Stages of Job Processing

The following illustration shows the different stages of job processing in detail.

Activation
RunID is created	Generation
Job appears in the Activity Window	AE Script is executed in the Pre-Process and Process tab	Transfer
	Final JCL is generated	JCL is transferred to the agent	Execution
			Job is executed	Transfer
			Runtime commences	Report is transferred to the Automation Engine	Post Process
					Post Process is executed (if available)

Some checks are made before the job is executed in the order shown below :

Was the job canceled in the meantime?
Should the job be started manually?
Does job execution depend on Sync objects?
Was the maximum number of jobs reached that may run parallel on the agent?
Is the agent active?

Finding Jobs After Agent Downtime

When an agent ends and is then restarted, it obtains the whole restart information from the Server - i.e. about all jobs that were being executed at the time the agent ended. Of course, jobs might have ended during the agent's downtime. The agent starts searching for jobs in the process lists of the particular operating system. If it does not find a job anymore, it searches for its report file in the temporary directory and retrieves the point in time when the particular job has ended and its return code. If the agent is not able to find any information, the job status changes to "V - status vanished".
