Reverting to a previous installation configuration

As you install, upgrade, and uninstall software in z/OS® Explorer, configuration snapshots are kept in a history. You can revert to a previous configuration to back out the results of an unsuccessful installation, upgrade, or uninstall. You can also revert z/OS Explorer to a previous version. However, you must have access to an update site because when you upgrade the z/OS Explorer product, previous versions are not saved.

If you used IBM® Installation Manager to install, upgrade, or uninstall software in z/OS Explorer, you can revert to a previous version by using the rollback feature, and you do not need to use the following procedure.

Important: It is a limitation of Eclipse that before you can revert to a previous version of z/OS Explorer, you must have access to an update site that includes the required version.
To download the update site, use the following steps:
  1. For the Product Group field, select Other Software and for Product, select IBM Explorer for z/OS. For the Installed Version and Platform fields, select All, then click Continue.
  2. Select Browse for fixes and click Continue.
  3. Select the update site at the level you want to revert to and click Continue.
  4. Download the update site to your workstation. Do not uncompress the file. z/OS Explorer requires a compressed file.
  5. In z/OS Explorer, add the update site by using Help > Software Updates on the workbench menu. For more information, see Adding a new software update site.
You can now revert z/OS Explorer to the required level.

This example task shows you how to revert z/OS Explorer to a previous configuration.

  1. Click Help > Install New Software on the workbench menu.
    The Install window opens.
  2. Click the What is already installed link.
    The Installation Details window opens. The Installation History tab shows a list of the previous configurations.
  3. Select the configuration that you want to revert to. When you select a configuration, another pane shows the content in that configuration.
    Attention: The oldest entry in the list of previous configurations represents the initial z/OS Explorer installation. This configuration has no contents. Do not revert to this configuration. If you do, z/OS Explorer fails and must be completely reinstalled.
  4. Click Revert. The Revert Software Configuration confirmation dialog is displayed.
  5. Click Yes to confirm, and when asked to exit and restart the workbench for the changes to take effect.
z/OS Explorer reverts to the selected configuration and restarts.
