Observation of Distributed Computations: A Reflective Approach for CORBA

Abstract : This paper describes some reflective programming techniques to observe a distributed computation in a CORBA environment. First, we propose a new order relation to translate causal dependencies in a distributed program. We generalize Lamport's Happened before relation defined for message passing applications, to an object causal relation between distributed events in an environment with synchronous and asynchronous method calls, method synchronizations and variable sharings. Second, we propose a reflective approach to observe this relation. Finally, a tool is provided to display the causal dependencies graph of a distributed run.
