How to Schedule a Process from RapidMiner Studio

To run a process on a specified date and time, or regularly at a specified time, use the scheduling feature. This feature is only available to processes that are stored on RapidMiner Server.

Accessing the scheduler

From theProcessmenu pull-down of RapidMiner Studio, selectSchedule Process on Server:

TheRun process on RapidMiner Serverdialog opens with theScheduletab selected:

Complete the fields then clickScheduleto run or schedule your process. The following table describes the settings:

Field	Description
Repository	Select the Server instance on which you want to run the process. Or, click theCreate repositoryicon toconfigure a new Server repository.
Process location	Enter or browse to the location of the process to run.
Process execution queue	Select a queue to execute the process. By default there is only a single simple process execution queue, which imposes no execution restraints. You canconfigure additional queuesas required.
Now	Sets the selected process to run as soon as you clickSchedule. This executes the same action asRun on Server Nowoption, but allows you to specify a process and location instead of opening it in theProcessview of theDesignperspective.
Once	Sets a future date and time to run the selected process. Use the calendar to select a date or enter it manually; enter the time manually in the format displayed in the field.
Cron schedule	Allows you to build a cron expression (a trigger), either manually or with theCron编辑器, to schedule the specified process for repeated executions. You can also schedule a future single execution using theCron编辑器.

Understanding the cron expression builder

You can create a cron express by 1) manually entering the expression or 2) using the cron expression builder:

Note that if you use the builder, upon completion RapidMiner displays the settings in the cron expression language.

Once your expression is complete, you can use theStartandEndselectors to set a start or end time for the trigger to be applicable.

Rules for manual expressions

Using the Cron Editor

Using the built-inCron编辑器, you can build cron expressions without knowing the cron utility's syntax. To use the editor, click theicon.

TheCron编辑器使用的日期格式dd-mm-yyyyand the time formathh:mm:ss. WhenSeconds,Minutes, orHoursis set toOnwith a value, it sets thess,mm, andhhat which the trigger fires. This time is in conjunction with the other settings. For example, setting theSecondsfield to 15 fires the trigger at hh:mm:15, not every 15 seconds.

Note: IfSecondsis left in the default positionEvery Second,trigger fires once a second (this is strongly discouraged). It is best to set the field toOnwith a value. Usually, this is true for theMinutesfield as well.

The following table describes each field in theCron编辑器:

Setting	Description	Values
Seconds	Sets the seconds (ss) field for the trigger, expressed ashh:mm:ss. Optionally, set the offset in seconds to repeat from the initialss.	0-59
Minutes	Sets the minutes (mm) field for the trigger, expressed ashh:mm:ss. Optionally, set the offset in minutes for repeating from the initialmm.	0-59
Hours	Sets the hour (hh) field for the trigger, expressed ashh:mm:ss, in 24-hour clock format. Optionally, set the offset in hours for repeating from the initialhh.	0-23, where 0 is midnight
Days	Sets the day(s) on which the trigger fires. Options for setting the day are: Every Day: fires the trigger every day at the specified time, month(s), and year(s). On: fires on daydd, and optionally repeated every number of days. Use Days of Week Condition: fires on the selected days at the specified time, month(s), and year(s).	1-7, where 1 is Sunday
Months	Sets the month(s) in which the trigger fires. Options for setting the month are: Every Month: fires the trigger every month at the specified time, day(s), and year(s). On: fires in monthmm, and optionally repeated every number of months. Use Days of Week Condition: fires in the selected months at the specified time, day(s), and year(s).	1-12, where 1 is January
Years	Sets the year(s) in which the trigger fires. Options for setting the year are: Every Year: fires the trigger every year at the specified time, day(s), and months(s). Enable Year Condition: fires in the selected year, and optionally repeats every number of years specified.	From current year to current year + 100

The following illustrates the setting for a process that is to run every Monday and Wednesday at 7am local time for the first quarter of the year:
