Can the Job Scheduler run in load balanced or fault tolerance mode?
This feature is partially available: load balancing is available for order driven job implementations only, have a look at the section “order processing” in this flashmovie Concerning fault tolerance we distinguish job errors and scheduler errors: Job Errors: jobs may be configured to repeat automatically after errors in configurable intervals and number of trials. Job Scheduler Errors: if the scheduler is operated with a database (which is not required) then automatic reconnects are available with a configurable number of trials. there are mechanisms to Monitor errors, i.e. multiple Job Scheduler instances on the same or different servers send heartbeats to a Job Scheduler that is operated exclusively for monitoring; Respawn a faulty Job Scheduler instance; Do some “sanity checking” for disk space and memory usage by maintenance jobs. Fault tolerance is not available in the sense of automatic failover: if resources (disk space, database etc.) run short, then the Job Scheduler will fin
