Installing
An HCL Launch installation consists of the HCL Launch server, a database, and at least one agent.
- System requirements and performance considerations
  The HCL Launch server runs on Windows™ and UNIX™ systems. Following some guidelines can improve the performance of the server and agents.
- Firewall and communication configuration
  Before you install the server, you must ensure that servers, agents, and other systems can connect to each other through your networks and firewalls.
- Installing the server database
  HCL Launch requires a database. You can use the following database types for an evaluation or production server.
- Installing the server
  The server provides services such as the user interface used to configure application deployments, the workflow engine, the security service, and the artifact repository, among others. Installing the server involves specifying configuration information for the server, such as the ports that the server uses.
- Installing with Kubernetes
  The HCL Launch server can be installed in a cloud-based environment, as a containerized server cluster, managed by Kubernetes. HCL Launch works with Kubernetes to simplify application deployment and manage versions in the containers.
- Installing agents
  You can install agents from the server or from the command line on the agent system. To configure a failover server for an agent, you must install the agent from the command line.
- Installing agent relays
  An agent relay is a communication proxy for agents that are located behind a firewall or in another network location. You can install agent relays in interactive mode or in silent mode.
- Installing plug-ins
  Plug-ins can be installed at any time. You do not need to restart the server after you install a plug-in.
- Starting HCL Launch
  Both UNIX™ and Windows™ installations require the HCL Launch server and at least one agent. If you are using a database other than Derby, make sure that the appropriate driver is installed and configured.
- Backing up and recovering
  You can back up and recover the contents of your HCL Launch installation.
- Installing and uninstalling test fixes (patches) from the server
  Test fixes are provided by IBM® support to correct specific issues. They are applied to the server as patches.

Installing and uninstalling test fixes (patches) from the server

Test fixes are provided by IBM® support to correct specific issues. They are applied to the server as patches.

Before you begin

Ensure that you have the correct version of the server installed, as listed in the readme file for the test fix.

About this task

In most cases, test fixes come with specific instructions. In general, these instructions look like the following steps. However, always use the instructions in the readme file or the instructions that are provided by IBM® support.

Procedure

Stop the server.
Download the file or files for the test fix.
Copy the files from the archive file to the folder app_data/patches folder, where appdata is the application data folder.
The default application data folder is /opt/launch/server/appdata on Linux™ and C:\Program Files\launch\server\appdata on Windows™.
Start the server.
Log in to the server.
Click Settings > Patches and verify that the test fix is installed.

What to do next

To uninstall the test fix, stop the server, remove the files from the patches folder, and restart the server.
