Configuring virtual servers

Information noteNote: Only users that have the Operation Manager role and rights can have read-write access to this page. Other users, depending on their roles, can have either read-only access or no access to this page.

A virtual server is a group of physical servers. By default, the best rated server is preferred at Job execution time. If the random.jobserver.selector property is set to true in configuration.properties, Talend Administration Center selects a random available server in the virtual server instead. If the Job is already deployed on one server, that server remains preferred for execution.

In Talend Administration Center, simply select physical servers and group them into a virtual server. Then set the execution task onto this virtual server as for any execution server.

Access to the Virtual servers page depend on your license. For more information, see What modules and features are available depending on your license.

For users working in cluster mode via virtual servers, note that the default ranking of servers used for load balancing is based on indicators, whose bounds (such as free disk space limits) and weight are defined in the monitoring_client.properties file which is located in <ApplicationPath>\WEB-INF\lib\org.talend.monitoring.client-A.B.C.jar. These values can be edited according to your needs. For more information, see Configuring the indicators which determine which server to be used for load balancing.
