Installing Liberty on z/OS

You can install the Liberty offerings by using IBM® Installation Manager Version 1.8.5 or later. Installation Manager installs offerings from one or more product repositories.

About this task

[16.0.0.4 and later]Note: Support for using Java™ SE 6 with WebSphere® Liberty ends in September 2017. After the end of support, the Liberty kernel will be recompiled and can no longer run with Java SE 6. If you continue to use Java SE 6 on earlier fix packs after the end of support date, you could expose your environment to security risks.

Java SE 8 is the recommended Java SDK because it provides the latest features and security updates. You can install it by installing the IBM SDK, Java Technology Edition, Version 8 package to the package group that contains WebSphere Liberty.

Procedure

  1. Create an Installation Manager.
  2. Access the product repositories.

    Perform the following procedure: Accessing product repositories on z/OS.

  3. Optional: Configure an instance of the Liberty Asset Repository Service or a local directory-based repository.
    As part of installing Liberty, you can choose to install assets from the following repositories:
    • The Liberty Repository, a public IBM-hosted repository that is accessible through the internet. For more information, see Liberty: Liberty Repository.
    • The Liberty Asset Repository Service, an open source service that you can use to create an on-premises repository that is remotely accessible behind the firewall of an enterprise. For more information, see the WASdev/tool.lars project on GitHub.
    • Local directory-based repositories, which you create by using the installUtility download action or by downloading the wlp-featureRepo-<version>.zip file, which contains all applicable features and addons. For more information, see Downloading assets using the installUtility command.

    Access to the Liberty Repository requires internet access. If your system does not have internet access or you want to install customized Liberty assets, set up an instance of the Liberty Asset Repository Service or a local directory-based repository, and then add the repository URL, directory path, or archive path in Installation Manager. For more information about the Liberty repositories, see Installing assets using Installation Manager.

  4. Install WebSphere Application Server for z/OS Liberty.

    Perform the following procedure: Installing WebSphere Application Server for z/OS Liberty.
