Before You Install Oracle9i

Perform the following tasks before installing Oracle components:

  1. Read the appropriate online documentation described in "What Documentation Do I Read First?" before you begin installation.

  2. Review and satisfy applicable system and component requirements in Chapter 2, "Preinstallation Requirements" before you begin installation.

  3. Log on as a member of the Administrators group to the computer on which to install Oracle components.

  4. Delete the ORACLE_HOME environment variable if it exists. Refer to your Microsoft online help for more information about deleting environment variables.


    Note:

    The ORACLE_HOME environment variable is automatically set in the registry. Manually setting this variable prevents installation.

  5. If you are installing in an existing Oracle9i release 1 (9.0.1) or release 2 (9.2.0) home, stop all Oracle services:

    • 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.

    1. If any Oracle services (their names begin with "Ora") exist and have the status Started, select the service.

    2. Choose Stop on Windows NT, or choose Action > Stop on Windows 2000.

      In particular, ensure that the Oracle listener service is stopped. This service is named OracleHOME_NAMETNSListener for release 8.1 databases, OracleTNSListener80 for release 8.0 databases, or OracleTNSListener for release 7.3 databases.

    3. Choose Close to exit the Services window.

  6. Continue to the "Beginning Your Oracle9i Installation" section.

Beginning Your Oracle9i Installation

Using the old Oracle Installer (Installer shipped with releases 7.x and 8.0.x) to install components into an Oracle9i release 2 (9.2) Oracle home directory is not supported. Likewise, you cannot install release 2 (9.2) components into a release 7.x, 8.0.x, or 8.1.x Oracle home.

Note:

Restart your computer after the first Oracle installation on Windows 98. Subsequent installations only require a shut down and restart if the Oracle home changes.


See Also:

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.


Note:

Do not delete or manually alter the Inventory directory or its contents. Doing so can prevent the Installer from locating products that you install on your system.

Deinstalling Oracle Components and Services

This section describes how to deinstall Oracle components, utilities, and services.


Note:

Deinstalling Oracle9i JVM causes Oracle Universal Installer to remove the database and other products dependent on Oracle9i JVM from your system.

This section contains these topics:

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 .

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

In rare situations, you may want to correct serious system problems by completely removing Oracle components from the computer.

Remove all Oracle components from your computer only as a last resort, and only if you want to remove all Oracle components from your system.

Oracle Universal Installer does not delete services created by Oracle Net Configuration Assistant, OiD Configuration Assistant, and Database Configuration Assistant. In addition, several other registry keys are not deleted.


Note:

You can also use the ORADIM utility to manually deinstall an instance and services. See "Postinstallation Database Creation" of Oracle9i Database Administrator's Guide for Windows.


Caution:

Use Microsoft Registry Editor at your own risk. Incorrect usage of Registry Editor can cause serious problems and may require reinstallation of your operating system.

To remove the Oracle Net Service registry entry on Windows NT, Windows 2000, and Windows XP:

  1. Log in as a member of the Administrators group.

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

  3. Start the registry at the MS-DOS command prompt:
