Preinstallation Requirements

This chapter describes installation requirements for an Oracle9i for Windows installation.

This chapter contains these topics:

• Single Oracle Home Components

• Top-Level Component System Requirements

• Mandatory Individual Component Requirements

• Database Upgrade Requirements

Single Oracle Home Components

Most Oracle components can be installed multiple times on the same computer. However, the following components are only installed once for each computer:

• Oracle Performance Monitor for Windows NT

• Oracle Objects for OLE

• Oracle Provider for OLE DB

  Notes: All Oracle7 components and all Oracle8 release 8.0.3 components are non-multiple Oracle home products.

  See Also: "Using Optimal Flexible Architecture"

If you attempt to install these components a second time, Oracle Universal Installer detects that these products are already installed in another Oracle home and automatically removes them from the installation process without prompting you. The following information is logged to the installActions.log file in the c:\Program Files\Oracle\Inventory\logs directory.

# product_name is a single oracle home product. It is already installed in 
currently_installed_location. 

If you are performing an installation and notice that one or more single Oracle home components are not available for installation during the current session, check to see if any of these components or any previous versions of these components are installed in another Oracle home. If you want to install these in the currently selected Oracle home, then first deinstall the conflicting versions.

See Also: Appendix A, "Individual Components Available for Installation" for the installation types under which these components are installed

Top-Level Component System Requirements

The following sections list the system requirements for each top-level component. Each top-level component contains several installation types, each of which contain a series of individual components. Some individual components also have requirements that must be satisfied before installation. Those requirements are described in "Mandatory Individual Component Requirements".

• System Requirements for FAT and NTFS File Systems

• Oracle9i System Requirements

• Component Certifications

  Important: The hard disk requirements for each Oracle9i top-level component include 32 MB required to install Java Runtime Environment (JRE) and Oracle Universal Installer on the partition where the operating system is installed. If sufficient space is not detected, installation fails and an error message appears.

System Requirements for FAT and NTFS File Systems

This chapter lists system requirements for both the File Allocation Table (FAT) and NT File System (NTFS) file systems. Because of the difference in space allocation on both file systems, the hard disk requirements vary.

Oracle Corporation recommends installing on NTFS for Windows NT, Windows 2000, and Windows XP or FAT32 for Windows 98.

See Also: "About NTFS File System and Windows Registry Permissions"

Note: Review the FAT and NTFS system requirements listed in this section. These values are more accurate than the hard disk values reported by the Oracle Universal Installer Installation Summary window. These windows do not include: Accurate FAT disk space values The space required to create a database The size of compressed files that are expanded on the hard drive

Oracle Enterprise Manager

All Oracle Enterprise Manager products must be of the same release. Do not upgrade Oracle Management Server and the repository until all Oracle Enterprise Manager users have upgraded their software to Oracle9i release 2 (9.2). Older versions of Enterprise Manager are not supported with the new release.

Review the following requirements before beginning installation of Oracle Enterprise Manager components:

• Oracle Management Server Requirements

• Oracle Enterprise Manager Web Site Requirements

• Oracle Enterprise Manager Paging Server Requirements

  See Also: Oracle Enterprise Manager Configuration Guide for additional Enterprise Manager system requirements and certifications

Oracle Management Server Requirements

Prior to installing Oracle Management Server, determine whether you will use an existing Oracle Enterprise Manager repository or create a new Oracle Enterprise Manager repository.

Use an Existing Repository

If the existing repository is release 2 (9.2), then no further preinstallation steps are required.

If the existing repository is release 2.x, then upgrade the older repository to the current release by running Oracle Enterprise Manager Configuration Assistant after installation.

Create a New Repository

To create a new release 2 (9.2) repository, install and start a database (or select an existing, running database to which you have access) in which to create a new repository. Optionally, if the database software is detected in the Oracle home where Oracle Management Server is installed, then when Oracle Enterprise Manager Configuration Assistant starts, choose to have the assistant create a new database instance and automatically create the repository in that new instance. The following database versions have been certified for the release 2 (9.2) repository: 9.2, 9.0.1, and 8.1.7.

Oracle Enterprise Manager Configuration Assistant automatically starts during the configuration phase of the following installation types: Custom Oracle9i Database, Oracle Management Server, and Custom Oracle9i Management and Integration. For all other installation types, manually start Oracle Enterprise Manager Configuration Assistant to configure Oracle Management Server. After installation, Oracle Enterprise Manager Configuration Assistant is available from Start > Oracle - HOME_NAME > Configuration and Migration Tools > Enterprise Manager Configuration Assistant.

See Also: "General Repository Guidelines" of Oracle Enterprise Manager Configuration Guide for details on repository creation, initial size of a release 2 (9.2) repository, and guidelines on how much it can grow

Oracle Enterprise Manager Web Site Requirements

Install Oracle Enterprise Manager Web Site to run Oracle Enterprise Manager Console and supported management applications from a Web browser. It also allows administrators to access reports published from Enterprise Manager Console from a central reporting Web site. Oracle Enterprise Manager Web Site requires 820 MB of available hard disk space. By default, Oracle Enterprise Manager Web Site bundles a preconfigured Oracle HTTP Server to act as its Web listener. However, Web-enabled Oracle Enterprise Manager also supports the following additional Web servers (although any Web server using a standard common gateway interface (CGI) can support Oracle Enterprise Manager release 2 (9.2)):

• Oracle Internet Application Server release 1.0 or higher for Windows NT and Windows 2000

• Microsoft Internet Information Server (IIS) release 4.0 or higher for Windows NT and IIS 5.0 or higher for Windows 2000

• Oracle HTTP Server release 1.3.22 or higher for Windows NT, Windows 2000, and Windows XP

• Apache release 1.3.22 or higher for Windows NT and Windows 2000

  See Also: Oracle Enterprise Manager Configuration Guide for more information about Oracle Enterprise Manager Web Site The appropriate Web server documentation for additional system requirements

Oracle Enterprise Manager Paging Server Requirements

Install Oracle Enterprise Manager Paging Server on a computer with a modem. A modem is required in order to send event and job status changes to the pager of an Oracle Enterprise Manager administrator.

Oracle Internet Directory

This section contains these topics:

• Upgrading Oracle Internet Directory

• Installing Oracle Internet Directory on an Existing Database

• Installing Oracle Internet Directory Release 9.2

• Downgrading Oracle Internet Directory

Upgrading Oracle Internet Directory

Oracle Internet Directory upgrade is supported from Oracle Internet Directory release 2.1.1.x and 3.0.1.x. If the Oracle home where you intend to perform the upgrade of Oracle Internet Directory also contains a complete Enterprise Edition installation, then you must perform the Oracle Internet Directory upgrade before the Enterprise Edition upgrade.

There is no network downtime during Oracle Internet Directory upgrade in a multinode replication environment when you upgrade one node at a time. The other nodes are available while the upgrade of one node is in progress.

Installing Oracle Internet Directory on an Existing Database

If you have Oracle9i release 2 (9.2) installed on a computer and you now want to install Oracle Internet Directory release 9.2 in the same Oracle home, ensure that both the database and listener are running.

Installing Oracle Internet Directory Release 9.2

To install Oracle Internet Directory release 9.2, choose the Oracle Internet Directory installation type from the Oracle9i Management and Integration top-level component; this creates the correct underlying Oracle9i database as part of Oracle Internet Directory release 9.2 installation.

Downgrading Oracle Internet Directory

You cannot downgrade Oracle Internet Directory release 9.2 to 3.0.1.x or 2.1.1.x.

See Also: "Oracle Internet Directory Installations" Oracle Internet Directory Administrator's Guide

Oracle Managed Files

Configuration procedures are required in order to enable Oracle Managed Files.

See Also: "Using Oracle-Managed Files" in Oracle9i Database Administrator's Guide

Oracle Real Application Clusters

Refer to Appendix B, "Oracle Real Application Clusters Preinstallation Tasks" for hardware, software, and preinstallation requirements. You must complete these tasks before using Oracle Universal Installer.

See Also: "Oracle Real Application Clusters Upgrade Requirements" Oracle9i Database Migration

Oracle Snap-Ins to the Microsoft Management Console

Oracle9i ships several Snap-Ins for the Microsoft Management Console (MMC). MMC is a built-in feature of Windows 2000. Windows NT requires the Windows NT 4.0 Option pack. Reapply the previously installed service pack after installing the Windows NT option pack.

Install Internet Explorer version 5.0 (IE5.0) or later before installing Oracle Snap-Ins. If you install any Oracle Snap-Ins before installing IE5.0, then reinstall the Oracle Snap-Ins.

