Key Features: Key Features Oracle Business Intelligence is now more integrated with the Oracle Fusion Middleware Oracle WebLogic Server replaces Oracle Application Server and Oracle Containers for Java (OC4J) Oracle Business Intelligence 11g Installer replaces the installer that was used in previous versions Key Features..continued: Key Features ..continued Following administration command-line utilities available Oracle WebLogic Server scripting tool (WLST) for managing the Oracle WebLogic Server domain OPMN and the opmnctl commands for the Oracle Process Manager and Notification Server A database repository must be created before installation of the components with the Repository Creation Utility (RCU) tool Enhancements to the Oracle BI repository Log centralization via the web log viewer OBIEE is now deployed in a clustered configuration by default. Because of this, the default ODBC DSN for the Oracle BI Server points to the Cluster Controller by default, rather than to the Oracle BI Server. Basic Architecture: Basic Architecture System and Java Components: OBIEE Components divided into System and Java Components. System components are still C/C++ executable and are controlled by OPMN and managed by Fusion Middleware Control Java Components are J2EE applications and are usually installed in the managed server and controlled by Fusion Middleware Control. System and Java Components Oracle Process Manger and Notification Server: OPMN ( Oracle Process Manager and Notification Server ) You may have first come across this in Oracle Application Server 10g, where it was used to start up the various Application Server components (OC4J_BI_Forms, OC4J_Portal etc ). Its since been adopted across the technology stack to start, stop and monitor processes across distributed servers, and it’s used in OBIEE 11g to do the same for the system components (BI Server, BI Presentation Server, BI Scheduler and BI Cluster Controller). You can either access OPMN through the command line ( opmnctl ), or Oracle’s recommended approach is to use a graphical interface within Fusion Middleware Control. OPMN is also used in the 11g stack to control Essbase, Discoverer and other BI components, so it’s a tool that’s worth learning Oracle Process Manger and Notification Server Oracle Enterprise Manager Fusion Middleware Control: Manage System Components (BI Server, BI Presentation Server etc) Start, Stop and Restart all System Components and Managed Servers Configure Preferences and Defaults Scale out System Components Performance Monitoring and Diagnostics Oracle Enterprise Manager Fusion Middleware Control WebLogic Domain: Each OBIEE 11g Oracle BI Domain contains a single Weblogic Domain. Contains one Admin Server and at the Start, One Managed Server WebLogic Domain administered through Admin Console and WLST(WebLogic Scripting). Managed Servers can be started manually or through Node Manager. WebLogic Domain Oracle Instances: Oracle Instances Collection of system components on a single host. Managed using OPMN. Starts with one of each system component. An Oracle BI Domain can contain multiple instances, one per host. 11g vs 10g: OBIEE11g has had a major architectural overhaul adopting Fusion Middleware 11g technologies Core servers stay the same, but new middleware “wrapper”. Main difference is wrapping components in WLS platform and EM management Uses WebLogic Application Server for J2EE application hosting, security and integration Major security enhancements and changes Enterprise Manager used for systems 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 11g vs 10g 11g vs 10g..continued: 11g vs 10g ..continued Users queries via the Presentation Server The Oracle BI Server converts these queries to physical SQL/MDX, via the Oracle BI Repository Queries are passed to the underlying physical databases and OLAP cubes Data returned to users in the form of dashboards and reports OBIEE 11g still works in fundamentally the same way as OBIEE 10g.
