Deinstallation and Reinstallation

This chapter guides you through the deinstallation and reinstallation process for Oracle9i Application Server (Oracle9iAS). The topics include:

• Deinstallation

• Reinstallation

8.1 Deinstallation

The following steps guide you through the deinstallation process of Oracle9iAS.

In order to successfully deinstall Oracle9iAS from your host, Oracle recommends deinstalling all secondary (or subsequent) Oracle9iAS installations before you deinstall the primary (or first) installation.

Note: Stop all services and processes before starting the deinstallation process.

Note: Oracle Universal Installer does not permit custom deinstallation of select components or Oracle9iAS instances. Confirm deinstall objectives before launching deinstallation.

8.1.1 Deinstalling Using Oracle Universal Installer

1. Start the Oracle Universal Installer.

   Once Oracle Universal Installer is launched, the Welcome screen appears. Click Deinstall Products.

   The Welcome screen provides information about Oracle Universal Installer.

   The installer provides you with two ways to deinstall products:

   • Deinstall Products: Deinstalls the entire product.

   • Installed Products: View currently installed products and deinstall the entire product.

   The Inventory screen appears when you click Deinstall Products on the Welcome screen, or Installed Products on any screen.

   The Inventory screen displays all the components installed in Oracle home.

   The following buttons and product information appear on the Inventory screen:

   • Remove: Deinstall all checked components from Oracle home.

   • Save As: Save the inventory as text. A file browser dialog pops up when you click Save As. Accept a file name and the complete inventory list as displayed by the inventory screen will be logged into this file as text.

   The following buttons appear on the Confirmation screen:

   • Help: Access detailed information about the functionality of the Confirmation screen.

   • Yes: Start deinstallation of listed components.

   • No: Return to the Inventory screen. Listed components are not removed from Oracle home.

   Text description of the illustration adminserv.gif

   This screen presents one of the following messages:

   • The active Oracle9iAS Administration Service is in /private/OraHome1. There are no other Administration Services available.

     This message appears when there is only one Oracle9iAS installation on the host and you are about to deinstall it.

   • The active Oracle9iAS Administration Service is in /private/OraHome1. You may select one of the Administration Services below to become the active one.

     This message appears when there are multiple Oracle9iAS installations on the host and you are about to deinstall the primary installation. You must select one of the remaining Oracle9iAS installations which will then become the primary installation and the new location for the Oracle9iAS Administration Service.

5. Monitor the deinstallation process.

   The Remove Progress Bar screen appears when you click Remove. The installer detects all components chosen for deinstallation from the Inventory screen and removes them from Oracle home.

   • Cancel: To discontinue the deinstallation process.

     Note: If you deinstall a product or component, then all of its dependent components and files will also be deinstalled.

   You have successfully deinstalled Oracle9iAS.

8.2 Reinstallation

Oracle Universal Installer does not allow reinstallation of Oracle9iAS over an installed version. To reinstall Oracle9iAS over the same version, deinstall and then install the product.
