OBIEE 11g Architecture

OBIEE 11g Architecture

At this high level, components in OBIEE 11g can be divided into two types:

• Java Components, the parts of OBIEE that are written in J2EE and run directly in the application server. These components include BI Publisher, the BI Office plugin, the BI Security Service, BI SOA Services, BI Action Services and the JMX MBeans that are used for configuring OBIEE

• System Components, which were implemented as Windows services in 10g, and include the BI Server, BI Presentation Server, BI Scheduler and BI Cluster Controller

Web Logic Server

This part of OBIEE system contains Admin Server and Managed Server. Admin server is responsible for managing the start and stop processes for Managed server. Managed Server comprises of BI Plugin, Security, Publisher, SOA, BI Office, etc.

Node Manager

Node Manager triggers the auto start, stop, restart activities and provides process management activities for Admin and Managed server.

Oracle Process Manager and Notification Server (OPMN)

OPMN is used to start and stop all components of BI system. It is managed and controlled by Fusion Middleware Controller.

Oracle BI System Components

These are non-Java components in an OBIEE system.

Oracle BI Server

This is the heart of Oracle BI system and is responsible for providing data and query access capabilities.

BI Presentation Server

It is responsible to present data from BI server to web clients which is requested by the end users.

Scheduler

This component provides scheduling capability in BI system and it has its own scheduler to schedule jobs in OBIEE system.

Oracle BI Java Host

This is responsible for enabling BI Presentation server to support various Java tasks for BI Scheduler, Publisher and graphs.

BI Cluster Controller

This is used for load balancing purposes to ensure that the load is evenly assigned to all BI server processes.
