- 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.
