1.3 Job execution unit and job execution ID

For each job, an ID (called a job execution ID) is assigned depending on its schedule and the results. A job execution ID is assigned to each execution unit, such as today's execution unit or the next day's execution unit. Each unit is determined by schedules or results of execution conditions.

A job execution ID is assigned when an execution schedule is generated. For a job executed on time, a job execution ID is assigned when the job is registered and when the next execution schedule is calculated after the job is started. For a job executed on event, a job execution ID is assigned when a job is registered, or when a schedule to wait until the next execution condition is satisfied after an execution condition is met, is generated.

The format of a job execution ID is composed of 36 alphanumeric characters (in hexadecimal) and hyphens (-) as shown below.

Once a job execution ID is assigned, it does not change unless you re-register the job or change the schedule. Each job execution ID is unique. There are no duplicates of job execution IDs of other jobs or those of executions in the past.

You can use the cpareport command to see job execution IDs. For details, see cpareport in 9. Commands.
