Uninstalling a Delta Patch but Retaining Previous Releases

As part of testing or troubleshooting, sometimes you might want to uninstall a single Siebel Innovation Pack release or Siebel Patchset release, while leaving the prior installed release or releases intact. For example, you might want to remove version 17.0, but retain version 8.1.1 and version 8.1.1.7, or retain version 8.2.2 and version 8.2.2.2. You can use the procedure in this topic to uninstall a corresponding delta patch.
Note: Using this method, you can uninstall only a delta patch, not any other type of patch release. A delta patch is software that was installed using a Siebel Anywhere upgrade kit of type Siebel Client Executables with Select Type of Installation set to Delta Install. For more information, see Roadmap for Creating a Delta Installation Siebel Client Executables Upgrade Kit.

The following procedure describes how to uninstall a delta patch.

To remove a delta patch but retain the prior installed release or releases

  1. Navigate to the existing root directory of the client installation (SIEBEL_CLIENT_INSTALL), such as C:\Siebel\Client.

  2. Locate the following directories, which were created when the delta patch was installed:

    • PATCHBACKUP_BASE. This folder is for the base portion of the installation that was performed through the delta patch.

    • PATCHBACKUP_language-code, where language-code is the code for each language that is used in the client installation. For example, the directory might be called PATCHBACKUP_ENU for U.S. English. This folder is for a language-specific portion of the installation that was performed through the delta patch.

    • PATCHBACKUP_language-code, where language-code is the code for each language that is used in the client installation. SIA applies for all Siebel Industry Applications. For example, the directory might be called PATCHBACKUP_ENUSIA for U.S. English. This folder is for a language-specific portion of the installation that was performed through the delta patch.

    • PATCHBACKUP_. This folder is for the base portion of the installation, plus all language-specific portions of the installation, that was performed through the delta patch.

  3. In each of the directories that you located rename the file unpatch.bak to unpatch.bat.

  4. In each of these directories, execute unpatch.bat.
    Note: The unpatch.bat files can be executed from the various directories in any order.
