3 Understanding the Business Intelligence Enterprise Deployment Topology
The following topics describe the Oracle Business Intelligence enterprise deployment topologies.
These topologies represent specific reference implementations of the concepts described in About a Typical Enterprise Deployment.

Understanding the Primary Business Intelligence Topology Diagram
This section provides information about the elements that are unique to the primary topology.
Most of the elements of Oracle Business Intelligence topologies represent standard features of any enterprise topology that follows the Oracle-recommended best practices. These elements are described in detail in About a Typical Enterprise Deployment.
Before you review the information here, it is assumed you have reviewed the information in About a Typical Enterprise Deployment and that you are familiar with the general concepts of an enterprise deployment topology.
See the following sections for information about the elements that are unique to the topology described in this chapter.
Summary of Business Intelligence Load Balancer Virtual Server Names
In order to balance the load on servers and to provide high availability, the hardware load balancer is configured to recognize a set of virtual server names.
For information about the purpose of each of these server names, see Summary of the Typical Load Balancer Virtual Server Names.
The following virtual server names are recognized by the hardware load balancer in Oracle Business Intelligence topologies:
-
bi.example.com- This virtual server name is used for all incoming traffic. It acts as the access point for all HTTP traffic to the runtime Business Intelligence components. The load balancer routes all requests to this virtual server name over SSL. As a result, clients access this service using the following secure address:bi.example.com:443
-
biinternal.example.com- This virtual server name is for internal communications between the application tier components only and is not exposed to the Internet.The traffic from clients to this URL is not SSL-enabled. Clients access this service using the following address and the requests are forwarded to port 7777 on WEBHOST1 and WEBHOST2:
biinternal.example.com:80
-
admin.example.com- This virtual server name is for administrators who need to access the Oracle Enterprise Manager Fusion Middleware Control and Oracle WebLogic Server Administration Console interfaces.
Use instructions later in this guide to perform the following tasks:
-
Configure the hardware load balancer to recognize and route requests to the virtual host names
-
Configure the Oracle HTTP Server instances on the Web Tier to recognize and properly route requests to these virtual host names to the correct host computers.
Summary of the Managed Servers and Cluster on the Business Intelligence Application Tier
The Application tier hosts the Administration Server and Managed Servers in the Oracle WebLogic Server domain.
Depending upon the topology you select, the Oracle WebLogic Server domain for the domain consists of the cluster shown in Table 3-1. This cluster functions as activeactive high availability configurations.

Flow Charts and Roadmaps for Implementing the Primary Business Intelligence Enterprise Topologies
This section summarizes the high-level steps you must perform to install and configure the enterprise topology described in this chapter.
Flow Chart of the Steps to Install and Configure the Primary Business Intelligence Enterprise Topologies
Table 3-1 shows a flow chart of the steps required to install and configure the primary enterprise deployment topologies described in this chapter. The sections following the flow chart explain each step in the flow chart.
This guide is designed so you can start with a working Business Intelligence domain and then later scale out the domain to add additional capabilities.
This modular approach to building the topology allows you to make strategic decisions, based on your hardware and software resources, as well as the Oracle Business Intelligence features that are most important to your organization.
It also allows you to validate and troubleshoot each individual product or component as they are configured.
This does not imply that configuring multiple products in one Configuration Wizard session is not supported; it is possible to group various extensions like the ones presented in this guide in one Configuration Wizard execution. However, the instructions in this guide focus primarily on the modular approach to building an enterprise deployment.
