Installing Liberty interim fixes on IBM i operating systems using the command line

Interim fixes provide corrective service for specific known problems. You can use the IBM® Installation Manager command-line function to update the offering with the fixes that are available for your service level of WebSphere® Application Server Liberty for IBM i.

1. For a list of interim fixes that are available for WebSphere Application Server Liberty for IBM i and specific information about each interim fix, perform the following actions.
   1. Go to Fix Central.
   2. Click Find product.
   3. Select WebSphere Liberty as the product group.
   4. Select the version of the product to be updated.
   5. Select IBM i as the platform, and click Continue.
   6. Select Browse for fixes, and click Continue.
   7. Click More Information under each fix to view information about the fix.
2. Update WebSphere Application Server Liberty for IBM i with the interim fixes using one of the following procedures.
   • Access the live service repository that contains the fixes, and use web-based updating.
     Use Installation Manager on your local system to update WebSphere Application Server Liberty for IBM i with the interim fixes from the live web-based service repositories.

     • For the live service repositories, use the same URLs as those used for the generally available product-offering repositories during installation. These URLs are listed in Online product repositories for Liberty offerings.
     • These locations do not contain web pages that you can access using a web browser. They are remote web-based repository locations that you specify for Installation Manager so that it can maintain the offering.
     To install an interim fix from a service repository, perform the following actions:

     1. If you do not already have Installation Manager credential-storage and master-password files containing your IBM software user ID and password, create files that will allow you to access the repository.
        Note: These are the credentials that you use to access protected IBM software websites.
        Tip: 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 that is specified.
     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 Liberty for IBM i installation that is being updated.
     4. On a CL command line, run the STRQSH command to start the Qshell command shell.
     5. Make sure that the umask is set to 022.
        To verify the umask setting, issue the following command:

        umask

        To set the umask setting to 022, issue the following command:

        umask 022

     6. Change to the Installation_Manager_binaries/eclipse/tools directory, where Installation_Manager_binaries is the installation root directory for the Installation Manager.

        On IBM i systems, the root directory for the Installation Manager is /QIBM/ProdData/InstallationManager.

     7. Install the interim fix.

        ./imcl install interim_fix_name
          -installationDirectory offering_installation_location
          -repositories repository_URL_or_path
