How Job Management Manager Works › Special Days

Special Days

Special Days are those days requiring particular consideration when scheduling jobs. You can prevent a job from running on Special Days or restrict a job to run only on Special Days. Examples of Special Days are New Year’s Day, Thanksgiving, and Christmas, and company holidays, plant shutdown days, and vacation days.

Special Day Classes are collections of calendar dates, grouped for specific reasons (holidays, plant closing days, and so on).

Job Management Manager Special Day support lets you:

• Define Special Day Classes.
• Define as many Special Days as you like within each class.
• Control how jobs are scheduled on Special Days.
• Use combination of Special Day Classes to affect the scheduling of any job.

You need OPER or SYSPRV permission to create, modify, or delete a Special Day Class.

In the DCL interface, elements of a Special Day Class are defined in terms of absolute date specifications, such as 24-MAR-2012. In the DECwindows interface, you define Special Days by clicking days in a calendar.

See Defining Special Day Classes, for Special Day class naming rules.

Once defined, one or more Special Day Classes can be used in combination as a scheduling constraint for a job, with either of the following controls:

• Restricting the job from running on the Special Days specified
• Requiring the job to run only on the Special Days specified
