AVEVA Batch Management Server Roles and Communications

AVEVA Batch Management Server roles are determined by the information contained in the local RedState file on each server.

Redundant AVEVA Batch Management Server operation is controlled by a redundancy manager service running on each server. The heartbeat is exchanged through the cross-over cable between the two servers. Each redundancy manager controls the other local Batch Management processes. When a failover event occurs, the associated process activity is controlled by the redundancy manager.

A system parameter in the environment called Redundancy TimeOut sets the switch-over delay. You can configure the value. It is specified in seconds.

In the event that a redundant AVEVA Batch Management Server has failed to detect the heartbeat of the other server, it waits for the configured time before initiating a failover.
