Process status information can be stored in the Process Engine database component (the default configuration), or it can be stored in RAM. You select the method of storage by setting the Volatile Tracking option in the process properties of Designer (different process models may use different configuration settings). A Process Engine stores the details of a process—such as start time, end time, and whether is it active or disable—in the selected location.

For more information about setting the Volatile Tracking option, see Setting Quality of Service for a Process. For more information about how the Process Engine maintains status data, see the topic “Tracking Process Status” in the webMethods BPM Process Development Help.
