Certain Control-M/Tape utilities require access to the automated tape library interface so that they can update information in the automated tape library database. All relevant Control-M/Tape utilities are APF-authorized and therefore can access the automated tape libraries directly through the interface modules.
The following utilities may pass requests to the central interface module:
