Installing Open Liberty

Open Liberty is required on all workstations where you plan to install the server components and the Dynamic Workload Console.

Before you begin

This picture describes the steps required for installing the full HCL Workload Automation software stack. You are now at step 1: installing Open Liberty
Ensure that your system meets the operating system and Java requirements. For more information, see Open Liberty detailed system requirements.

About this task

You can quickly install or upgrade Open Liberty or WebSphere Application Server Liberty Base by extracting a file on all supported platforms.

If you already have WebSphere Application Server Liberty Base installed, you can use it with HCL Workload Automation, otherwise you can install Open Liberty, as described below.

If you want to move from WebSphere Application Server Liberty Base to Open Liberty, see Moving from WebSphere Application Server Liberty Base to Open Liberty.

Install Open Liberty or WebSphere Application Server Liberty Base on all of the following workstations, which comprise a typical installation:
  • master domain manager (distributed environments only)
  • backup domain manager (distributed environments only)
  • two Dynamic Workload Console installations on two separate workstations (distributed and z/OS environments)

If you plan to install a dynamic domain manager and its backup, these components require a separate application server.

On UNIX workstations, you can install Open Liberty using a user of your choice. In this case, assign the HCL Workload Automation administrative user read and write access to the Open Liberty installation directory.

Procedure

  1. Find out which version of WebSphere Application Server Liberty Base is required, by checking the required version of the Application server in Related Software Report.
  2. Download WebSphere Application Server Liberty Base from Recommended updates for WebSphere Application Server Liberty.
  3. Install WebSphere Application Server Liberty Base by extracting the archive file to a directory of your choice.
    On Windows operating systems
    java -jar <liberty_download_dir>\wlp-base-all-<version>.jar --acceptLicense <install_dir>
    On UNIX operating systems
    ./java -jar <liberty_download_dir>/wlp-base-all-<version>.jar --acceptLicense <install_dir>
    where:
    <liberty_download_dir>
    The directory where you downloaded WebSphere Application Server Liberty Base.
    <version>
    The number of the version.
    <install_dir>
    The directory where you want to install WebSphere Application Server Liberty Base.
    Note: Note that the value of the <install_dir> parameter must match the value to be defined for the wlpdir parameter when installing the master domain manager and its backup, dynamic domain manager and its backup, and the Dynamic Workload Console.
  4. Ensure the HCL Workload Automation administrative user has the rights to run WebSphere Application Server Liberty Base and full access to the installation directory. If WebSphere Application Server Liberty Base is shared between the master domain manager and the Dynamic Workload Console, ensure also the Dynamic Workload Console user has the same rights.

Results

You have now successfully installed the application server.
