For the task management of Oracle, if you have a clear understanding of the three key contents, you can fully grasp the task, which is described in detail as follows:

1. Concept analysis

PROGRAM-Program. Job entities that can be executed. Scheduler-Plan. Or a schedule, that is, a schedule for when to do things. JOB-Task. The whole thing, including what to do and how to arrange the time. 2. Concept understanding

What is program? Is to tell people what to do. Then tell others how to arrange the time to do it repeatedly or at a single time, then this arrangement belongs to the scheduler, what to do, when to do it, and whether to repeat it after doing it once, then the whole is a JOB.

For example, as an administrator, if you want to start report statistics tasks at 04:00 every Saturday morning, you can first configure a program about report statistics (PROGARAM), then schedule a schedule (scheduler) (04:00 every Saturday morning), and associate the first two to create a task (JOB).

Therefore, JOB includes SCHEDULER and PROGRAM. I don't know if you understand clearly.
