Installing WebSphere Application Server Liberty

Installing WebSphere Application Server Liberty to the latest supported version. This is an optional step you might want to perform before you upgrade the Dynamic Workload Console and the server components.

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 system and Java requirements. For more information, see WebSphere Application Server Liberty detailed system requirements.

About this task

You can quickly install WebSphere Application Server Liberty Base by extracting an archive file on all supported platforms.

Install WebSphere Application Server Liberty Base 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 WebSphere Application Server Liberty Base installation.

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

To extract the archive, you can use your own Java Ext or use the Java Ext provided with the HCL Workload Automation image. The provided Java Ext is located in the following path in the image for your operating system: IMAGE_DIR/TWS/INTERP/Tivoli_Eclipse_INTERP/TWS/JavaExt/.

To install WebSphere Application Server Liberty Base, perform the following steps:

Procedure

  1. Download WebSphere Application Server Liberty Base from Recommended updates for WebSphere Application Server Liberty.
    Each WebSphere Application Server Liberty Base image is packaged as a .jar file named wlp-base-all-fix_pack.jar.

    Check the release notes to ensure the latest WebSphere Application Server Liberty Base version is supported by HCL Workload Automation. You can find the Release Notes at Product Requirements,.

  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 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 WebSphere Application Server Liberty Base.

What to do next

You can now proceed to Encrypting passwords (optional) or to Creating and populating the database for the Dynamic Workload Console.
