This section includes information that you should review before installing Oracle Unified Directory. It covers the following topics:
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. Both of these documents are available on Oracle Technology Network (OTN):
This document contains information related to hardware and software requirements, minimum disk space and memory requirements, and required system libraries, packages, or patches.
This document contains information related to supported installation types, platforms, operating systems, databases, JDKs, and third-party products.
On Windows systems you cannot install the Oracle Unified Directory software if you do not have administrator privileges.
Before running the installer, set the
DISPLAY environment variable on your system.
On UNIX systems, installation as the root user is unsupported.
The Oracle Unified Directory software treats global, full local, and sparse zones as an independent physical system. Installing Oracle Unified Directory in any type of Solaris zone is therefore like installing on an independent system. Oracle Unified Directory does not share services or file locations with other zones.
Oracle Unified Directory can function in one of three modes:
As an LDAP directory server, used to contain data.
As an LDAP proxy server, where the server acts as an interface between the client and the directory server that contains the data.
As a replication gateway between Oracle Unified Directory and Oracle Directory Server Enterprise Edition.
The following sections describe which Oracle Unified Directory installation mode you should use, based on your requirements.
As a general rule, the use of the generic term server applies to the directory server, the proxy server, and the replication gateway.
Install the Oracle Unified Directory directory server if you want to create an LDAP directory server that contains directory data. For more information, see Chapter 3, "Setting Up the Directory Server".
When you install Oracle Unified Directory as an LDAP proxy server, the server acts as an interface between the client and the remote LDAP server containing the data. The proxy server manages the client requests through load balancing and/or data distribution. The proxy does not contain any data. The proxy can also manipulate the data sent by the client or received from the remote LDAP servers (For example: DN renaming, RDN changing, transformation, or Enterprise User Security).
To install the Oracle Unified Directory in proxy mode, see the procedure in Chapter 4, "Setting Up the Proxy Server".
When you use the Oracle Unified Directory proxy, your data is stored in one or more remote LDAP servers or data centers, which can be any LDAPv3-compliant directory server, such as the Oracle Unified Directory directory server or Oracle Directory Server Enterprise Edition.
When you install Oracle Unified Directory as a replication gateway, the server acts as a gateway that allows you to replicate between Oracle Directory Server Enterprise Edition and Oracle Unified Directory. For more information, see Chapter 5, "Setting Up the Replication Gateway".
You must provide Oracle Unified Directory with information about the location of the Java installation that should be used by setting the
JAVA_HOME environment variable. The setup will not work if the
JAVA_HOME environment variable is not set, or does not point to the root of a valid (at least Java 1.6) installation.
If you are using IBM WebSphere Application Server and want to use the JVM shipped with IBM WebSphere then you must verify that the JVM is certified with Oracle Unified Directory. For more information, see Section 1.1, "System Requirements and Certification".
On UNIX Systems, run a command similar to the following, depending on your shell:
$ export JAVA_HOME=/usr/lang/JAVA/jre1.6
On Windows Systems:
Right click on the Computer icon on your Desktop and select Properties.
In the System window select Advanced system settings in the left pane.
In the System Properties window select the Advanced tab and click Environment Variables.
In the Environment Variables window, click New under the User variables pane.
In the New User Variable window, enter the following information:
Variable name: Enter
Variable value: Enter the path to a valid Java installation (at least Java 6. For example, C:\Progra~1\Java\jre1.6.0_20
You can also set the
JAVA_HOME by running a command similar to the following:
During the software installation, you are asked to specify several installation directories. It is helpful to have an understanding of those directories and what they contain when installation is complete. The following directories are created:
This can be any directory on your system. The directory is empty before you install the product.
This is the directory into which Oracle Unified Directory, WebLogic Server, and the Application Development Framework are installed. Oracle WebLogic Server and the Application Development Framework must be installed if you plan to manage Oracle Unified Directory by using Oracle Directory Services Manager (ODSM).
If you are using IBM WebSphere as the application server with the Application Development Framework and Oracle Directory Services Manager, specify a directory that you wish to use as the Middleware home. This directory has no relation to the location of your WebSphere installation. If you specify a directory location that does not already exist, the installer will create the directory for you.
MIDDLEWARE-HOME directory and the
OUD Base Location Home (defined during the Oracle Unified Directory installation) are the same directory.
MIDDLEWARE-HOME directory ultimately contains the following main product directories:
Contains the Oracle Unified Directory setup files to set up individual instances. Also contains the default schema files for all server instances associated with that
OUD_ORACLE_HOME directory is
Contains Web Logic Server.
Contains the Application Development Framework.
Contains the Oracle Coherence data grid software, if you have elected to install this alongside Web Logic Server.
A complete breakdown of the directory contents after installation is provided below:
install-dir MIDDLEWARE-HOME coherence_3.7 domain-registry.xml logs modules ocm.rsp Oracle_OUD1 oracle_common registry.dat registry.xml user_projects utils wlserver_10.3
When you install the IBM WebSphere software, you are prompted for the location where you want to install the software. For the purposes of this documentation, this location is later referred to as the WAS Home, or
WAS_HOME in examples.
If you accept the default values that are provided during the installation, then the
WAS_HOME is installed in the following directory structure:
WAS_HOME for the IBM WebSphere software on the same host where you plan to install the Oracle Fusion Middleware software. Make a note of this path. You will be asked to identify the location of the IBM WebSphere directory when you configure Oracle Fusion Middleware.
