Execution of scheduled tasks in the administrative task scheduler

The administrative task scheduler manages the point in time, the security, the input parameters, and the status of task execution.

The work of the administrative task scheduler is based on scheduled tasks that you define. Each task is associated with a unique task name. Up to 9999 tasks are supported in the administrative task scheduler at one time.

A scheduled task consists of a schedule and a work definition. The schedule tells the administrative task scheduler when to execute the task. You define a window of time during which execution is permitted, and either a time-based or event-based schedule that triggers the execution of the job during this window. The work definition specifies what to execute, either a JCL job or a stored procedure, and the authority (user) under which to execute the task.
