2

• Overview of OBIEE 11gR1
• Key Features
• Basic Architecture
• System and Java Components
• Oracle Process Manager and Notification Server
• Oracle Enterprise Manager Fusion Middleware
  Control
• Weblogic Domain
• Oracle instances
• 11g vs 10g
• Q A

3

• Derived from Siebel Analytics, second major
  Oracle release.
• 11gR1 new features focused on manageability and
  Middleware integration.

4

• 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

5

• 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.

• 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.

8

• 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 its 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 Oracles 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
  its a tool thats worth learning

9

• 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

10

• Each OBIEE 11g Oracle BI Domain contains a
  single Weblogic Domain.
• Contains one Admin Server and at the Start, One
  ManagedServer
• WebLogic Domain administered through Admin
  Console and WLST(WebLogic Scripting).
• Managed Servers can be started manually or
  through Node Manager.

11

• 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.

12

• 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

13
OBIEE 11g still works in fundamentally the same
way as OBIEE 10g.

• 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
