This section discusses the following topics:

3.1.1 System Requirements and Certification

Before performing any installation, read the system requirements and certification documentation to ensure that your environment meets the minimum installation requirements for the components you are installing. Both of these documents are available on Oracle Technology Network (OTN).

Oracle Fusion Middleware System Requirements, Prerequisites, and Specifications

The system requirements document covers information such as hardware and software requirements, minimum disk space and memory requirements, and required system libraries, packages, or patches:



The system requirements document also covers Oracle Universal Installer Startup Requirements.

Oracle Fusion Middleware Supported System Configurations

The certification document covers supported installation types, platforms, operating systems, databases, JDKs, and third-party products:


3.1.2 Installing and Configuring Java Access Bridge (Windows Only)

If you are installing Oracle Identity Management on a Windows 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 Web site:

  2. Install Java Access Bridge.

  3. Copy access-bridge.jar and access-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.

3.1.3 Managing the Oracle WebLogic Server Node Manager Utility for Oracle Identity Management Installations

For Oracle Identity Management Installations that require Oracle WebLogic Server, you must perform the following steps after installing Oracle WebLogic Server and before installing Oracle Identity Management:

  1. Verify the Oracle WebLogic Server Node Manager utility is stopped. If it is running, kill the process.

  2. Determine if the nodemanager.properties file is present in the WL_HOME/common/nodemanager/ directory.

    • If the nodemanager.properties file is not present, continue installing Oracle Identity Management.

    • If the nodemanager.properties file does exist, open it and verify that the ListenPort parameter is included and that it is set. If the ListenPort parameter is not included or set, edit the nodemanager.properties file so that it is similar to the following, where NODE_MANAGER_LISTEN_PORT represents the port the Node Manager listens on, such as 5556:


3.1.4 Installing Oracle Database

You must install an Oracle Database before you can install some Oracle Identity Management components, such as:

  • Oracle Internet Directory

  • Oracle Identity Federation, if you want to use an RDBMS data store

For the latest information about supported databases, visit the following Web site:


The database must be up and running to install the relevant Oracle Identity Management component. The database does not have to be on the same system where you are installing the Oracle Identity Management component.

The database must also be compatible with Oracle Repository Creation Utility (RCU), which is used to create the schemas that Oracle Identity Management components require. For information about RCU requirements, refer to the system requirements document at the following Web site:



If you are preparing a database for Oracle Single Sign-On and Oracle Delegated Administration Services 10g, ensure that Ultrasearch is installed with the 371 WKSYS Objects in the database. For more information about installing Ultrasearch for 10g components, see the metalink note 337992.1 - How to Manually Install and Uninstall Ultrasearch 10gR2 Server Components, which is available at the following Web site:

In addition, ensure that the following database parameters are set:

  • 'aq_tm_processes' >= 1

  • 'db_cache_size' >= '150994944'

  • 'java_pool_size'>= '125829120'

  • 'shared_pool_size' >= '183500800'

3.1.5 Creating Database Schema Using the Repository Creation Utility (RCU)

You must create and load the appropriate Oracle Fusion Middleware schema in your database before installing the following Oracle Identity Management components and configurations:

  • Oracle Internet Directory, if you want to use an existing schema rather than create a new one using the Installer during installation.


    When you install Oracle Internet Directory, you have the choice of using an existing schema or creating a new one using the Installer. If you want to use an existing schema, you must create it using the Repository Creation Utility (RCU) before you can install Oracle Internet Directory. If you choose to create a new schema during installation, the Installer creates the appropriate schema for you and you do not need to use the RCU.
  • Oracle Identity Federation Advanced configurations that use RDBMS for the Federation Store, Session Store, Message Store, or Configuration Store.

You create and load Oracle Fusion Middleware schema in your database using the RCU, which is available in the Oracle Fusion Middleware 11g Release 1 (11.1.1) release media and on the Oracle Technology Network (OTN) Web site. You can access the OTN Web site at:



RCU is available only on Linux x86 and Windows x86 platforms. Use the Linux RCU to create schemas on supported UNIX databases. Use Windows RCU to create schemas on supported Windows databases.

When you run RCU, create and load only the following schema for the Oracle Identity Management component you are installing—do not select any other schema available in RCU:

  • For Oracle Internet Directory, select only the Identity Management - Oracle Internet Directory schema

  • For Oracle Identity Federation, select only the Identity Management - Oracle Identity Federation schema


When you create schema, be sure to remember the schema owner and password that is shown in RCU. For Oracle Identity Federation, it is of the form PREFIX_OIF. You will need to provide this information when configuring Oracle Identity Federation with RDBMS stores.

3.1.6 Optional Environment-Specific Preparation

This topic describes optional environment-specific tasks you may want to perform before installing Oracle Identity Management 11g Release 1 (11.1.1). This topic includes the following sections: Using Symbolic Links

If you want to install Oracle Identity Management using symbolic links, you must create them before installation. For example, you could create symbolic links for the installation by executing the following commands:

prompt> mkdir /home/basedir
prompt> ln -s /home/basedir /home/linkdir

Then, when you run the Installer to install Oracle Identity Management, you can specify /home/linkdir as the Oracle Home.

After installation, you cannot create symbolic links to the Oracle Home. Also, you cannot move the Oracle Home to a different location and create a symbolic link to the original Oracle Home. Installing Oracle Identity Management on DHCP Hosts

If you plan to install Oracle Identity Management components on a DHCP server, you must ensure the Installer can resolve host names. This may require editing the /etc/hosts file on UNIX systems, and installing a loopback adapter on Windows systems. The following information provides general examples, you should alter these examples to make them specific to your environment.

On UNIX systems:

Configure the host to resolve host names to the loopback IP address by modifying the /etc/hosts file to contain the following entries. Replace the variables with the appropriate host and domain names: hostname.domainname hostname localhost.localdomain localhost

Confirm the host name resolves to the loopback IP address by executing the following command:

ping hostname.domainname

On Windows systems:

Install a loopback adapter on the DHCP server, which assigns a local IP address to your system.

After installing the adapter, add a line to the %SYSTEMROOT%\system32\drivers\etc\hosts file immediately after the localhost line and using the following format, where IP_address represents the local IP address of the loopback adapter:

IP_address   hostname.domainname   hostname Installing Oracle Identity Management on a Multihomed System

You can install Oracle Identity Management components on a multihomed system. A multihomed system is associated with multiple IP addresses, typically achieved by having multiple network cards on the system. Each IP address is associated with a host name and you can create aliases for each host name.

The Installer retrieves the fully qualified domain name from the first entry in /etc/hosts file on UNIX, or the %SYSTEMROOT%\system32\drivers\etc\hosts file on Windows. For example, if your file looks like the following, the Installer retrieves myhost1.mycompany.com for configuration: localhost.localdomain localhost
10.222.333.444 myhost1.mycompany.com myhost1
20.222.333.444 devhost2.mycompany.com devhost2

For specific network configuration of a system component, refer to the individual component's documentation listed in "Related Documents"for more information.
