System parameters

Table of contents
No headers

You can reference system and workbook properties from within either a collection or a flow as system parameters. This enables you to do things like specify a file path based on the system’s usage directory or compare a date against the selection date against which the job was run.

You can also create your own workbook parameters to pass values to a collection or flow at run time. For more information, see ETL workbooks.

The following table lists all system parameters using the syntax with which you reference them from a flow or batch job. Many of these parameters reference directories explained in Directory structure:




System installation directory


Name of the current job. This might be a collection or flow from a workbook, a legacy batch job, an internal job, or a report job.


Name of the current process. In the case of a collection or flow, this is the workbook name.


Select date in yyyyMMdd format


Day of the month of the select date, as two digits


Month of the select date, as two digits


Year of the select date, as four digits


Beginning of the select date, in milliseconds, since the beginning of the Unix epoch.

For more information, see Unix time.


End of the select date, in milliseconds, since the beginning of the Unix epoch.


Time zone of the Cloud Cruiser server


Directory for job files


Root directory for all batch logs


Root directory for all processing. Each process creates a child directory here.


Directory for the current process


Directory for sample jobs


Default location for scripts to execute as job step


Directory for email templates


Default location for usage data not in CC Record file format

In this example, the system parameter ${env.baseDir} is part of a file resource specification.

<bean id="sampleCSVReader" class="com.cloudcruiser.batch.collect.SmartFlatFileCollector">
  <property name="resource" value="file:${env.baseDir}/samples/sample.csv.txt" />
  <property name="feedConfig" ref="sampleCSVFeed"/>
