Calendar management

The Calendar Manager is a tool that enables you to create pre-defined calendars based on specific scheduling criteria that are used to define scheduling in a job definition. You can create a pre-defined calendar based on one or more of the following calendar types:

• Regular calendars: Enables you to create a pre-defined calendar based on the days of the month and/or the days of the week, as described in Creating a regular or relative calendar.
• Relative calendars (Control-M for z/OS only): Enables you to schedule dates, even if they are not scheduled in a calendar, as described in Creating a regular or relative calendar. In a Relative calendar, the specified date has + or - to indicate how to handle when the marked date is scheduled or not, as one follows:
  • Scheduled: Schedule the date in the relative calendar.
  • Not scheduled: Schedule the closest next date (+) or the closest previous date (-).

  You can use Relative calendars to combine calendars through the Control-M IOABLCAL utility, as described in Control-M for z/OS User Guide.

• Periodic calendars: Enables you to create a pre-defined calendar based on different calendar periods that you define. Periods can be nonconsecutive, of varying length, and overlapping, as described in Creating a periodic calendar.
• Rule-based Calendars: Enables you to create a pre-defined calendar that is based on specific rules, as described in Creating a Control-M Rule-based Calendar:

If Control‑M/Forecast is installed, you can display when and how often jobs are scheduled by clicking View Schedule. For more information on validating your job definition, see Forecast.

If Control-M/Forecast is not licensed at your site, you can use the CTMRPLN utility to produce a report that indicates when jobs in a selected calendar are scheduled to run. For more information, see ctmrpln and the Control‑M for z/OS User Manual.
