About the Cluster Coordinator

The cluster coordinator provides a mechanism for the nodes (represented by the Dgraph processes running on each of the servers) to communicate with each other while ensuring increased availability of the Oracle Endeca Server.

The Cluster Coordinator has the following characteristics:
Note: The Endeca Cluster Coordinator service cannot be configured to run as a Windows service.

Deployment strategy for the Cluster Coordinator service and nodes

The Cluster Coordinator service must be running on at least one node before starting the Dgraph process and its data store on any of the physical servers.

It is recommended that you start a single Cluster Coordinator service on the node that will be designated as the leader node, and then start the Dgraph processes on all servers by referencing the host and port of the Cluster Coordinator.

Note: The port for the Cluster Coordinator is a dedicated port used for cluster node communication.
