Oracle^® Business Intelligence Enterprise Edition Deployment Guide > Deploying Oracle Business Intelligence for High Availability >

Planning For the Installation

This topic provides general guidelines to help you plan the installation of Oracle BI for high availability.

Review the Systems Requirements and Supported Platforms Guide for Oracle Business Intelligence Suite Enterprise Edition 10.1.3.2. Also review the Oracle Business Intelligence Infrastructure Installation and Configuration Guide for information on installation requirements.

Determine the number of instances of each Oracle BI component that will form part of the deployment based on your requirements. The maximum number of BI Servers that can participate in a cluster is 16. BI Scheduler instances participate in the cluster in an active-passive configuration. Only one BI Scheduler instance is active and processing requests at a given time; the other instances are passive.

NOTE:  For purposes of illustrations, this document describes the installation of two instances of each Oracle BI component.

Determine which BI components will be co-located. For example, the Primary Cluster Controller, one BI Server node and BI Scheduler may be installed on one machine.

NOTE:  For the purposes of illustration, this topic describes the installation of Oracle BI components on separate machines.

Identify the machines on which you will deploy the Oracle BI components. Refer to the Systems Requirements and Supported Platforms Guide for Oracle Business Intelligence Suite Enterprise Edition 10.1.3.2 for more information on supported operating systems and hardware requirements.

Identify a shared network location for the Presentation Catalog, Repository Publishing Directory, Cluster-Aware Cache and Scheduler Scripts.

Refer to the Systems Requirements and Supported Platforms Guide for Oracle Business Intelligence Suite Enterprise Edition 10.1.3.2 and to the topic Shared Files and Directories for requirements and considerations for the shared file systems.

For deployments on Windows, identify a Domain account under which the BI services will run. This Domain account must also have the Log on as a service right. Refer to the appendix Granting the Oracle BI Log On as Service Right for procedures to perform the task of granting the Log on as a service right based on your specific Windows platform.

Note the following requirements:

• All BI Servers participating in the cluster need to be within the same domain and on the same LAN subnet. Geographically separated computers are not supported.
• The clock on each server participating in a cluster must be kept in synchronization. Out-of-sync clocks can skew reporting.
