Installing WebSphere Application Server Liberty Base

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)

This picture describes the steps required for installing the full HCL Workload Automation software stack. You are now at step 1: installing WebSphere Application Server Liberty Base

Ensure that your system meets the operating system and Java requirements. For more information, see WebSphere Application Server Liberty Base 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

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

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
```
Note: To update HCL Workload Automation to version 9.5 Fix Pack 6, the minimum required version of WebSphere Liberty is 22.0.0.3 or later.
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-fix_pack.jar 
--acceptLicense install_dir
```
On UNIX operating systems
```
java -jar liberty_download_dir/wlp-base-all-fix_pack.jar 
--acceptLicense install_dir
```
where:

liberty_download_dir

The directory where you downloaded WebSphere Application Server Liberty Base.

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.
Ensure the HCL Workload Automation administrative user that you created 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.
