Cluster

ActiveVOS Server supports clusters of process servers operating with a single persistent process store.

Multiple process servers share a set of process instances and their deployments. Two main features of a clustered environment are load balancing and fail over. Load balancing allows processes to be routed to the server in the process cluster with the least load. Fail over allows servers to pick up the load of a failed server in the process cluster.

The engine cluster details include the following.
