfaces can become a series of individual data publication services with multiple receivers (i.e. phone number change, name change, address change) makes the ESB a very powerful tool.

Benefits/ROI Short-term benefits:
Replace scheduled point-to-point integrations with a real-time SOA implementation Increase visibility to process performance and exceptions Reduce interface complexity Reduce time required to troubleshoot issues Improve error tracking and monitoring
Long-term benefits:
Create a framework of reusable components that will allow easy integration for additional work management applications Reduce interface complexity which makes interfaces easier to maintain Reduce the number of application interfaces Establish common services location for interface business logic Improve data quality
ROI:
Estimated 36% savings for new interface development time utilizing SOA Suite Estimated 50% savings for support and maintenance time Increased resource availability by having a single integration technology that lowers time to market development costs Reduced time to troubleshoot integration issues Reduced maintenance

Lessons Learned…
Having a cross-sectional IS group to review and select Fusion as our data integration tool brought visibility and consensus to the project
Having a partnership with e2e Consulting was instrumental to our success as they guided us through the initial product install and orchestration development
Taking the time to develop standards, best practices, and interface assessment templates was a prerequisite to our future build out of Fusion
Developing the canonical model for the interface early in the process helped drive the design
Designing the interface using a "Destination-to-Source" order helped ensure nothing was left out of the process
UniSource Energy Corporation Proprietary
12
Future Plans…
Any new application interfaces will be developed using Oracle Fusion Integration Architecture
Any existing interfaces that are associated with an application refresh project (maintain, upgrade, replace, retire) will be evaluated on a case-by-case basis for migration to the Oracle Fusion Integration Architecture
Leverage web services and XML components of packaged applications wherever and whenever possible
Ensure that each application development group (Business Applications, Customer Applications, and Operations Applications) and technical group have at least two developers/architects formally trained in the Oracle Fusion Integration Architecture
Leverage BPEL as a tool to engineer and re-engineer business processes

Advantages of The Integration Approach
Distribute information to all parts of your business easily and rapidly Hide differences in platform, software architecture and network protocols Assure delivery of information, even when systems and networks go off-line Reroute, log and enrich information, under central control, without rewriting applications Deploy solutions incrementally, project by project, to better manage expense Supports Message, Service and Event Oriented Architecture Improve system security, scalability, availability and robustness
Lessons Learned
Spend enough time in planning and laying out architecture and methodology before build Understand the hardware requirements clearly Rigor in methodology Canonical Data Models Service Contracts
Provide time in the schedule for stress testing Engage with Oracle !!!
