What is transport domain controller in SAP

TDC acts as a leader for all the systems within a transport domain

The transport domain contains all SAP systems whose transports are to be administrated jointly. One of these SAP systems is chosen as the transport domain controller.
Since all activities relevant to the entire transport domain, such as configuring transport routes or RFC connections, can only be carried out on the domain controller, the SAP system selected to be the domain controller should have:
High availability
A high level of security
A high level of maintenance

The domain controller is normally configured on a production system or a quality assurance system. Out of several reason you may choose to set up an SAP System dedicated to tasks that may be carried out CENTRALLY. This includes the task of the TMS domain controller.
The system load on the SAP system that is chosen as the domain controller is low, and only increases for a short period when the TMS configuration is changed.
