C Oracle Content DB In a High Availability Environment

This appendix explains where to find information about how to deploy Oracle Content DB in a high availability environment.

This appendix includes the following topics:

• Installation Order for High Availability Configurations

• High Availability for Oracle Database

• High Availability for Oracle Identity Management Components

• High Availability for the Oracle Content DB Middle Tier

C.1 Installation Order for High Availability Configurations

For all high availability configurations, install the components in the following order:

1. Oracle Database 10g

2. Oracle Identity Management components

   If you are distributing the Oracle Identity Management components, install them in the following order:

   1. Oracle Internet Directory and Oracle Directory Integration and Provisioning

   2. OracleAS Single Sign-On and Oracle Delegated Administration Services

3. Oracle Content DB

C.2 High Availability for Oracle Database

If you are using an Oracle RAC configuration for your Oracle Database, you must register each Oracle RAC node with Oracle Internet Directory. See "Registering Oracle Database with Oracle Internet Directory" for more information.

For complete information about high availability for the Oracle Database, see the following books in the Oracle Database documentation set:

• Oracle Real Application Clusters Installation and Configuration Guide

• Oracle Database Oracle Clusterware and Oracle Real Application Clusters Administration and Deployment Guide

• Oracle Database High Availability Overview

C.3 High Availability for Oracle Identity Management Components

For complete information about high availability for Oracle Application Server components, including Oracle Identity Management, see the following books in the Oracle Application Server documentation set:

• Oracle Application Server High Availability Guide

• Oracle Application Server Enterprise Deployment Guide

C.4 High Availability for the Oracle Content DB Middle Tier

Chapter 2, "Planning for Oracle Content DB Deployment" in Oracle Content Database Administrator's Guide provides information about high availability considerations for the Oracle Content DB middle tier.

In addition, refer to Oracle Application Server High Availability Guide and Oracle Application Server Enterprise Deployment Guide for information about high availability for middle-tier applications, including setting up load balancers.

In order to use a load balancer, you must update two Oracle Content DB properties with the appropriate host and port of the load balancer:

• IFS.DOMAIN.APPLICATION.ApplicationHost

• IFS.DOMAIN.APPLICATION.ApplicationPort

See "Managing Domain Properties" in Oracle Content Database Administrator's Guide for information about how to update these properties.

Note: OracleAS Web Cache clustering is not certified with Oracle Content DB. Additional information about using Oracle Content DB in a multiple middle tier environment is available in the white paper Best Practices for Configuring Oracle Content Database Middle Tiers for Scalability and High Availability.
