Failover Batch Scheduling
JAMS provides completely transparent failover support, allowing one or more JAMS Schedulers to failover automatically to standby systems so that jobs and processes are executed on or near schedule in the event of a failure of the primary JAMS Scheduler(s).
When a primary JAMS Scheduler fails or is unresponsive, one of the failover JAMS Schedulers will go active and assume all of the management of activities that the primary JAMS Scheduler had. The failover JAMS Scheduler will then connect to all JAMS Agents to ensure all processing runs. Once the primary JAMS Scheduler comes back online, the primary JAMS Scheduler will once again gain control of the schedule and the failover JAMS Scheduler will revert to its sleep mode.
In a cluster aware job scheduling architecture, JAMS uses an active-passive scheme where the primary JAMS Scheduler is in an active setting, managing and dispatching processes across your organization's infrastructure. The passive JAMS Scheduler resides on another machine in the cluster, monitoring the primary JAMS Scheduler to ensure that everything is running according to plan.
