Uninstall Liberty fix packs from distributed operating systems using the command line

We can roll back WebSphere Application Server Liberty Core to an earlier version using the Installation Manager command line.

Restriction: To use this procedure, have Installation Manager Version 1.6 or later installed on the system.

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

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

   When creating a credential-storage file, append /repository.config at the end of the repository URL location if the imutilsc command is unable to find the URL specified.

   When we use Installation Manager v1.6.2 and later, we should use the -secureStorageFile and -masterPasswordFile options to store credentials in a credential-storage file. In versions of Installation Manager earlier than v1.6.2, the -keyring and -password options were used to access credentials in a keyring file. These options were deprecated in v1.6.2. There is no migration path from keyring files to storage files because of the differences in the file structures. 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. For more information on using the -keyring and -password options to store credentials in a keyring file, see the Installation Manager Version 1.5 Information Center.

2. Log on to the system.

3. Stop all servers and applications on the installation that is being rolled back.

4. Change to the eclipse/tools subdirectory in the directory where you installed Installation Manager.

5. 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
     -secureStorageFile storage_file -masterPasswordFile master_password_file
     -acceptLicense

   

   imcl.exe rollback offering_ID_offering_version
     -repositories source_repository 
     -installationDirectory installation_directory
     -preferences preference_key=value
     -properties property_key=value
     -secureStorageFile storage_file -masterPasswordFile master_password_file
     -acceptLicense

   Tips:

   Server product offerings for supported operating systems.
   • 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 (8.5.5.20110503_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.

   • If we are rolling back from v8.5.5.4 to v8.5.5.3 and we have the Extended Programming Models installed, we might receive errors. To prevent errors, specify a properties parameter,addon=""; for example:

     ./imcl rollback offering_ID_offering_version
       -repositories source_repository 
       -installationDirectory installation_directory
       -preferences preference_key=value
       -properties user.accept.license=true,user.addon=""
       -secureStorageFile storage_file -masterPasswordFile master_password_file
       -acceptLicense

     

     imcl.exe rollback offering_ID_offering_version
       -repositories source_repository 
       -installationDirectory installation_directory
       -preferences preference_key=value
       -properties user.accept.license=true,user.addon=""
       -secureStorageFile storage_file -masterPasswordFile master_password_file
       -acceptLicense

   For more information on using Installation Manager, read the IBM Installation Manager Information Center.

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

   

   imcl.exe listInstalledPackages -long
