OBIEE – Architecture
OBIEE Architecture involves various BI system components which are required to process the end user’s request.
How OBIEE System Actually Works?
The initial request from the end user is sent to the Presentation server. The Presentation server converts this request in logical SQL and forwards it to BI server component. BI server converts this into physical SQL and sends it to database to get the required result. This result is presented to the end user through the same way.
The following diagram shows detailed OBIEE Architecture −
OBIEE Architecture contains Java and non-Java components. Java components are Web Logic Server components and non-Java components are called Oracle BI system component.
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, Pubpsher, 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 capabipties.
BI Presentation Server
It is responsible to present data from BI server to web cpents which is requested by the end users.
Scheduler
This component provides schedupng capabipty in BI system and it has its own scheduler to schedule jobs in OBIEE system.
Oracle BI Java Host
This is responsible for enabpng BI Presentation server to support various Java tasks for BI Scheduler, Pubpsher 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.
