    Oracle service bus (osb) for the busy it Oracle service bus (osb) for the busy it Presentation Transcript

    • ORACLE Service Bus 11g For the Busy IT Professional DOAG2010 munz & more Dr. Frank Munz November 2010
    • INTRODCUTION getting started
    • Agenda 1.  Introduction 2.  Service Bus Positioning 3.  Core OSB Features, Development 4.  Monitoring, Security and Clustering (c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010) Slide #3
    • • Frank Munz • Research in supercomputing and medical imaging • Worked for and with TIBCO, BEA and Oracle • Founded munz & more in 2006 • Focus Oracle middleware … Who is this guy? Slide #4(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • munz & more http://www.munzanmdore.com
    • SERVICE ORIENTED service bus positioning
    • Interwoven silos with point to point integration The Enemy (c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010) Slide #7 Portal   RichClient   WebApp   Fraud   Billing   Network   CRM   web  service?  -­‐>  
    • General Questions Slide #8(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010) Where is your business logic ? What if you need to change it? How many systems require changes if one system changes? Do Web Services help? -> tight coupling L
    • Why not use e.g. EJBs then? Similar situation for EJBs: • Java only • Changes in interface require new stubs -> changes in client jar file Slide #9(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • Enterprise Application Integration (EAI) EAI tries to solve the integration problem Examples of EAI System are: • BEA Weblogic Integration (=WLI, discontinued) • TIBCO Business Works • Vitria • WebMethods Slide #10(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • EAI Characteristics • Addresses the integration problem -> Supports plenty of technical protocols • You need to DEPLOY the solution (EAR / JVM) • Does NOT support real business processes -> Technical level, NOT business level -> No long running processes (e.g. 10 years?) -> Not good in versioning Slide #11(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • EAI reduces complexity from O(n*n) to O(n): One change per system changed. Reduced Complexity (c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010) Slide #12 EAI  -­‐>OSB   Portal   RichClient   WebApp   Fraud   FTP   Billing   JMS   Network   EJB   CRM   JAXWS  
    • Business Process Management (BPM) BPM deals with business workflows Ideally: what you design is executable -> Visio templates do not qualify as BPM Examples of BPM Software: • Oracle BPM = Aqualogic BPM = Fuego • TIBCO IProcess & TIBCO InConcert Slide #13(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • BPM Characteristics • Business architect draws executable workflow that makes sense for business -> business logic • Human interaction • Long running processes (e.g. 2 yearly vehicle inspection stickers, TÜV) • Versioning of running processes Slide #14(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • Service Bus • Similar to EAI (same protocols) but configuration driven • Service Bus is stateless • Often replaces EAI: Weblogic Integration (=EAI) is obsolete now • You design message flows on a technical level Slide #15(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • Service Bus -> Service Virtualization Layer Slide #16(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • Drag and Drop Programming BPM, EAI and ESB: They all have executable, graphical flow diagrams. (c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010) Slide #17
    • Why OSB is not BPM nor EAI … not a BPM system: -> neither long running nor stateful nor versioning … more then an EAI system: -> configuration driven, registry / repository integration, SOA focused and better monitoring with SLAs. OSB typically does NOT host the services Slide #18(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • SOA Definition "Service-Oriented Architecture is an IT strategy that organizes the discrete functions contained in enterprise applications into interoperable, standards-based services that can be combined and reused quickly to meet business needs." Slide #19(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • What is SOA? SOA = BPM + ESB + X so what is X? Repository, Registry, Governance, … and what happened with EAI? often replaced by ESB Slide #20(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
    • ORACLE SERVICE BUS OVERVIEW basic features & architecture
    • Oracle Service Bus OSB 10gR3 • OSB was BEA Aqualogic Service Bus (ALSB) • ALSB based on code from Weblogic Integration (EAI) • Key product of the BEA acquisition • Integrates with UDDI V3 registry e.g. Oracle Enterprise Registry Slide #22(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)
