Engine Controls

From the System Administration tool you can edit and view the status of the JobServer Engine. Using the Engine Control tool, system wide job scheduling can be enabled/disabled and system wide job processing can be enabled/disabled. If the JobServer Engine is in Idling state, these functions will automatically be in disabled state. Also during Gradual startup mode system wide job scheduling and system job processing are automatically disabled.

JobServer Engine Status

This field shows the status of the JobServer Engine. The values can be:

• Running - Scheduling Engine is running allowing Jobs to be scheduled and run.
• Idling - Scheduling Engine is idle. Scheduled Jobs will not run until a Startup (Normal or Gradual) is performed.
• Shutdown in Progress - Administrator has initiated an Immediate or Graceful Shutdown process. JobServer will go to Idling state once shutdown process has completed.
• Container Not Available - This is an abnormal state. Usually means JobServer Container has failed to initialize.

System Clock

Current time used by JobServer.

System Job Scheduling Control

Shows the status of the scheduling engine within JobServer. The administrator has the option of suspending all jobs from being scheduled for the entire system, including all Partitions. If suspended, no jobs can be scheduled for all Partitions. Once scheduling is enabled again, jobs can be allowed to run.

System Job Processing Control

Shows the status of job processing within JobServer. The administrator has the option of suspending all job processing across all Partitions. If suspended, jobs that get scheduled or are run manually, will get put in the Queue, but will remain in the Queue until job processing is enabled again.

When job processing is suspended, all Partitions will be prevented from running any new jobs, whether the individual Partition is enabled or not. This is a system wide control across all Partitions. Jobs that have already started to run will continue to run to completion, but new Jobs will remain in the Queue. Once job processing is allowed again, Partitions can be allowed to run jobs that are pending in their respective Queues.
