High Availability Failover

|
The ActiveBatch Job Scheduler currently uses an active-standby scheme similar to Microsofts or Symantec Cluster facility. The primary Job Scheduler is in active mode and dispatching jobs. The other Job Scheduler(s) enter a standby mode monitoring the "heartbeat" for the preferred Job Scheduler.
When an active Job Scheduler fails or is deemed unresponsive, one of the standby Job Schedulers will attempt to go active and take over the job scheduling load.
With the use of Microsoft's Active Directory and ActiveBatch Enhanced Directory Services the starting or failover of the ActiveBatch Execution Agent on a Windows or Non Windows systems is enhanced. This combined capability allows both Windows and non-Windows systems, in particular, to have access to publishing and high-availability features that would otherwise be only available on the Windows platforms. In addition the ActiveBatch client systems, within that ActiveBatch scheduling environment, will seamlessly failover to the new scheduler and all jobs will continue to be executed.
Minimum Requirements:
The ActiveBatch High Availability Failover component is separately licensed and is installed on a per job scheduler basis. No special software is required on the client's machine and an unlimited number of client machines are fully supported.
