Uninstalling service for runtime components

On some platforms, you can remove fixes that you have applied.

Start of change
Distributed systems
You cannot remove individual fixes that you have applied to runtime components on distributed systems. If you want to restore a system to a previous service level, you must uninstall the product before you reinstall the desired level of service.

If you have a single installation on your computer, create and retain a backup image, or keep previous GA or fix pack images or media, in case of problems after you have installed service. If you have multiple installations, each one can be at a different service level and you can transfer the runtime components to work with an alternative installation at a newer or older level of service. This option is described in Applying service to runtime components.

When you uninstall the product, the components that you have created are not lost, and you can continue to use these components and associated resources with the reinstalled product. However, you might want to take a backup of the installation and work path directories before you start this procedure.

To restore a system on which you have a single installation to a previous service level:

  1. Uninstall the entire product.
  2. Reinstall the GA level of the product. This step is required to ensure that you comply with your license agreement.
  3. Install the desired level of fix pack.
z/OS
On z/OS systems, you can uninstall service levels under some circumstances during the installation phase; for further information, see Installing service on z/OS.
