Uninstalling fix packs from IBM i operating systems using response files

You can roll back this product to an earlier version using Installation Manager response files.

Before you begin

During the rollback process, Installation Manager must access files from the earlier version of the package. By default, these files are stored on your computer when you install a package. If you change the default setting or delete the saved files, Installation Manager requires access to the repository that was used to install the earlier version.

Restriction: You cannot use the Installation Manager to roll back an installation and add or remove the full WebSphere® Application Server profile feature or the Liberty profile feature.

Procedure

  1. Optional: If the repository requires a username and password, create a keyring file to access this repository.

    For more information on creating a keyring file for Installation Manager, read the IBM® Installation Manager Version 1.6 Information Center or the IBM Installation Manager Version 1.5 Information Center.

    Tip: When creating a keyring file, append /repository.config at the end of the repository URL location if the imutilsc command is unable to find the URL that is specified.
    Note: Starting in Installation Manager Version 1.6.2, the -keyring and -password options that have been used to access credentials in a keyring file are deprecated. When you use Installation Manager Version 1.6.2 and later, use the -secureStorageFile and -masterPasswordFile options to store credentials in a credential storage file.

    There is no migration path from keyring files to storage files because of the differences in the file structures. You must create a storage file to replace a keyring file.

    For more information on using the -secureStorageFile and -masterPasswordFile options to store credentials in a credential storage file, see the Installation Manager Version 1.6 Information Center.

  2. Sign on to the IBM i system with a user profile that has *ALLOBJ and *SECADM special authorities.
  3. Stop all servers and applications on the WebSphere Application Server installation that is being rolled back.
  4. On a CL command line, run the STRQSH command to start the Qshell command shell.
  5. Use a response file to roll back the product.
    Change to the eclipse/tools subdirectory in the directory where you installed Installation Manager, and roll back the product. For example:
    ./imcl
      input $HOME/WASFiles/temp/rollback_response_file.xml 
      -log $HOME/WASFiles/temp/rollback_log.xml 
      -keyring $HOME/WASFiles/temp/im.keyring
    Note: The program might write important post-installation instructions to standard output.

    For more information on using Installation Manager, read the IBM Installation Manager Version 1.6 Information Center or the IBM Installation Manager Version 1.5 Information Center.

  6. Optional: List all installed packages to verify the roll back.
    ./imcl listInstalledPackages -long

Example

The following is an example of a response file for rolling back the product to an earlier version.
<?xml version="1.0" encoding="UTF-8"?>
<agent-input>
<server>
  <repository location='https://www.ibm.com/software/repositorymanager/com.ibm.websphere.EXPRESS.v85'/>
</server>
<profile id='IBM WebSphere Application Server V8.5' installLocation='/QIBM/ProdData/WebSphere/AppServer/V85/EXPRESS'>
  <data key='eclipseLocation' value=''/QIBM/ProdData/InstallationManager'/>
</profile>
<rollback>
  <offering profile='IBM WebSphere Application Server V8.5' id='com.ibm.websphere.EXPRESS.v85' version='8.5.0.20101025_2108'/>
</rollback>
</agent-input>
Tips:
  • The profile ID (<profile . . . id='profile_ID' . . . .> and <offering . . . profile='profile_ID' . . . .>) can be found when you run the imcl listInstallationDirectories -verbose command from the eclipse/tools subdirectory in the directory where you installed Installation Manager. It is the same as the package group’s name.
  • The offering ID (<offering . . . id='offering_ID' . . . .>) can be found in the Install Manager Offering ID section of the report that is generated when you run the historyInfo or genHistoryReport command from the app_server_root/bin directory.
  • The version is a specific version of the offering to which to roll back (8.5.0.20101025_2108 for example).
    This specification is optional if you are using Installation Manager Version 1.5 or later.
    • If version is not specified, the installation rolls back to the previously installed version of the offering and all interim fixes for that version are installed.
    • If version is specified, the installation rolls back to the specified earlier version of the offering and no interim fixes for that version are installed.

    The offering version can be found attached to the end of the offering ID with an underscore in the Package section of the report that is generated when you run the historyInfo or genHistoryReport command from the app_server_root/bin directory.
