2 Preparing to Install

This chapter provides information you should review before installing Oracle Identity and Access Management 11g Release 2 (

This chapter discusses the following topics:

2.1 Reviewing System Requirements and Certification

Before performing any installation, you should read the system requirements and certification documents to ensure that your environment meets the minimum installation requirements for the products you are installing.

  • Oracle Fusion Middleware System Requirements and Specifications

    This document contains information related to hardware and software requirements, minimum disk space and memory requirements, and required system libraries, packages, or patches.

  • Oracle Fusion Middleware Supported System Configurations

    This document contains information related to supported installation types, platforms, operating systems, databases, JDKs, and third-party products.

  • For interoperability and compatibility issues that may arise when installing, refer to Oracle Fusion Middleware Interoperability and Compatibility Guide.

    This document contains important information regarding the ability of Oracle Fusion Middleware products to function with previous versions of other Oracle Fusion Middleware, Oracle, or third-party products. This information is applicable to both new Oracle Fusion Middleware users and existing users who are upgrading their existing environment.

2.2 Installing and Configuring Java Access Bridge (Windows Only)

If you are installing Oracle Identity and Access Management on a Windows operating system, you have the option of installing and configuring Java Access Bridge for Section 508 Accessibility. This is only necessary if you require Section 508 Accessibility features:

  1. Download Java Access Bridge from the following URL:

  2. Install Java Access Bridge.

  3. Copy access-bridge.jar and jaccess-1_4.jar from your installation location to the jre\lib\ext directory.

  4. Copy the WindowsAccessBridge.dll, JavaAccessBridge.dll, and JAWTAccessBridge.dll files from your installation location to the jre\bin directory.

  5. Copy the accessibility.properties file to the jre\lib directory.

2.3 Identifying Installation Directories

This topic describes directories you must identify in most Oracle Identity and Access Management installations and configurations.

The common directories described in this section include the following:

For more information about the common directories and basic concepts of Oracle Fusion Middleware and Oracle WebLogic Server, refer to "Understanding Oracle Fusion Middleware Concepts" in the Oracle Fusion Middleware Administrator's Guide.

2.3.1 Oracle Middleware Home Location

Identify the location of your Oracle Middleware Home directory. The Installer creates an Oracle Home directory for the component you are installing under the Oracle Middleware Home that you identify in this field. The Oracle Middleware Home directory is commonly referred to as MW_HOME.

2.3.2 Oracle Home Directory

Enter a name for the Oracle Home directory of the component. The Installer uses the name you enter in this field to create the Oracle Home directory under the location you enter in the Oracle Middleware Home Location field.

The Installer installs the files required to host the component, such as binaries and libraries, in the Oracle Home directory. In examples, the Oracle home path is identified with the ORACLE_HOME variable.

This directory is also referred to as IAM_HOME in this book.


Avoid using spaces in the directory names, including Oracle Home. Spaces in such directory names are not supported.

2.3.3 Oracle Common Directory

The Installer creates this directory under the location you enter in the Oracle Middleware Home Location field.

The Installer installs the Oracle Java Required Files (JRF) required to host the components, in the Oracle Common directory. There can be only one Oracle Common Home within each Oracle Middleware Home. In examples, the Oracle Common directory is identified with the oracle_common variable.

2.3.4 Oracle WebLogic Domain Directory

A WebLogic domain includes a special WebLogic Server instance called the Administration Server, which is the central point from which you configure and manage all resources in the domain. Usually, you configure a domain to include additional WebLogic Server instances called Managed Servers. You deploy Java components, such as Web applications, EJBs, and Web services, and other resources to the Managed Servers and use the Administration Server for configuration and management purposes only.

Managed Servers in a domain can be grouped together into a cluster.

The directory structure of a domain is separate from the directory structure of the WebLogic Server home. It can reside anywhere; it need not be within the Middleware home directory. A domain is a peer of an Oracle instance.

By default, the Oracle Fusion Middleware Configuration Wizard creates a domain in a directory named user_projects under your Middleware Home(MW_HOME).

2.3.5 WebLogic Server Directory

Enter the path to your Oracle WebLogic Server Home directory. This directory contains the files required to host the Oracle WebLogic Server. In examples, it is identified with the WL_HOME variable.

2.4 Determining Port Numbers

If you want to install an Oracle Identity and Access Management 11g Release 2 ( component against an existing Oracle Identity and Access Management component, you may need to identify the ports for the existing component. For example, if you want to install Oracle Identity Manager against an existing Oracle Internet Directory instance, then you must identify its port when you install Oracle Identity Manager.

2.5 Locating Installation Log Files

The Installer writes log files to the ORACLE_INVENTORY_LOCATION/logs directory on UNIX systems and to the ORACLE_INVENTORY_LOCATION\logs directory on Windows systems.

On UNIX systems, if you do not know the location of your Oracle Inventory directory, you can find it in the ORACLE_HOME/oraInst.loc file.

On Microsoft Windows systems, the default location for the inventory directory is C:\Program Files\Oracle\Inventory\logs.

The following install log files are written to the log directory:

  • installDATE-TIME_STAMP.log

  • installDATE-TIME_STAMP.out

  • installActionsDATE-TIME_STAMP.log

  • installProfileDATE-TIME_STAMP.log

  • oraInstallDATE-TIME_STAMP.err

  • oraInstallDATE-TIME_STAMP.log
