Job Life Cycle

When a job enters the production schedule, it begins a life cycle consisting of five general phases:

1. The job waits in the schedule for its dependencies to be met.

2. The job enters a queue and waits for an execution slot to be available.

3. The job is launched on an agent.

4. The job runs.

5. The job completes and enters history.

Throughout the life cycle of a job, it goes through a variety of conditions that affect it. Some of these conditions arise from factors that occur within the job process and other conditions arise from factors outside of the job’s life cycle. Some conditions are recognized as key occurrences within the process of job scheduling by designating them as event triggers.

Once the event condition is defined, a predefined action must be associated with it. In effect, an event defines a cause and effect-when this condition occurs, do this. Defining events allows you to create automatic responses to conditions within your system.

Some of these event triggers are predefined by TA as internal events and some events are defined externally by users as conditions to be monitored by event monitors during designated times periods.

These event triggers are grouped into different categories according to the type of conditions that create the events.
