What Is the System Logical Architecture?
The Oracle Business Intelligence system logical architecture comprises a single integrated set of manageable components called the Oracle BI domain which can be installed and configured to work together on a single host or can be clustered across multiple hosts for performance and availability.
Note:
You can improve the performance of your production system by using a web server with Oracle Business Intelligence, such as Oracle HTTP Server or Apache HTTP Server. A web server is not included by default in the Oracle Business Intelligence installer and is not part of the Oracle Business Intelligence system logical architecture. You must install and configure a web server separately.This section contains the following topics:
Oracle Business Intelligence System Architecture
You install Oracle Business Intelligence on a single host, but can subsequently scale out onto additional computers.
For more information, see Scaling Your Deployment.
The figure below illustrates the Oracle Business Intelligence system architecture on a single host. For more information, see Oracle Business Intelligence Components.
Oracle Business Intelligence is installed on a single host but can be scaled out onto multiple hosts. Java components (WebLogic server domain) and system components are clustered on each host as part of the single BI domain. The Administration Server exists on both hosts, but will be active on only one host.
Oracle Business Intelligence Components
When you install Oracle Business Intelligence, you can install several components in the Oracle BI Domain on the host.
The BI Domain consists of Java components that are deployed into one or more Java EE (JEE) containers within a single WebLogic server domain; system (non-JEE) components and processes; and required configuration files, metadata repositories, and infrastructure.
-
Admin Server — Deployed as a JEE container that runs in a dedicated Java virtual machine that contains Java components for administering the system. These components include Oracle WebLogic Server Administration Console, Oracle Fusion Middleware Control, and JMX MBeans.
-
Managed Server — Deployed as a JEE container that runs in a dedicated Java virtual machine that provides the runtime environment for the Java-based services and applications within the system. These services and applications include Oracle BI Publisher, Visual Analyzer, Presentation Services, and Composer.
An Oracle BI domain contains one or more Managed Servers that are distributed across one or more host computers.
-
Node Manager — Provides process management services for the Administration Server, Managed Server processes, and System Components.
For more information, see Node Manager Overview in Administering Node Manager for Oracle WebLogic Server.
-
System Components — Deployed as server processes and provide the core services that enable Oracle Business Intelligence.
For more information, see About the Administration Server, Managed Servers, and System Components. For information about controlling system processes, see Process Control Commands.
-
Other Domain Contents — Includes all the necessary software, configuration files, metadata, WLST commands, security, and connection and database configuration information that are required to run an Oracle Business Intelligence system.
For more information about:
-
Security configuration - See Security Guide for Oracle Business Intelligence Enterprise Edition.
-
Metadata - See Managing Metadata and Working with Service Instances and Metadata Repository Builder's Guide for Oracle Business Intelligence Enterprise Edition.

About the Administration Server, Managed Servers, and System Components
Oracle Business Intelligence contains an Administration server, Managed servers, and system components which are described in this section.
For more information, see Getting Started Managing Oracle Fusion Middleware in Administering Oracle Fusion Middleware.
For information about Essbase when installed with Oracle Business Intelligence, see What System Administration Tools Manage Oracle Business Intelligence?.
About the Administration Server and Managed Servers
The Administration server and Managed servers are Java components deployed as one or more Java EE applications and described in the following list:
-
Administration Server — Manages configuration and runtime settings for Oracle Business Intelligence for a single or multi-node (distributed) BI domain, using:
-
Fusion Middleware Control — An administrative user interface that is used to manage the BI domain.
-
WebLogic Server Administration Console — An administrative user interface that provides advanced management for WebLogic, JEE components, and security.
For more information, see What System Administration Tools Manage Oracle Business Intelligence?.
-
-
Managed Server — Manages the following components:
-
Action Service — This component provides the dedicated web services that are required by the Action Framework and that enable an administrator to manually configure which web service directories can be browsed by users when they create actions.
-
Visual Analyzer — This component provides a simple-to-use visual analytical interface.
-
BI Publisher — This component provides an enterprise reporting solution for authoring, managing, and delivering all types of highly formatted documents to employees, customers, and suppliers.
-
Security — This component provides dedicated web services that enable the integration of the Oracle BI Server with the Oracle Fusion Middleware security platform.
-
SOA Web Service — This component provides dedicated web services for objects in the Oracle BI Presentation Catalog, to invoke analyses, agents, and conditions. These services make it easy to invoke Oracle Business Intelligence functionality from Business Process Execution Language (BPEL) processes.
-
Presentation Services — This component is a JEE application that routes HTTP and SOAP requests to Oracle BI Presentation Services.
-
About System Components
System components are deployed as non-JEE components, such as processes and services written in C++ and J2SE, and are described in the following list:
-
BI Server (OBIS) — This component provides the query and data access capabilities at the heart of Oracle Business Intelligence and provides services for accessing and managing the enterprise semantic model (stored in a file with an .RPD extension).
-
BI Scheduler (OBISCH) — This component provides extensible scheduling for analyses to be delivered to users at specified times. (Oracle BI Publisher has its own scheduler.)
-
BI JavaHost (OBIJH) — This component provides component services that enable Oracle BI Presentation Services to support various components such as Java tasks for Oracle BI Scheduler, Oracle BI Publisher, and graph generation. It also enables Oracle BI Server query access to Hyperion Financial Management and Hyperion Planning data sources.
-
BI Presentation Server (OBIPS) — This component provides the framework and interface for the presentation of business intelligence data to web clients. It maintains an Oracle BI Presentation Catalog service on the file system for the customization of this presentation framework.
-
Cluster Controller (OBICCS) — This component distributes requests to the BI Server, ensuring requests are evenly load-balanced across all BI Server process instances in the BI domain.
