This chapter guides you through the uninstallation and reinstallation options for Oracle Database Gateway for WebSphere MQ. It contains the following sections:

6.1 Removing the Gateway

To remove Oracle Database Gateway for WebSphere MQ perform the following steps:

  1. Start the Oracle Universal Installer. For information about starting the installer, refer to Starting Oracle Universal Installer.

    When Oracle Universal Installer starts, the Welcome screen is displayed. Click Deinstall Products.

    The Welcome screen provides information about Oracle Universal Installer.

    Oracle Universal Installer provides you with two ways to uninstall products:

    • Deinstall Products: Uninstall individual components, or the entire product.

    • Installed Products: View currently installed products, and uninstall individual components or the entire product.

  2. Review all installed components, and select the ones you want to uninstall. Click Remove.

    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 that are installed in the Oracle home directory.

    The following buttons appear on the Inventory screen:

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

    • Remove: Uninstall all checked components from the Oracle home directory.

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

    • Close: Quit the Inventory screen.

    • Location: View the full location path of the selected component.

      Note:

      The plus sign (+) sign before a product name indicates that there are more components and files installed within that particular product. Click it to view dependent components. If you choose to remove a product or component, then all of its dependent components and files are also deinstalled.

    If you want to remove the Oracle Database Gateway for WebSphere MQ completely, select the box displayed before the product name. It is listed subsequent to the ORACLE_HOME name.

    Note:

    If you deinstall a product or component, then all of its dependent components and files are also deinstalled.
  3. Verify the components selected for uninstallation, and click Yes.

    The Confirmation screen lists all the components selected for deinstallation in the previous step. Scroll down the screen to verify selected components.

    The following buttons appear on the Confirmation screen:

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

    • Yes: Start uninstallation of listed components.

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

  4. Monitor the uninstallation process.

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

    • Cancel: To discontinue the deinstallation process.

      Note:

      If you deinstall a product or component, then all of its dependent components and files are also deinstalled.
