Preinstallation Requirements

After you have verified that your system meets the requirements described in Chapter 1, "System Requirements", use this chapter when you prepare your system for installing Oracle Internet Directory.

The chapter discusses the following topics:

- Installation Differences Between Windows NT and UNIX

- Keyboard Navigation

- Preinstallation Tasks

- Preinstallation Requirements for Oracle Internet Directory

## Installation Differences Between Windows NT and UNIX

Database administrators experienced with installing Oracle components in UNIX environments must note that many manual setup tasks required on UNIX are not required on Windows NT. For example, on Windows NT, you do not need to manually:

- Set environmental variables

- Create a UNIX DBA group for database administrators

- Create a UNIX group for users running Oracle Universal Installer

- Create a UNIX account solely dedicated to installing and upgrading Oracle components

All preinstallation tasks required on Windows NT are described in this chapter.

## Keyboard Navigation

Windows operating systems include a series of keyboard commands that can be used with Oracle Universal Installer. For example, the tab key enables you to navigate from item to item in a window. Oracle Universal Installer includes several windows that require navigation through components in a hierarchical tree. These windows include:

- Available Product Components window (lists the components available for installation)

- Summary window (lists the components about to be installed)

- Inventory window (lists the installed components)

Table 2-1 describes how to navigate these windows with keyboard commands.

##### Table 2-1 Keyboard Commands for Oracle Universal Installer

To... | Use The...
--- | ---
Move up and down a list of components | Up and down arrows
Open an expandable tree of components | Right arrow
Close an expanded tree of components | Left arrow
Select or deselect a component | Space bar

## Preinstallation Tasks

Perform the following tasks before installing Oracle components.

To perform preinstallation tasks:

1. Start your operating system.

2. If you are installing on Windows NT, log on as a member of the Administrators group to the computer on which to install Oracle components.

   Note: Do not manually set ORACLE_HOME in the environment. This is automatically done in the registry. Setting ORACLE_HOME in the environment is not necessary or recommended and prevents multiple Oracle home environments from functioning properly. See Chapter 3, "Multiple Oracle Homes and Optimal Flexible Architecture" of the Oracle8i Administrator's Guide for Windows NT for more information.

3. Ensure that you have backed up any databases to migrate or upgrade.

4. If applicable, install and test your network hardware and software.

5. Stop all Oracle services (if any are running) for the Oracle home into which you want to install Oracle components:

1. Choose Start > Settings > Control Panel > Services.

2. If any Oracle services (their names begin with Oracle) exist and have the status Started, select the service and choose Stop. In particular, ensure that the Oracle listener service (named OracleHOME_NAMETNSListener for 8.1 databases, OracleTNSListener80 for 8.0 databases, or OracleTNSListener for 7.3 databases) is stopped.

3. Choose Close to exit the Services window.

1. Insert the component CD-ROM into your CD-ROM drive.

2. From the DOS prompt, enter the following:

       DRIVE_LETTER: \SETUP.EXE

   Note: You can also launch the executable file by navigating through Windows Explorer and then double-clicking on `setup.exe`

## Preinstallation Requirements for Oracle Internet Directory

Table 2-2 identifies requirements that must be met before installation.

##### Table 2-2 Preinstallation Requirements for Oracle Internet Directory

Issue | Requirement | See Also...
--- | --- | ---
Upgrading | If you are upgrading Oracle8i database release 8.1.6 and Oracle Internet Directory release 2.0.6 to releases 8.1.7 and 2.1.1, respectively, ensure that you: Stop the Oracle listener service, Oracle database service, and Oracle Internet Directory service Know the system identifier (SID), Oracle directory server (ODS) user password, and Oracle Internet Directory administrator password of the Oracle8i database to upgrade Perform a complete backup prior to upgrade There is no network downtime during Oracle Internet Directory upgrade in a multinode replication environment. The other nodes are available while the upgrade of one node is in progress. In a replicated environment, Oracle Internet Directory 2.1.1 running on one node can coexist with other nodes running Oracle Internet Directory 2.0.6. Review all guidelines for upgrading a multinode replication network before upgrading. Note: LDAP Data Interchange Format (LDIF)-based manual upgrading is available as an alternative to automatically upgrading Oracle Internet Directory through Oracle Universal Installer. | Chapter 3 of Oracle Internet Directory Administrator's Guide
Upgrading | If you installed Oracle8i database 8.1.6 and Oracle Internet Directory 2.0.6 during separate installation sessions, do not upgrade them together during the same installation session. Instead, upgrade them during separate installation sessions. First, upgrade the Oracle8i database to release 8.1.7 (for example, by selecting the database server's Typical installation type). Oracle Universal Installer prompts you to automatically upgrade your Oracle8i database to release 8.1.7. After database upgrade is complete, upgrade Oracle Internet Directory to release 2.1.1 through the Oracle Internet Directory installation type. Enter the SID of the just-upgraded database when prompted. Oracle Universal Installer only upgrades Oracle Internet Directory. | Chapter 3 of Oracle Internet Directory Administrator's Guide
Currently installed Oracle8i database | If you have an Oracle8i database, release 8.1.7, configured with a UTF8 character set installed, you can install Oracle Internet Directory 2.1.1 in the same Oracle home. To do so, ensure that both the database and listener are running. | Chapter 3, "Installation"
Downgrading | You cannot downgrade Oracle Internet Directory 2.1.1 to 2.0.6. |
UTF8 character set | Oracle Internet Directory requires the Oracle8i database to use the UTF8 character set. If an Oracle8i database is not currently installed, Oracle Corporation recommends that you create one as part of the Oracle Internet Directory installation type. If you have a database already, make sure that it uses the UTF8 character set. | Chapter 3, "Installation"
