Uninstalling WebLogic Server
The following sections provide platform-specific procedures for uninstalling WebLogic Server:
About the Uninstallation Program
On both Windows and UNIX systems, you can uninstall WebLogic Server using either graphical mode or console 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, the uninstallation program automatically starts in console mode.
You can uninstall WebLogic Server examples only, or the entire WebLogic Server installation. When you uninstall the entire WebLogic Server installation, the uninstaller also uninstalls the WebLogic Node Manager Windows service, if it was installed as a Windows service (Windows platforms only).
Uninstalling WebLogic Server does not remove the BEA Home directory associated with the installation, or the JVM. If you choose to uninstall the entire WebLogic Server installation, the uninstallation program also removes the WebLogic Server 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.
If you have installed a service pack or rolling patch, you can also use the uninstallation program to revert to a prior service pack. See Uninstalling WebLogic Server in Graphical Mode.
Uninstalling WebLogic Server in Graphical Mode
Use the following procedure to uninstall WebLogic Server or WebLogic Server examples using the graphical interface:
- Shut down any servers that are running. If you configured any of the servers as a Windows service, you should stop the service(s) before uninstalling the software.
- Start the uninstallation program as described in the Table 8-1:

<------------- Weblogic Platform Uninstaller -------------->
Choose Components:
Release 8.1
+----WebLogic Server [0] v
+----Server [0.0] v
+----Server Examples [0.1] v
Enter number exactly as it appears in brackets to toggle
selection OR [Exit][Previous][Next]> next
By default, all installed components are selected, indicating that they will be removed.
To leave a component installed on your system, type the numeric code for the option on the command line exactly as it appears within the brackets. For example, type 0.0 to deselect the Server and keep it installed on your system.
Dependency checking in the uninstallation program verifies that if you select a component to uninstall, all other components that are dependent on the selected component are also selected for uninstallation. For example, if you choose to uninstall the Server component, the uninstaller also uninstalls the Workshop and Server Examples components.
- Press Enter or type next.
You are prompted to confirm your selections, as shown in the following text:
Choose Components:
->1¦ Yes, uninstall these component selections
2¦ No, return to component selection
Enter index number to select OR [Exit][Previous][Next]>
- Press Enter or type next to proceed with the uninstallation process.
- When the uninstallation process is complete, press Enter or type done to complete the uninstallation and exit the uninstallation program.
Uninstalling Service Packs and Rolling Patches with the Uninstallation Program
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 installed WebLogic Server 8.1, then installed Service Pack 1 (SP1), you can revert to WebLogic Server 8.1. If you have WebLogic Server 8.1 SP1 installed on your system and you upgrade to WebLogic Server 8.1 SP2 (when available), you can revert only to WebLogic Server 8.1 SP1, you cannot revert to WebLogic Server 8.1.
- You can revert rolling patch upgrades to the prior 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 installed WebLogic Server 8.1 SP1, then installed rolling patches 1 and 2 (RP1 and RP2), you can revert to WebLogic Server 8.1 SP1. You cannot revert to an earlier rolling patch.
For instructions, see Uninstalling a WebLogic Server Service Pack or Rolling Patch in Graphical Mode or Uninstalling a WebLogic Server Service Pack or Rolling Patch in Console Mode.
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 Server, you can use the uninstallation program or Smart Update. See Uninstalling a Service Pack or Rolling Patch with Smart Update for instructions to use Smart Update to roll back to a previous installation.

Uninstalling a Service Pack or Rolling Patch with Smart Update
You can use Smart Update to 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 installed WebLogic Server 8.1, then installed Service Pack 1 (SP1), you can revert to WebLogic Server 8.1. If you have WebLogic Server 8.1 SP1 installed on your system and you upgrade to WebLogic Server 8.1 SP2 (when available), you can revert only to WebLogic Server 8.1 SP1, you cannot revert to WebLogic Server 8.1.
- You can revert rolling patch upgrades to the prior 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 installed WebLogic Server 8.1 SP1, then installed rolling patches 1 and 2 (RP1 and RP2), you can revert to WebLogic Server 8.1 SP1. You cannot revert to an earlier rolling patch.
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.
You can also uninstall a service pack or rolling patch using the standard uninstallation process. For more information, see Uninstalling WebLogic Server in Graphical Mode.
To uninstall a service pack or rolling patch, follow these instructions:
- Start Smart Update as described in Table 6-1.
- In the left pane, select the release for the product you want to roll back.
Service packs and rolling patches that you can uninstall (or roll back) are displayed in the Downgrade Options section of the window.
- In the Downgrade Options pane, select the service pack or rolling patch to uninstall and click OK.
The BEA Uninstaller Program opens.
- Click Next to proceed.
A status window displays the progress of the uninstallation. A message is displayed when the rollback or uninstallation is complete.
- Click Done on the status window.
The Smart Update window is displayed.
Reinstalling WebLogic Server
In most cases, you cannot reinstall WebLogic Server or any of its components over a previous WebLogic Server 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 Server Examples or Workshop Examples during separate installations.
To reinstall the same version of one of the product components or the entire WebLogic Server distribution in the same location, you must first uninstall the previous installation.
If you attempt to install a copy of the same version of WebLogic Server in the same BEA Home, the installation program displays the following message:
A complete installation of WebLogic Platform 8.1 exists in this BEA
Home. Please select another BEA Home or uninstall the product.
Type or click OK to return to the Choose BEA Home directory 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 Server 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 you platform as described in one of the following sections:
Then reinstall the software as described in one of the following sections:
