Transaction Processing Using Remote Procedure Calls (RPC) for a Heterogeneous Distributed Clinical Information System

摘要

The Johns Hopkins Hospital is developing a distributed clinical information system that integrates functionally several UNIX, IBM MVS/CICS and MUMPS computer systems. Distributed applications development is accomplished by interprocess communications across Ethernet using remote procedure calls. The remote procedure call (RPC) protocol provides a standard approach to the development of distributed applications using the metaphor of a subroutine call. The Sun Microsystems RPC and XDR (external data representation) protocols have been implemented in these environments. The systems, the distributed model, RPC implementations and applications examples are discussed.
