Job Scheduler

Access the Oracle Job Scheduler.

A job assigns a task to a schedule. The job tells the schedule which tasks - either one-time tasks created "on the fly," or predefined programs - to run. A specific program can be assigned to one, multiple, or no schedule(s); likewise, a schedule may be connected to one, multiple, or no program(s).
