SystemConfigure for Load Balancing

In a Spectrum environment using distributed services, you can configure Spectrum to load balance data services and most core services among all Spectrum Application Servers. This approach typically prevents any noticeable interruption for users if a server goes offline.

Important! In a Spectrum environment with distributed services, all Spectrum Application Servers that are online must be accessible to each client computer.

Tip: To prevent disruptions for users, it is recommended that you configure your Spectrum environment for high availability (load balancing with failover) rather than load balancing alone. For more information, see Configure for High Availability.

Although you can load balance services among all of your servers, depending on your environment and the capabilities of your servers, you also have the potential to optimize specific servers for specific tasks. For example, you can configure one or more servers to primarily support device group services.

To configure a service to be load balanced among all Spectrum Application Servers, use the following procedure.

  1. In System System Management > Service Management, locate the core service or data service that you want to manage.

    Note: The Service Management page is primarily relevant if your Spectrum environment includes two or more Spectrum Application Servers installed as a distributed environment. For information about how to create a distributed Spectrum environment, see the Loftware Spectrum Installation and Configuration Guide.

  2. If the Concurrent Running Servers property is displayed, select All to indicate that all Spectrum Application Servers in the distributed environment for which the service is activated should run the service concurrently.

    Note: If the Concurrent Running Servers property is not displayed, then the service does not support load balancing. For information about configuring a service for failover instead, see Configure for Failover.

  3. In the instances table, select Activate for each Spectrum Application Server.

    Important! The Font Management Service should be activated and started on all Spectrum Application Servers to ensure consistent fonts.
