Like the Transport Management System, ActiveControl has the concept of a “domain controller”. The domain controller does not need to be configured in any special way, it is simply the SAP system that the ActiveControl client software connects to, and is where ActiveControl configuration and application data is stored.
The server software runs mostly within the ActiveControl domain controller. When necessary, the domain controller connects to the other SAP systems to gather change request information and to perform transports. These connections are made using SAP’s remote function call (RFC) protocol.
The Integration Engine is part of the Domain Controller and manages communication with external products and systems.
More information on this can be found in the ActiveControl Administration Guide, available here.
