Cron | X4Documentation

New configurations for executions at server startup can be created via the Cron button. A number of options and parameters are available for this. These are explained in more detail below.

Options

Name	Freely selectable name for execution
Process	Path to the process in the `X4DB` Example: `Processes/Activities/Processes/Process.wrf` Click Browse... or drag and drop a process into the field to select a process. The process must be in the same project as the scheduler. The process must not be a sub-process of another process.
Active	Activates the scheduler
Generate Cron expression	Generates a Cron expression Possible values: `Minutes` `Hourly` `Daily` `Weekly` `Monthly` `Yearly` In the Source tab you can edit the Cron expression manually. Generating a cron expression is not possible if the cron expression was edited manually.

Parameters

In the Parameters section you can define any number of parameters for the run configuration.

	Add row
	Remove row
Key	Name of the parameter (any string, ideally `NCName`).
Value	Optional parameter value

The scheduler creates an XML file as input for the process, which contains the defined parameters. The input XML file is loaded directly into the process at the start component.

As the parameter values are only directly accessible when the process is started, they must be saved (e.g. as a variable) if they are to be used later in the process.

Example:

XML

<?xml version="1.0" encoding="UTF-8"?>
<Execution jobId="JobId" executionId="ExecutionId" executionName="ExecutionName">
  <Parameters>
    <Parameter name="ParameterKey">ParameterValue</Parameter>
    <Parameter name="ParameterKey">ParameterValue</Parameter>
    <Parameter name="ParameterKey">ParameterValue</Parameter>
    ...
  </Parameters>
</Execution>
