# About the Uninstallation Program

The following sections describe how to uninstall WebLogic Platform on Windows and UNIX systems. You can uninstall WebLogic Platform using graphical mode or console mode, or silent mode. To run the graphical mode uninstallation program, your console must support a Java-based GUI. If the uninstallation program determines that your system cannot support a Java-based GUI, it automatically starts running in console mode.

You can uninstall individual components of WebLogic Platform, or the entire installation. Dependency checking in the uninstaller ensures that the appropriate components are uninstalled.

Uninstalling WebLogic Platform does not remove the BEA Home directory associated with the installation, the SDK, or any user-created domains. Only the components that were installed by the installation program can be removed. If you choose to uninstall the entire WebLogic Platform installation, the uninstallation program also removes the WebLogic Platform product directory associated with the installation unless one of the following is true:

- The product directory contains customer-created configuration or application files—the uninstallation program does not delete customer-created configuration or application files or domains.
- The complete installation was not uninstalled. If an individual component is uninstalled, only the installation directory for that component is removed; the installation directories for other components are unaffected.
- The uninstall was invoked from within the product directory structure—specifically, within the `uninstaller` directory.

## Uninstalling Service Packs and Rolling Patches

If you have installed a service pack or rolling patch, you can revert your system installation to an earlier version of the release as follows:

- You can revert to the prior service pack installation on your system. For example, if you first install WebLogic Platform 8.1 Service Pack 4 (SP4), and then install Service Pack 5, you can later revert to WebLogic Platform 8.1 SP4.

Note: If you revert to an earlier service pack, user-created domains may not work with the earlier service pack because of changes made in the `config.xml` file between service packs. If you made backup copies of the `config.xml` files in the earlier service pack, you should use them after you revert the installation.

- You can revert a rolling patch upgrade to the service pack on which the rolling patch is based. (Rolling patches are cumulative: each rolling patch replaces all earlier rolling patches on a particular service pack base.) For example, if you first install WebLogic Platform 8.1 SP2, and then install rolling patches 1 and 2 (RP1 and RP2), you can later revert to WebLogic Platform 8.1 SP2. You cannot revert to an earlier rolling patch, however.

Note: If you install additional WebLogic Platform components after installing a service pack or rolling patch, you cannot roll back to any previous versions of the product.

To revert to a previously installed version of WebLogic Platform, you can use the uninstallation program or Smart Update. See Uninstalling Maintenance Upgrades Using Smart Update for instructions on using Smart Update to roll back to a previous installation.

# Uninstalling WebLogic Platform in Silent Mode

When you uninstall WebLogic Platform in silent mode, the full installation of WebLogic Platform is uninstalled. You cannot use silent-mode uninstallation to roll back to a previous service pack or to uninstall individual WebLogic Platform components.

When you run the uninstallation program in silent mode, it leaves behind the same files and directories as when you run the uninstallation program in GUI and console modes, including:

- The BEA Home directory, including the `logs` and `utils` subdirectories
- The Java 2 SDK, if it was installed with WebLogic Platform
- Domain directories, including those in `user_projects`
- Any other file created or modified after WebLogic Platform was installed

You can manually delete these files.

Although you can use silent-mode uninstallation to manually uninstall WebLogic Platform, silent-mode uninstall is intended for use in scripts. You can adapt the steps in Table 8-3 for use in scripts.

Use the following procedure to uninstall WebLogic Platform in silent mode:

1. Shut down any servers that are running. If you configured any of the servers as a Windows service, you must stop the service(s) before uninstalling the software.
2. Start the uninstallation program as described in Table 8-3.

# Reinstalling WebLogic Platform

You cannot reinstall the same version of WebLogic Platform or any of its components over a previous WebLogic Platform installation of the same components—in the same BEA Home directory or in the same file location. You can, however, add components to an existing installation. For example, you can install WebLogic Server during one installation, and WebLogic Integration or WebLogic Portal during a separate installation.

To reinstall the same version of one of the product components or the entire WebLogic Platform distribution in the same location, you must first uninstall the previous installation.

If you try to install a copy of WebLogic Platform 8.1 in a BEA Home directory that already contains an 8.1 installation, the installation program displays an error message. An example of the error messages displayed is shown in the following table.

If you try to install . . . | In a directory that contains . . . | The following error message is displayed . . .
8.1 SP5 | 8.1 SP5 | `A complete installation of WebLogic Platform 8.1 SP5 exists in this BEA Home. Please select another BEA Home or uninstall the product.`
8.1 SP5 | 8.1 SP4 | `The product maintenance level of the current installer (8.1.5.0) is not compatible with the maintenance level of the product installed on your system (8.1.4.0). Please obtain a compatible installer or perform maintenance on your current system to achieve the desired level.`

Click or type `OK` to return to the Choose BEA Home directory prompt.

At the prompt, choose one of the following options:

- To continue installing the software using a different BEA Home directory, select an existing BEA Home directory that does not contain a WebLogic Platform installation or create a new BEA Home directory.
- Exit the installation program. If you want to reinstall WebLogic Platform 8.1 in the same BEA Home, you must uninstall the previous installation. You can invoke the uninstall program appropriate for your platform, as described in one of the following sections:

- Uninstalling WebLogic Platform in Graphical Mode
- Uninstalling WebLogic Platform in Console Mode

Then reinstall the software as described in one of the following sections:

- Installing WebLogic Platform Using Graphical-Mode Installation
- Installing WebLogic Platform Using Console-Mode Installation
- Installing WebLogic Platform Using Silent-Mode Installation
