This chapter describes the prerequisites for deploying Oracle Identity and Access Management on multiple hosts. This preparation includes network, storage, servers, and database.
This chapter includes the following topics:
You must configure several virtual servers and associated ports on the load balancer for different types of network traffic and monitoring. These virtual servers should be configured to the appropriate real hosts and ports for the services running. Also, the load balancer should be configured to monitor the real host and ports for availability so that the traffic to these is stopped as soon as possible when a service is down. This ensures that incoming traffic on a given virtual host is not directed to an unavailable service in the other tiers.
For more information about preparing your network, see the "Preparing the Network for an Enterprise Deployment" chapter in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
The Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management describes the following topics:
Virtual server names used by the topology
Note:
For Oracle Identity Manager (OIM) Only HA deployment, you require VIPs for the Administration Server,wls_oim1, wls_oim2, wls_soa1, and wls_soa2.
For Oracle Access Manager (OAM) Suite Only HA deployment, you require VIP for the Administration Server only.
Load balancer configuration
IP address and virtual IP address requirements
Firewalls and ports
Management of Oracle Access Manager communication protocol
It is important to set up your storage in a way that makes Identity and Access Management deployment easier to understand, configure, and manage. Oracle recommends that you set up your file system according to information provided in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
For more information about preparing the file system, see the "Preparing Storage for an Enterprise Deployment" chapter in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
Use the recommendations as a reference to help understand the directory variables used in the installation and configuration procedures. Other directory layouts are possible and supported, but the model adopted in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management is chosen for maximum availability, providing both the best isolation of components and symmetry in the configuration and facilitating backup and disaster recovery.
The Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management describes the following topics:
Before you deploy Oracle Fusion Middleware on new hardware, you must set up the servers you plan to use so that the Oracle Software can work in an optimum fashion. Specifically, you must ensure that:
The servers are running a certified operating system with the required software patches installed.
You have configured the UNIX Kernel correctly.
You have created Users and Groups to own the Oracle software.
For more information about preparing the servers, see the "Configuring the Servers for an Enterprise Deployment" chapter in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
Use the settings described in the above document as only a guide. After using your Oracle software, you should use operating system utilities to tune the configuration to ensure that you are maximizing the potential of your servers.
The Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management describes the following topics:
Verifying server and operating System
Meeting hardware and software requirements
Meeting operating system requirements
Enabling unicode support
Enabling virtual IP addresses (optional)
Mounting shared storage onto the host
Configuring users and groups
The Identity and Access Management components in the deployment use database repositories.
You must complete the following steps:
Verify the database requirements, as described in "Verifying the Database Requirements for an Enterprise Deployment" in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
Install and configure the Oracle database repositories, as described in "Installing the Database for an Enterprise Deployment" in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
Create database services, as described in "Creating Database Services" in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
Ensure that you have prepared your database for running the Repository Creation Utility (RCU), as described in Section 2.5, "Preparing the Database for Repository Creation Utility (RCU)".
Ensure that you have created the required Identity and Access Management schemas in the database using the Repository Creation Utility (RCU), as described in Section 2.6, "Running Oracle Identity and Access Management Repository Creation Utility (Oracle Identity and Access Management RCU)".
For information on creating Identity and Access Management schemas in an Oracle RAC Database, refer to the "Loading the Identity and Access Management Schemas in the Oracle RAC Database by Using RCU" topic in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
Whenever you add a new component to the configuration, you must back up the database, as described in "Backing Up the Database" in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity and Access Management.
Perform this backup after creating domains or adding components such as Oracle Access Management or Oracle Identity Manager.
