Abstract

In a distributed object-oriented computing environment, many exceptions would occur because many objects run concurrently on several computers connected by a network. Therefore, exceptions in distributed applications will be more complex than those in ordinary (not distributed) applications.In this paper, we introduce an exception-handling framework into our distributed object-oriented computing environment (DOOCE). In particular, we focus on handling the multiple exceptions, which are propagated from concurrent active objects in our system. The exception handling in DOOCE provides two models; termination model and resumption model and can handle the occurring multiple exceptions. Programmers have the flexibility of either handling all exceptions individually or grouping all exceptions together and handling them as a single. Furthermore, we propose a 驴notification message驴 as an approach to perform an exception occurred during the parallel computation.
