Manual Software Update Uninstallation Procedure

Manual uninstallation of a Software Update package can be used to uninstall the latest Software Update package regardless of whether the installation was done manually or by using the Software Update System. This must be performed at the node that requires the uninstall; that is, uninstallation is done on a node by node basis. Only the latest Software Update package can be uninstalled.

To uninstall Software Update packages manually:

  1. In the product-directory\updates\backup folder on the node that requires Software Update uninstallation, find the name of the uninstaller package file related to the latest update level. Each jar file is an uninstaller package. The uninstaller has the format <system-name>_<update-level>_uninstaller.jar. For example <system-name>_0005_uninstaller.jar indicates this is the uninstaller package for update level 0005.

  2. Open a DPX command prompt on Windows or a command shell on UNIX or Linux. See the Procedure for Opening a Command Prompt.

  3. On that node, set the proper environmental variable PATH for accessing "java" command or, in Step 4 below, specify the path to the java runtime environment (JRE). You must use the JRE provided at location product-directory\tools\jre on your node. Manual software update uninstallation requires JRE version 1.6 and above.

  4. Run the following command (on a single line): product_directory\tools\jre\bin\java -jar <uninstaller_package_name>.jar

  5. Follow the instructions displayed by the uninstaller to complete the uninstallation.

After completion of uninstalling the latest update package, the update level will be the level prior to the installation of the update package that you have just uninstalled.

Note. In the file .swinfo in the DPX Product Directory, the "version" value might not revert. If so, it should be changed manually by using a privileged command prompt.
