The first system started in the cluster assumes the Coordinator role and additional systems become Participants in the cluster. If the system acting as the Coordinator becomes unresponsive, the first Participant in the cluster will assume the Coordinator role.
Coordinator Duties
Executes all background jobs (for example, purging processes and Web User password expiration notifications).
Keeps track of all IP addresses that are being monitored for auto-blacklisting.
Accepts file transfer connections from Web Users.
Distributes the processing of Monitors (for scanning folders) evenly across all systems in the cluster.
Maintains the Scheduler and determines which jobs to execute.
If there are active jobs running on a Participant system when it shuts down, the Coordinator will set the status of those jobs to canceled.
Participant Duties
Monitors active systems to detect if the Coordinator has left the cluster.
