Introduction

  • An Active Cluster is an active-active configuration with a number of JobScheduler instances being active at the same time (cluster members).
  • Any task can be executed on any cluster member. The active cluster members agree on the instance that will execute the next task.
  • JobScheduler provides automated fail-over of scheduled tasks between cluster members. 
  • The Active Cluster is intended for load-sharing, i.e. the distribution of tasks to the individual instances, it is not intended for load-balancing, i.e. it does not take into consideration the resource consumption of individual tasks or sizing of the respective server.
