TP1/Client performs RPCs using the name service function of TP1/Server. TP1/Client manages OpenTP1 system service information using the name service function.

Since TP1/Client uses the cache for service information, it minimizes inquiries into the TP1/Server name service. If the cache contains no service information or the effective cache period expires, TP1/Client communicates with the TP1/Server name service.

To minimize communications between TP1/Client and the server, you can disable the TP1/Server name service function. In this case, an RPC generates no name service inquiry, decreasing communication load between TP1/Client and the server. This is useful when TP1/Client is connected to the server via WAN.

Specify whether to perform the RPC without the name service using DCSCDDIRECT of the client environment definition.

The name service function directly allows a remote service request such as the schedule service for DCHOST in the client environment definition or the host computer specified when the user authentication is executed. When this function is used, RPCs are unavailable for the socket-receiving type server SPP.
