This chapter describes the deployment of Oracle Business Intelligence in a high availability environment. It outlines the installation and configuration procedures for the BI components needed to achieve end-to-end availability. The Oracle BI components are configured to use the native clustering, load balancing and failover mechanisms described in Clustering, Load Balancing, and Failover in Oracle Business Intelligence. BI components are deployed in either an active-active or active-passive mode to maximize availability.

Figure 4 shows the deployment of Oracle Business Intelligence for high availability.

• A Load Balancer serves as the entry point and load balances Oracle BI web requests to multiple web servers. Two scenarios for the web tier are shown.
  • The first scenario shows IIS as the web server with BI Presentation Services Plug-in (ISAPI) deployed.
  • The second scenario shows a J2EE based application server with BI Presentation Services Plug-in (Java Servlet) deployed in a web container in the J2EE server. For information on deploying the BI web tier in a De-Militarized Zone (DMZ) and details on communication over firewalls, see Other Deployment-Related Topics.
• Multiple instances of BI Presentation Services, BI Servers and BI Scheduler components are installed and the Oracle BI environment is configured for clustering, load balancing and failover of its components using native capability.
• Figure 4 does not show the lines of communication between the different BI components. See Figure 1 and the topic Communication Between Oracle BI Components in a Clustered Environment for details.

For details of the deployment of BI Publisher component for high availability, see the topic Deploying Oracle Business Intelligence Publisher for High Availability.
