Uninstalling fix packs using the command line

You can roll back this product to an earlier version using IBM® Installation Manager from the command line.

Before you begin

Restriction: In order to use this procedure, you must have Installation Manager Version 1.5 or later installed on your system.

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.

About this task

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

Optional: If the repository requires a user name 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 1.5 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.
Log on to your system.
Stop all processes that are running in your environment.
- To stop all processes that are running in your stand-alone eXtreme Scale environment, see Stopping stand-alone servers that use the ORB transport.
- To stop all processes that are running in your WebSphere Application Server environment, see Command-line utilities.
Change to the eclipse/tools subdirectory in the directory where you installed Installation Manager.
Use the imcl command to roll back the product.
```
./imcl rollback offering_ID_offering_version
  -repositories source_repository 
  -installationDirectory installation_directory
  -preferences preference_key=value
  -properties property_key=value
  -keyring keyring_file -password password
  -acceptLicense
```
```
imcl.exe rollback offering_ID_offering_version
  -repositories source_repository 
  -installationDirectory installation_directory
  -preferences preference_key=value
  -properties property_key=value
  -keyring keyring_file -password password
  -acceptLicense
```
Tips:
- The offering_ID is the offering ID that is listed in Offering IDs for WebSphere eXtreme Scale product offerings.
- The offering_version, which optionally can be attached to the offering ID with an underscore, is a specific version of the offering to which to roll back (8.5.0.20110503_0200 for example).
  - If offering_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 offering_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.
For more information on using Installation Manager, read the IBM Installation Manager documentation.

Optional: List all installed packages to verify the roll back.
