In order to increase the utilization of the computing resources, universities connect a variety of computing resources such as mainframes, workstations, and personal computers via LAN. However, due to management and security reasons, most administrative applications are concentrated on mainframes which is the main cause of large work overload on mainframes for such applications as on-line course registration system where the entire student body must have access to the system during a short period of time. In this study, using a university system as the model and choosing on-line course registration system as the targeted distributed computing. APPC through IBM SNALU 6.2 link is proposed as the most appropriate means of distributed computing for the environment of the model university. In addition, the on-line course registration system is redesigned as client-server model where a mainframe serves as the file server responsible for file input and output and workstations becomes the client. Actual implementation and experiments have shown that the proposed distributed computing system yields a significant reduction in processing time.
