  1. Service Oriented Architecture Oracle SOA Suite 11g Master of Information System Management

  2. Oracle SOA Suite 11g (Advertisement) • SOA from a business point of view BAD = Business agility through decoupling! • Better integration with other enterprises • Become a customer-centered organization • Reduce costs Master of Information System Management

  3. Oracle SOA Suite 11g • SOA from an architectural point of view • Definition of "architecture": "The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution." ANSI/IEEE • Interoperable and loosely coupled service consumer, provider and registry • Support Governance and Event Driven Architecture Master of Information System Management

  4. Oracle SOA Suite 11g • SOA from an implementation point of view • Standards, Standards, Standards • Adherence to Policies Master of Information System Management

  5. Oracle Fusion Middleware and SOA Suite • Put together through acquisition of others (BEA, SUN, AmberPoint, PeopleSoft, and others). • These are intended to be best-of-bread acquisitions. • Based on Service Component Architecture (SCA 2007). • FMW 11g rolled out in July 2009. Master of Information System Management

  6. Oracle Fusion Middleware and SOA Suite • The coupling between service components is very loose - they do not need to know about each other. • Changes in location of services called, reliability requirements and security can be made without changing components. • Fusion middleware offers all middleware capabilities. • FMW 11g runs on WebLogic Server 11g • Fusion Middleware is not sold as a single product. • Different suites are offered: BPM Suite, EDA Suite, Governance Suite, SOA Suite Master of Information System Management

  7. SOA Suite 11g Key Components(1) • First and foremost an SCA container • Can run multiple instances of every composite application in parallel • Supports BPEL, Rules Engine Decision Service, Human workflow service, Spring based Java Beans, Mediator (transformation, routing, protocol adaption) and BPMN tools to generate BPEL Master of Information System Management

  8. SOA Suite 11g Key Components (2) • XML deployment descriptors are bundled together into archives: Java Archive (JAR), Service Assembly Archive (SAR), etc. • May be configured with Oracle Service Bus ESB. (BEA's AquaLogic Service Bus) • Provides BAM (Business Activity Monitoring - including real time data from security gates and RFID. Master of Information System Management

  9. SOA Suite 11g Key Components (3) • SOA Suite 11g runs inside WebLogic Server 11g. • Several web applications are included for configuring and monitoring FMW 11g runtime operations. • The most important is the The Oracle Enterprise Manager Fusion Middleware Control Console. • The main design time tool is JDeveloper 11g. • Many Design Time at Run Time features - DT@RT permits on the fly configurations. Master of Information System Management

  10. SOA Suite 11g Key Components (4) • Meta Data Services (MDS) manage XSD documents, mappings between different vocabularies in different domains, reusable transformations, human task definitions, security policies, business rule definitions, business event definitions, etc. • MDS provides a single interface across all repositories. • The Application Development Framework (ADF) is a Java Server Faces based framework for building rich Java web applications. It was used to create the Enterprise Manager. ADF Business Components are used to publish SDO services on top of the database. Master of Information System Management

  11. Getting Started • See Chapter 2 of “Oracle SOA Suite 11g R1 Developer’s Guide” • Build and deploy a simple BPEL process. • Include a Mediator in the same Service Composite. • Deploy a simple Proxy service and Business Service to the Oracle Service Bus. Master of Information System Management
