- High availability and failover
  You can configure clustered HCL™ Launch servers, and agents for high availability. You can also configure agents and agent relays for failover.
  - High availability overview
    To configure clustered high availability for HCL™ Launch, you must use a load balancer. You can configure a cold standby server by using a load balancer or configuring the servers' DNS.
- 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.
- Backup and recover
  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.
- 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.
- Releasing VC LOB space
  After you upgrade to HCL™ Launch 7.0.5 and later, you can compress the amount of large object (LOB) storage space that HCL Launch uses in the vc_persistent_record database table.

High availability and failover

You can configure clustered HCL™ Launch servers, and agents for high availability. You can also configure agents and agent relays for failover.

In most cases, you configure servers to be part of a high-availability cluster when you install them, but you can also convert existing servers to a cluster. To configure a high-availability cluster of HCL™ Launch servers, see Setting up high-availability clusters.
