4 Installing Oracle Components

Enterprise Edition, Standard Edition, or Personal Edition Installations

The installation windows that appear when you select Enterprise Edition, Standard Edition, or Personal Edition depend upon your computer configuration and which Oracle components are currently installed.

1. From the Database Configuration Types window, select a database confutation that meets your needs. Table 4-3 describes the available configuration environments.

   Table 4-3 Database Configuration Environments

   If You Select...	Then Oracle Universal Installer...
   General Purpose	Automatically starts Database Configuration Assistant to install a preconfigured database optimized for general purpose usage. At the end of the database creation process, you are required to change the SYS and SYSTEM passwords.
   Transaction Processing	Automatically starts Database Configuration Assistant to install a preconfigured database optimized for transaction processing environment. At the end of the database creation process, you are required to change the SYS and SYSTEM passwords.
   Data Warehouse	Automatically starts Database Configuration Assistant to install a preconfigured database optimized for data warehousing environment. At the end of the database creation process, you are required to change the SYS and SYSTEM passwords.
   Customized	Automatically starts Database Configuration Assistant to enable the creation of a customized database. At the end of the database creation process, you are required to change the SYS and SYSTEM passwords. This option takes longer than the preconfigured options. Continue to step 3.
   Software Only	Installs software only and does not run any configuration tools. Select this option if your computer barely meets the minimum memory requirements. Manually start Database Configuration Assistant and Oracle Net Configuration Assistant after installation to install and configure your database and Oracle Net Services environment. Continue to step 10. See Also: "Installations Meeting Minimal Memory Requirements"

   
   

2. If Microsoft Transaction Server is detected, then the Oracle Services for Microsoft Transaction Server window appears. Enter a port number for this service.

3. Choose Next.

   The next window depends on whether or not an existing database is detected:

   • If a pre-9.2 Oracle database is detected on your computer, then the Upgrading an Existing Database window appears. Optionally, select to upgrade your database with Oracle Database Upgrade Assistant. Continue to step 4.

   • If an Oracle database is not detected on your computer, then the Database Identification window appears and prompts you to select a preconfigured database type. Go to step 5.

     
     

     Note: Do not upgrade an Oracle9i database configured for use with Oracle Internet Directory through this installation type. Oracle9i database and Oracle Internet Directory upgrades must be performed by following the procedures in "Oracle Internet Directory Installations".

     
     

4. Select whether or not to upgrade your database to the latest release.

   To upgrade an existing database:

   1. Select the Upgrade an Existing Database check box and the SID of the database to upgrade to the latest Oracle9i database release.

   2. Choose Next.

      The Summary window appears.

   3. Continue to step 11.

   To install a new database:

   1. Do not select the Upgrade an Existing Database check box.

   2. Choose Next.

      The Database Identification window appears.

   3. Go to step 5.

5. Enter the global database name and SID in the fields provided. If you selected to configure a Customized database environment, then go to step 10. If you are upgrading an existing database, then go to step 8.

   This information is used when Database Configuration Assistant creates your database after installation.

   
   

   Note: For Oracle Real Application Clusters, the SID you enter is automatically appended with an identifier. For example, if DB is entered, the first instance in the cluster is given a SID of DB1, and the second instance is given a SID of DB2.

   
   

6. Choose Next.

   The Database File Location window appears.

7. Enter the directory location for the database files. The directory location must be a mapped drive.

8. Choose Next.

   The Database Character Set window appears.

9. Choose the database character set from the available options. By default, the database character set is automatically chosen based on the locale setting of the operating system.

10. Choose Next.

    The Summary window appears.

11. Review the space requirements to ensure that you have enough disk space and choose Install.

12. If you are installing from the CDs, then you are prompted to insert the subsequent disks to continue with installation.

13. Wait until the selected components are installed.

    The Configuration Tools window appears at the end of installation.

DRIVE_LETTER:\ORACLE_BASE\ORACLE_HOME\wf\install> wfinstall.bat 

Reviewing the Installation Session Log

The first time the Installer runs it creates the SYSTEM_DRIVE:\Program Files\Oracle\Inventory\logs directory. An inventory of installed components and installation actions performed are kept in this directory.

Log filenames take the form installActionsdate_time.log (for example, installActions2001-07-14_09-00-56-am.log).

You can also view a list of installed components by choosing Installed Products on any window of Oracle Universal Installer. A window of installed programs appears.

Stopping Oracle Services on Windows Platforms

You must first stop the Oracle Windows services before deinstalling Oracle components or removing any registry entries.

To stop Windows services:

1. Open the Services control panel:

   • On Windows NT, choose Start > Settings > Control Panel > Services.

   • On Windows 2000, choose Start > Settings > Control Panel> Administrative Tools > Services.

   • On Windows XP, choose Start > Control Panel > Administrative Tools > Services.

2. If any Oracle services (names begin with Oracle or Ora) exist and have the status Started, select the service, and choose Stop.

3. Choose Close to exit the Services window.

4. Exit the Control Panel.

Deinstalling Components with Oracle Universal Installer

This section describes how to use Oracle Universal Installer to deinstall Oracle components (which deinstalls them from the installer inventory) instead of removing them manually.

Do not delete an Oracle home manually (for example, by deleting the directory structure with Windows Explorer or MS-DOS command prompt) because the components in that Oracle home remain registered in the Oracle Universal Installer inventory. If you then attempt an installation in the same Oracle home, some or all of the components selected may not be installed because the installer determines they are already installed.

Oracle Universal Installer creates Windows services for Oracle components during installation. However, the installer does not delete services created by Oracle Net Configuration Assistant, OiD Configuration Assistant, and Database Configuration Assistant.

To deinstall components with Oracle Universal Installer:

1. Ensure that you first follow the instructions in "Stopping Oracle Services on Windows Platforms".

2. Choose Start > Programs > Oracle Installation Products > Universal Installer.

   The Welcome window for Oracle Universal Installer appears.

3. Choose the Deinstall Products button.

   The Inventory window appears.

4. Expand the tree of installed components until you find the components to deinstall.

5. Check the boxes of components to deinstall.

6. Choose Remove.

   The Confirmation window appears.

7. Choose Yes to deinstall the selected components.

   
   

   Note: A message may appear indicating that removing some components may cause other components to not function properly.

   
   

   The components are deinstalled from your computer. The Inventory window appears without the deinstalled components.

8. Choose Close to close the Inventory window.

9. Choose Exit to exit Oracle Universal Installer.

Removing Oracle Keys From the Registry on Windows NT, Windows 2000, and Windows XP
