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 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.

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

Download Open Liberty from Get started with Open Liberty.

Check the release notes or the latest readme to ensure the latest Open Liberty version is supported by HCL Workload Automation. You can find the Release Notes at Product Requirements, while the link to the latest readme is available in ../../distr_readmes.html.
Install Open Liberty by extracting the archive file to a directory of your choice.
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 
```
where:

openliberty_download_dir

The directory where you downloaded Open Liberty.

install_dir

The directory where you want to install Open Liberty.
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.
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.

What to do next

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