6 Oracle Enterprise Service Bus: Objectives No Coding Required Put proprietary technologies at the edges of SOA Abstract IT resources as services Achieve Separation of Concerns Between IT and Business

7 How IT events can negatively impact business processes Loan approval process jdbc:oracle:thin: saturn:1521:orcl Host: Port:2320 DB SAP Loan approval process jdbc:oracle:thin: mars:1521:orcl Host: Port:2320 Database moves DB SAP BPM BPM Business process needs revision!

8 Achieving Separation of Concerns Database moves Loan approval process BPM CreateCustomer.wsdl ESB jdbc:oracle:thin: saturn:1521:orcl Host: Port:2320 DB SAP Loan approval process BPM CreateCustomer.wsdl ESB jdbc:oracle:thin: mars :1521:orcl Host: Port:2320 jdbc:oracle:thin: jupiter:1523:audit DB SAP Audit DB Business process remains unchanged Audit DB added

9 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,

10 Virtualize Endpoints: Connecting to Target Systems 1. Web Services: PeopleSoft, Amazon, 2. Applications: e-business Suite, SAP, 3. Legacy: CICS, Tuxedo, 4. Technologies: database, file, JMS, Non-WS Connectivity through Adapters Standard JCA 1.5 Transactional (whenever possible) Sync, Async, bi-directional Wizards-driven, graphical introspection of target systems Adapters Bundled with ESB AQ, MQ, RDBMS, File, FTP, JMS, MQ, Oracle Applications and 300+ more available via OEM (iway, Attunity)!

11 Virtualize Endpoints: Web-service enablement of existing resources Host: , Port:2320 Service Consumer Native API [proprietary protocol] Native API CRM Service Consumer CreateCustomer.wsdl [SOAP] JCA Adapter Native API Host: Port:2320 [proprietary protocol] Native API CRM ESB Service consumers no longer need to talk proprietary protocols

12 Virtualize Endpoints: Introspecting Target Systems DB e-business Suite JMS

13 Transform Convert data as it flows through the bus Canonical or point-to-point transformations Standard XSLT for expressing transformations Drag-and-drop graphical mapping tool Smart mapping tool, dictionary-based Domain-Value Maps for fast, static, in-memory lookups

14 Route Reliably transport and route data over a variety of protocols Reliable messaging and guaranteed delivery are key in highly-distributed, asynchronous, fire-andforget SOA where senders do not wait for a response. Internally: uses JMS for asynchronous flows On the edges: wide support of transports SOAP, JMS, legacy messaging Hot-pluggable transport: 3rd Party JMS, DB, J2EE

15 Route: Taking Decisions Content-based: if total_price > 500, route to FedEx Header-based: if message_type = order, route to fulfillment Standard XPath to define routing expressions Graphical expression builder Routing rules can be altered at runtime

16 Expose Everything As A Web-Service By default, any ESB service is exposed as a web service (WSDL autogenerated) Each step of an ESB flow is a potential entry point Each web-service can be secured

17 Program <Insert Picture Here> The Oracle SOA Suite Enterprise Service Bus: Foundation for SOA ESB Usage Patterns Features & Characteristics Conclusion

18 Usage Patterns: simple synchronous request/reply flow Basic RPC mechanism requestor GetCustomer.wsdl

19 Usage Patterns: non-deterministic synchronous request/reply flow Consumer does not explicitly know the service provider Service provider selection based on message content/header requestor GetCustomer.wsdl

20 Usage Patterns: simple 1-way asynchronous flow The simplest but also the most typical ESB pattern Fire-and-forget event CreateCustomer.wsdl

21 Usage Patterns: fan-out 1-way asynchronous flow 1 event triggers multiple parallel operations All outbound operations can be grouped in one or more transactions 2 Customer details are logged in the audit database event CreateCustomer.wsdl 2 Customer details are enqueued on JMS to the CRM 1 An event is placed on the bus to notify of a new customer. Payload is customer details. 2 Customer details are enqueued on MQ to the mainframe

22 Usage Patterns: Response-forwarding Can be used for Routing based on lookup Asynchronous request/reply 2 Get customer address from database 1 event An event is placed on the bus to indicate an order is ready for shipment. Payload consists of order details and customer ID. ShipOrder.wsdl 3 Combine order details and customer details to prepare shipping

23 Usage Patterns: Canonical Data Model All messages on the bus are converted to a common data model Reduces the overall number of maps to generate Respective application owners only need to know about 2 data models: their own one + the canonical one. CRM ERP CRM ERP COMMON DATA MODEL (Customer Object) Billing Shipping Billing Shipping

30 Security Main security challenges in distributed environments Islands of security lead to security gaps No end-to-end visibility Developers are not necessarily security experts Modifying policies is extremely complex ESB leverages the Oracle SOA infrastructure for security J2EE Container (OC4J) at service level Oracle Web Services Manager to configure global policies No security hard-coded in endpoints Deployment options: gateway or agent modes ESB sets and propagates security headers (WS-Security)

31 ESB, part of a truly integrated suite 1. Installation Single installer J2EE to Human Workflow under 20mn Single deployment platform 2. Design-Time Single design environment 3. Runtime Single monitoring UI (web browser) with Single Sign-On Direct Java binding between co-located components End-to-end instance tracking
