Control-D activates two monitors, the Control-D monitor and the Printers Control monitor. The Control-D monitor scans its active environment file and other files to determine when missions are processed. It processes missions, tracks their execution and analyzes the results.

If Control-V is installed, this monitor also handles indexing of reports and their migration to other storage media, such as optical storage or cartridges.

The Control-D Printers Control monitor creates subtasks for each print mission, thus enabling parallel execution of print missions.

If Control-D/WebAccess Server is installed, the Control-D file Transfer monitor can transfer Control-D/WebAccess Server packets from the mainframe to the PC. This monitor scans the Active Transfer file and determines which packets are transferred. Control-D and Control-V describes the File Transfer monitor.

The Control-D Application server provides access to Control-D and Control-V User Report files by Control-D/Page on Demand. It is activated by the IOA Gateway monitor. For more information, see Control-D and Control-V.
