    • OBIEE 11g Single-Node Architecture • Overall stack is an Oracle BI Domain • Made up of three areas ‣ WLS Admin Server + FMW Control (EM) ‣ System Components ‣ WLS Managed Server with Java Components • Initial (11.1.1.3) version only supports WLS 11g (10.3) • Same fundamental components as 10g, but now integrated with FMW WLS stack T : +44 (0) 8446 697 995 or (888) 631 1410 (USA) E : enquiries@rittmanmead.com W: www.rittmanmead.comTuesday 12 April 2011
    • OBIEE 11g System Components, Java Components and OPMN • OBIEE components divided into System and Java components • System components are still C/C++ executables, are controlled by OPMN, and are managed by Fusion Middleware Control • Java Components are JEE applications, are installed in the managed server, and are controlled by FMW Control T : +44 (0) 8446 697 995 or (888) 631 1410 (USA) E : enquiries@rittmanmead.com W: www.rittmanmead.comTuesday 12 April 2011
    • Administration and Management • WLS Admin Server used for controlling WLS platform ‣ Startup, shutdown, security, non-OBIEE specific tasks • Fusion Middleware Control (EM) used for managing OBIEE • OPMN used for starting, stopping system components • Node Manager used for starting, stopping managed servers T : +44 (0) 8446 697 995 or (888) 631 1410 (USA) E : enquiries@rittmanmead.com W: www.rittmanmead.comTuesday 12 April 2011
    • 11g Architecture Compared to 10g Architecture • Main difference is wrapping components in WLS platform and EM management • Individual servers, components are still the same (BI Server, Presentation Server, BI Publisher J2EE application etc) • Some reworking has taken place in 11gR1 (unified logging, management of config files using EM etc) • Basic concepts, plus clustering (OBIEE), scheduling etc are the same as in 10g Web Server SAW Bridge (J2EE/ISAPI) Web Browser (IIS, Tomcat, Websphere, iPlanet) XML, HTML, Javascript XLS, PDF, TXT for Usability & Interactivity Oracle BI Publisher Oracle BI Presentation Services TCP/IP (SSL) over HTTP/HTTPS Delivery Server SOAP Web Services, XML and URL Interface Web Catalog Layout Interfaces Service Oracle Interactive Oracle Answers Dashboards Data Logic HTML, SOAP XSL XML User Profiling, Security and Session Mngmt over Framework HTTP/HTTPS Cache Services (Web) & Connection Mngmt External Applications and Portals ODBC over TCP/IP (SSL) Oracle Delivers Server Oracle BI Server TCP/IP Scheduling/Event Services (SSL) Logical SQL ODBC/JDBC (Logical Business Model) vs Agent Execution Logic Load Balancer Metadata Interchange Device Adaptive Content Session Management Intelligent Request Generation Oracle BI Administration .