The Oracle Snap-In components that have this dependency are:

• Oracle Administration Assistant for Windows NT

• Oracle Performance Monitor for Windows NT

• Oracle Services for Microsoft Transaction Server

  Note: Installing Oracle Administration Assistant for Windows NT automatically installs each Oracle Snap-in component.

Download the MMC add-on from the following Web site:

http://www.microsoft.com/

Oracle Transparent Gateways

See Appendix C, "Oracle Transparent Gateways" for hardware, software, and preinstallation requirements.

Oracle Workflow

Ensure that you have configured the required hardware and software.

Oracle9i Integration with Active Directory

You must perform preinstallation requirements for integration to be successful.

See Also: "Using Oracle9i Directory Server Features with Active Directory" of Oracle9i Security and Network Integration Guide

Database Upgrade Requirements

Oracle Corporation recommends installing Oracle9i release 2 (9.2) into a new Oracle home directory. If you must install Oracle9i release 2 (9.2) into an Oracle home directory that contains previously installed Oracle8i components, then use Oracle Universal Installer to remove these components before beginning a new installation.

Refer to Oracle9i Database Migration before deciding to upgrade an existing database. Upgrade procedures on Windows are covered in Oracle9i Database Migration. However, this section describes several Windows-specific issues to understand before following the instructions in Oracle9i Database Migration.

The following sections describe specific upgrade requirements:

• Policies for Linking and Relinking Applications

• Upgrading Releases 7.3.4 and 8.0.6

• Downgrading a Database

• Oracle Real Application Clusters Upgrade Requirements

Policies for Linking and Relinking Applications

Oracle Corporation recommends that you upgrade your client software to match the current server software. For example, if you upgrade your Oracle server to release 2 (9.2), then Oracle corporation recommends upgrading the client software to release 2 (9.2) as well. Keeping the server and client software at the same release number ensures maximum stability for your applications. In addition, the latest Oracle client software may provide added functionality and performance enhancements that were not available with previous releases.

See Also: Oracle9i Database Migration for rules regarding linking and relinking applications when you perform a feature release upgrade of the client software

Upgrading Releases 7.3.4 and 8.0.6

Before using the Migration utility or Oracle Data Upgrade Assistant to upgrade to the latest release, an Oracle7 database must be at least release 7.3.4 and an Oracle8 database must be at least release 8.0.6. See the documentation that accompanied your previous database release for information on how to upgrade to release 7.3.4 or 8.0.6.

Oracle Command Line Tools with the Migration Utility

If you use the Migration utility to upgrade your Oracle database, the instructions in Oracle9i Database Migration prompt you to enter information at the command prompt of an Oracle tool. The command tool to use (SQL*DBA, Server Manager, or SQL*Plus) depends upon the database release from which you are upgrading. Table 2-4 describes the tools to use and the method for starting these tools:

Table 2-4 Oracle Command Line Tools  

If Upgrading from Oracle Release...	Use...	By Entering...
7.3.4	Server Manager	C:\> SVRMGR23
8.0.6	Server Manager	C:\> SVRMGR30
8.1.7	Server Manager or SQL*Plus	C:\> SVRMGRL or C:\> SQLPLUS
9.0.1	SQL*Plus	C:\> SQLPLUS

If you use the Migration utility to upgrade your Oracle database, the instructions in Oracle9i Database Migration also prompt you to use the ORADIM utility at the MS-DOS command prompt. The ORADIM utility creates, starts, stops, and modifies database instances on Windows NT. Table 2-5 describes the method for starting the ORADIM utility depending upon the database release from which you are upgrading:

Table 2-5 ORADIM Versions  

If Upgrading from Oracle Release...	Use...	By Entering...
7.3.4	ORADIM73	C:\> ORADIM73 OPTIONS
8.0.6	ORADIM80	C:\> ORADIM80 OPTIONS
8.1.7	ORADIM	C:\> ORADIM OPTIONS
9.0.1	ORADIM	C:\> ORADIM OPTIONS

See Also: "Postinstallation Database Creation" of Oracle9i Database Administrator's Guide for Windows for more information on using the ORADIM utility

Required Oracle7 Server SQL*Net Patch Releases

When upgrading from Oracle7 Server release 7.3.4 to the latest release, install the appropriate patch of SQL*Net in the 7.3.4 Oracle home before upgrading with either Oracle Data Upgrade Assistant or the Migration utility. Upgrade fails if you do not install the appropriate patch of SQL*Net.
