### Deinstalling Oracle Procedural Gateway for WebSphere MQ

   The Welcome screen provides information about Oracle Universal Installer.

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

   - Deinstall Products: Deinstall individual components, or the entire product.

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

2. Review all installed components, and select the ones you want to deinstall. 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: Deinstall 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 deinstall Oracle Procedural Gateway for WebSphere MQ completely, select the box displayed before the product name. It is listed directly below the `ORACLE_HOME` name.

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

   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 deinstallation of listed components.

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

4. Monitor the deinstallation 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.
