Job Management Partner 1/Automatic Job Management System 3 Overview

3.4.2 Monitoring generation and execution generation

When a jobnet with a start condition is executed, two types of generations are generated: a monitoring generation, which controls monitoring for the occurrence of an event, and an execution generation, which waits for the occurrence of the event. When the event being monitored occurs, the start condition is satisfied and the execution generation is executed.

The following figure shows the monitoring generation and the execution generation.

Figure 3-42 Monitoring generation and execution generation

When a jobnet with a start condition that has been registered for execution starts at the start time specified for a schedule rule, a monitoring generation in the Now monitoring status and one or more execution generations in the Wait for start condition status are generated.

If an event occurs and the start condition is satisfied, the execution generation in the Wait for start condition status is placed in the Now running status, and a new execution generation with the Wait for start condition status is generated.

Note that when monitoring terminates, the monitoring generation in the Now monitoring status is placed in the Monitor-end normal status. If the condition has not been satisfied before the monitoring terminates, the generation is placed in the Unmonitored + Ended status. If an error occurs in a monitoring generation in the Now monitoring status, the execution generation is not executed even when the start condition is satisfied, but is instead placed in the Ended abnormally status.

You can check these statuses from the Daily Schedule window or the Monthly Schedule window.
