System Requirements

Completing a quick, successful installation depends on the local system satisfying the software dependencies and space requirements for Oracle software. This chapter describes the requirements for installing Oracle Internet Directory on AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Solaris Intel, and Sun SPARC Solaris and any restrictions with this release. Before starting the installation, verify that your system meets the requirements described in this chapter.

This chapter contains these topics:

• Installation Overview

• System Installation Requirements

• Installation-Specific Issues and Restrictions

Installation Overview

Installing Oracle Internet Directory involves the following steps:

1. Satisfy Prerequisites: Make sure the local system satisfies the hardware, software, memory, and disk space requirements for the products you want to install. These requirements and restrictions are described in this chapter.

2. Pre-Installation: Make sure the UNIX environment is properly set up and complete the pre-installation tasks for the products you want to install. See Chapter 2, "Pre-Installation".

3. Install: Use the Oracle Universal Installer provided on your software CD-ROM to install Oracle Internet Directory. See Chapter 3, "Installation".

4. Post-Installation: Create database objects, establish the user environment, and configure the installed Oracle products for the local system. See Chapter 4, "Post-Installation".

System Installation Requirements

Verify that your system meets the requirements described in the following sections before you install Oracle Internet Directory Release 2.1.1.

• Hardware Requirements

Online Documentation Requirements

To view online documentation, use a web browser such as Netscape Navigator 4.0 or higher running on a UNIX system. To view PDF documents, you need Adobe Acrobat Reader version 3.0 or higher.

Additional Oracle Internet Directory-Specific Installation Requirements

Oracle Internet Directory Release 2.1.1 requires an installation of various components of Oracle8i Enterprise Edition, Release 8.1.7, with character set UTF8 and an instance dedicated to Oracle Internet Directory. If this installation does not already exist, then the Oracle Universal Installer installs the required components automatically as part of the Oracle Internet Directory installation. Determine the database character by the following SQL Command:

select value from nls_database_parameters
where parameter = 'NLS_CHARACTERSET' ;

Installation-Specific Issues and Restrictions

The following issues and restrictions can affect the installation or use of Oracle Internet Directory on AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Solaris Intel, and Sun SPARC Solaris. Check the Release Notes in the $ORACLE_HOME/relnotes directory before using Oracle Internet Directory.

Using Hummingbird Exceed

If you use Hummingbird's Exceed X-windows emulator while installing and using Oracle Internet Directory, set the window manager to run in Native mode so that Microsoft windows functions as the window manager.

New ORACLE_HOME

Oracle Corporation recommends that you install Oracle Internet Directory Release 2.1.1 products into a new ORACLE_HOME. Do not install Oracle Internet Directory Release 2.1.1 into an ORACLE_HOME directory that already contains Oracle products.

If you must install Oracle Internet Directory Release 2.1.1 into an ORACLE_HOME that contains Oracle Release 8.1.5 or 8.1.6 products, remove the Release 8.1.5 or 8.1.6 products by using Oracle Universal Installer before beginning the new installation.

Java Runtime Environment (JRE)

The JRE, certified for use with Oracle Internet Directory on your platform, enables Oracle Java applications such as the Oracle Universal Installer. Certified versions of JRE are supported to run with these applications. Do not modify the JRE, unless it is done through a patch provided by Oracle Support Services.

The inventory can contain multiple versions of the JRE, each of which can be used by one or more products or releases. The first time you use Installer creates the oraInventory directory which stores installation information for products that it installs on your system. The location of oraInventory is defined in /var/opt/oracle/oraInst.loc.

Products in an ORACLE_HOME access the JRE through a symbolic link in $ORACLE_HOME/JRE to the actual location of a JRE within the inventory. Do not modify the symbolic link unless it is done through a patch provided by Oracle Support Services.

The Sun SPARC Solaris patches listed in Table 1-14 and Table 1-15 are required or recommended for JRE 1.1.8_10 and can be obtained from:

http://sunsolve.sun.com

Table 1-14 Solaris 2.6 (5.6) Patches for JRE 1.1.8_10

Table 1-15 Solaris 7 (5.7) Patches for JRE 1.1.8_10

Table 1-16 Solaris 2.6 (5.6) Patches for JDK 1.2.2

Table 1-17 Solaris 7 (5.7) Patches for JDK 1.2.2

Solaris Intel systems require the patches listed in Table 1-18 for JRE Release1.1.8.10. They are available at:

http://sunsolve.sun.com

Table 1-18 Solaris Intel Patches for JDK 1.2.2

Character Mode

You can no longer install using character mode. However, you can configure the Oracle Universal Installer to perform a non-interactive installation of Oracle products. The Installer can be run in non-interactive mode directly from your system's X-windows console or via an X-terminal or PC X-terminal on a remote system. For more information on the non-interactive installation of Oracle products, see "Non-Interactive (Silent) Installation and Configuration".

File Systems

Oracle8i Server must be able to verify that file writes are made to disk. Oracle does not support file systems that do not support this verification.

Solaris 2.3, 2.4, and 2.5

Oracle does not support Solaris 2.3, 2.4, and 2.5 for use with Oracle Internet Directory Release 2.1.1. You must use Solaris 2.6 or Solaris 7. See Table 1-3 for details of operating system and patch level requirements.
