Installing
An HCL Launch installation consists of the HCL Launch server, a database, and at least one agent.
Upgrading and migrating
Learn how to upgrade HCL Launch elements, including the server, agents, and blueprint design server, and how to migrate data.
Uninstalling
Learn how to uninstall an HCL Launch server, or agent.
Integrating
HCL Launch supports integrations with other IBM® products, products from others, and certain cloud systems.

- High availability and failover
  You can configure clustered HCL Launch servers, blueprint design servers, and agents for high availability. You can also configure agents and agent relays for failover.
- Setting up high-availability clusters
  To configure a high-availability cluster, you store shared files on network storage. Then, you configure multiple servers, set each server to access the same files and database, and configure a load balancer to distribute the traffic between the servers.
- Adding cold standby servers
  You can add cold standby servers to serve as a backup server or for disaster recovery. You must start the secondary server or servers when the active server fails, and network traffic is routed to the secondary servers.
- Backing up and recovering
  You can back up and recover the contents of your HCL Launch installation.
- Server settings and configuration
  After you install HCL Launch, you can modify the server configuration and configure more options.
- Setting user preferences
  Each user can specify display options for the server, including the language for the server and how the server shows times and dates.
- Agents and agent relay configuration
  After you install an agent for HCL Launch, you can modify its configuration or create an agent relay to facilitate communication to remote relays.
  - Configuring agents for failover
    To configure agents for failover, you specify two or more target servers for the agent to use. If one of the servers fails, the agent switches to another server from the list.
  - Configuring agent relays for failover
    To configure agent relays for failover, you specify two or more target servers for the agent relay to use. If one of the servers fails, the agent relay switches to another server from the list.
  - Changing or updating the JRE of agents
    You can change the JRE of active agents by editing their configuration files.
  - Changing passwords for the agent relay keystores
    You can change the Java™ keystore passwords for the agent relay.
  - Caching artifacts on agent relays
    Agent relays can cache downloaded artifacts. Caching artifacts in this way improves performance because agents retrieve artifacts from agent relays instead of from the server.
  - Migrating Agents to Web
    Agent Configuration Templates allow you to migrate JMS agents on a server to Web agents with the ability to revert back to the original JMS configuration. This allows you to specify connection details for groups of agents.
  - Migrating Agents Relays to Web
    JMS agent relays on a server can be migrated to Web with the ability to revert back to the original JMS configuration. This allows you to specify connection details for groups of agent relays.
  - Agent security and communication
    Agents use SSL-secured JMS, WebSocket, HTTP, and HTTPS protocols to communicate with the server.
  - Removing and reinstalling agents as Windows™ services
    If you installed an agent as a Windows™ service, you can remove and reinstall the service.
  - Managing agents remotely
    After an agent is installed, you can manage (with the monitor process) many of its features from the HCL Launch web application.
  - Agent relay actions
    After an agent relay is installed, you can manage many of its features from the HCL Launch web application.
  - Setting agent properties
    Agent properties store information that is relevant to a specific agent.
  - Creating and managing agent pools
    Similar to resource groups, agent pools help you organize and manage agents that are installed in different environments.
- License management
  HCL Launch provides a 60-day license-free evaluation period. To use all product features after the evaluation period, you must have a license.
- Setting up the wizard for new users
  HCL Launch includes a wizard to help users become familiar with the procedures and steps in creating a deployment. Some configuration is required before the wizard can be used.
- Customizing the table views
  Customize a table view in the HCL Launch application by hiding or showing, and reordering of the table columns.
- Managing data
Managing security
HCL Launch uses a flexible team-based and role-based security model that maps to your organizational structure.
Modeling software deployment
Modeling software deployment in HCL Launch includes configuring components and component processes and adding those components to applications. Then, you use processes to deploy the components to environments.
Deploying
Learn how to deploy applications in HCL Launch.
Reporting
provides several different deployment and security reports.
Extending product function
Learn how to extend the function of HCL Launch.
Troubleshooting and support
Learn how to troubleshoot some common issues with HCL Launch.

Agents and agent relay configuration

After you install an agent for HCL Launch, you can modify its configuration or create an agent relay to facilitate communication to remote relays.

To monitor the status of the relay and the agents that are connected to it, click Resources > Agent Relays. This tab shows the number of active and offline agents that are connected to each relay, as shown in the following figure:
