Abstract

A distributed system includes a non-distributed computing environment (DCE) computer system and at least one DCE computer system which are loosely coupled together through a communications network operating with a standard communications protocol. The non-DCE and DCE computer systems operate under the control of proprietary and UNIX based operating systems respectively. The non-DCE computer system further includes application client software for providing access to distributed DCE service components via a remote procedure call (RPC) mechanism obtained through application server software included on the DCE computer system. A minimum number of software components modules which comprise client RPC runtime component and an import API component included in the non-DCE computer system and an Ally component on the DCE computer systems to operate in conjunction with the client and server software to provide access to DCE services by non-DCE user applications through the RPC mechanisms of both systems eliminating the need to port the DCE software service components onto the non-DCE computer system.
