Installing Oracle Enterprise Manager and Management Packs

This chapter provides an overview of how to install Oracle Enterprise Manager and the Management Pack components.

Specific topics discussed are:

What is Oracle Universal Installer?

Oracle Universal Installer is a Java-based tool that enables you to install Oracle Components from your CD-ROM. Oracle Universal Installer provides the following capabilities:

Component and suite installations
National language/globalization support
Removal of installed components
Multiple Oracle homes support

The Oracle Universal Installer is essentially an installation wizard that walks you through a series of screens prompting you for specific information. The following sections describe a typical installation using the Oracle Universal Installer.

Using the Oracle Universal Installer

The Welcome screen is the first screen that appears when you start Oracle Universal Installer. From the Welcome screen you can:

Deinstall existing Oracle products by clicking the Deinstall Products... button
Get information about this release of the Oracle Universal Installer by clicking the About Oracle Universal Installer... button

From any of the Oracle Universal Installer screens you can:

Get information on previously installed Oracle products by clicking the Installed Products... button
Quit the installation process by clicking the Exit button
Get help on the specific Oracle Universal Installer screen by clicking the Help button
Move to the Previous screen by clicking the Previous button
Move to the Next screen by clicking the Next button

Specifying the Installation Location

The File Locations screen of the Oracle Universal Installer prompts you to enter the name and destination of the Oracle Home you will be using as an installation location. You have several installation options based on your existing system setup. The table below lists the typical installation location options:

Note:
Using the old Oracle Installer (the pre-Oracle Universal Installer shipped with releases 7.x and 8.0.x) to install components into a release 8.1 Oracle home directory is not supported. Likewise, you cannot install release 8.1.6 components into a release 7.x, 8.0.x, 8.1.3, or 8.1.4 Oracle home.

If you are installing... Your installation options are...

Oracle Enterprise Manager and the Management Packs

Install into an existing release 8.1.6 Oracle home

Install into a new Oracle home

One or more of the management packs¹

Install into an existing release 8.1.6 Oracle home that contains Oracle Enterprise Manager release 2.1

Install into a new Oracle home

Oracle Enterprise Manager only

Install into an existing release 8.1.6 Oracle home

Install into a new Oracle home

¹ Oracle Enterprise Manager release 2.1 (the base console) is automatically installed if an existing release 2.1 is not detected in the specified Oracle home.

If you are installing...	Your installation options are...
Oracle Enterprise Manager and the Management Packs	Install into an existing release 8.1.6 Oracle home Install into a new Oracle home
One or more of the management packs¹	Install into an existing release 8.1.6 Oracle home that contains Oracle Enterprise Manager release 2.1 Install into a new Oracle home
Oracle Enterprise Manager only	Install into an existing release 8.1.6 Oracle home Install into a new Oracle home

Important:
You can have only 1 installation of Enterprise Manager release 2.1 on a machine. If you already have an installation of Enterprise Manager release 2.1, make sure to install any Management Packs into the existing Oracle home. If you have multiple installations of Oracle8i or 8.1.6, make sure you deinstall all unnecessary copies of Enterprise Manager before installing any of the Management Packs.

Selecting Top-Level Components to Install

The Oracle Universal Installer allows you to install all or some of the components contained on the Oracle Enterprise Manager with Change Management, Diagnostics, and Tuning Packs CD-ROM. The Available Products screen provides two Top-Level component options:

Oracle Enterprise Manager Packs and Management Infrastructure 2.1.0.0.0
Oracle Enterprise Manager Packs 2.1.0.0.0

Chapter 1 discussed all of the components that are available from this CD-ROM. This chapter will identify which components get installed based on the installation choices you make. Both of the top-level component options allow you to select either a Typical or Custom installation from the Installation Types screen. The following table lists the two top-level component options and their installation types.

This Top-Level Component...	Consists of these installation types...
Oracle Enterprise Manager Packs and Management Infrastructure 2.1.0.0.0	Typical¹ Installs Oracle Enterprise Manager, DBA Management Pack, Diagnostics Pack, Tuning Pack, Change Management Pack, and Oracle Management Server.
	Custom Allows you to select which components to install. Select this option if you wish to install the Oracle Enterprise Manager Web Site. The web site can be used to launch the Oracle Enterprise Manager console. (Management Packs are not browser-enabled.)
Oracle Enterprise Manager Packs 2.1.0.0.0	Typical Installs Oracle Enterprise Manager, DBA Management Pack, Diagnostics Pack, Tuning Pack, and Change Management Pack. Select this Top-Level Component if you will be using an existing Oracle Management Server.
	Custom Allows you to select which components to install.

¹ For detailed information on all of the components that are associated with each of the management packs, see "Installable Components"

Selecting an Oracle Management Server Repository

If you selected Oracle Enterprise Manager Packs and Management Infrastructure 2.1.0.0.0 as your top-level component for installation, the Oracle Universal Installer will prompt you to specify whether the Oracle Management Server should use an existing repository or create a new one. The table below describes each option:

Select...	In this situation...
existing repository	You have already installed another Oracle Management Server and created a repository, and you want this Oracle Management Server to manage the same computers; therefore you want to share the repository.
new repository	You have not installed another Oracle Management Server or repository, or you want a completely separate management setup.

Note:
If you selected Oracle Enterprise Manager Packs and Management Infrastructure 2.1.0.0.0 as your top-level component for installation, the Oracle Enterprise Manager Configuration Assistant will start automatically at the end of the installation. See the Oracle Enterprise Manager Configuration Guide for more information.

Reviewing the Installation Summary

Once you have set all of your installation options, the Oracle Universal Installer shows you a Summary screen of all of the products to be installed. This summary enables you to verify that all of the components you want to install are included. Once you have verified that the summary includes all of the components you wish to install, click the Install button to begin the installation.

Note:
At the end of every installation the Net8 Configuration Assistant is launched. You can use this wizard to configure a tnsnames.ora file to set up direct database connections without using an Oracle Management Server. If you do not wish to configure your tnsnames.ora file at this time or if you will be using an Oracle Management Server for your connections, you can click Cancel to close the wizard.

Post-Installation Configuration

After the installation has completed, you may still have some additional configuration tasks to perform before using the management pack applications. For post-installation configuration information, see the documentation associated with each of the packs you have installed. (Note that some components do not require any additional configuration tasks.)

See Related Publications on page vii for information about the documents available for these management packs.
