A messaging architecture for distributed objects in Oberon

Abstract

Abstract.A distributed messaging architecture built on top of current Oberon System 3 implementations is designed and implemented. It is aimed at supporting a CORBA-inspired object request broker architecture for distributed objects. The emphasis is on compatibility with System 3 messaging without requiring modifications of existing systems. Some Oberon-specific issues are identified which require workarounds in the solution, and proposals are also made for improved distributed messaging support in future systems. The implemented solution is presented in detail and uses a precompiler for message-specific communications procedure generation without restricting runtime flexibility for message types.
