Installing Open Liberty

Open Liberty is required on all workstations where you plan to install the server components and the Dynamic Workload Console.This picture describes the steps required for installing the full HCL Workload Automation software stack. You are now at step 1: installing Open Liberty

Before you begin

On AIX and Linux workstations, ensure you permanently set the ulimit parameter as follows:
  • data segment process (option -d) = unlimited
  • file size (option -f) = unlimited
  • max user processes (option -u) = >260000 up to unlimited
  • open files (option -n) = >100000 up to unlimited
  • max memory size (option -m) = unlimited
  • stack size (option -s) = >33000 up to unlimited
On the master domain manager, these settings must be applied to:
  • root
  • the HCL Workload Automation administrative user
On the Dynamic Workload Console, these settings must be applied to:
  • root
  • the Dynamic Workload Console installation user (if this user is different from root)
Ensure that your system meets the operating systemrequirements. For more information, see Open Liberty detailed system requirements.

About this task

You can quickly install Open Liberty by extracting an archive 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 on all of the following workstations, which comprise a typical installation:
  • master domain manager
  • backup domain manager
  • two Dynamic Workload Console installations on two separate workstations

If you plan to install a dynamic domain manager and its backup, these components require a separate Open Liberty installation.

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.

To install Open Liberty, perform the following steps:

Procedure

  1. Download Open Liberty from Get started with Open Liberty.

    Check the required version of the Application server in the Supported Software document available in Product Requirements. Download the package named All GA Features for the required version.

  2. Perform one of the following actions:
    1. Extract Open Liberty using the root user:
      On Windows operating systems
      unzip <openliberty_download_dir>\openliberty-<version>.zip
 -d <install_dir>
--acceptLicense
      On UNIX operating systems
      unzip <openliberty_download_dir>/openliberty-<version>.zip
 -d <install_dir>
--acceptLicense
    2. Run the following command to assign permissions:
      chmod 755 -R "wlp_directory"

    OR

    Extract Open Liberty using the user who is going to install the product, as follows:
    su - "wauser"
unzip
    where:
    <openliberty_download_dir>
    The directory where you downloaded Open Liberty.
    install_dir
    The directory where you want to install Open Liberty.
    Note: Install the new Open Liberty in the exact location of the previous WebSphere Application Server Liberty Base installation.
  3. Ensure the HCL Workload Automation administrative user has the rights to run Open Liberty and full access to the installation directory. If Open Liberty 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 Open Liberty.
