Experimentos de Tolerância a Falhas em Java
Abstract
In the object model, programs consist of encapsulated components, which interact through well-defined interfaces. The interactions among the components depend on the current system or program architecture as well as the execution environment: sequential, parallel or distributed. Also aspects of the environment in which the system operates cannot be ignored by the system specification. An improper environment can trigger a component/interaction fault, so its important to bound the system influence over the running program. Even when executing replicas of the same base component, small differences in the system behavior can lead the program to a faulty state. This paper is actually about the similarities and differences among the several ways the components interact and their execution environment. A major goal is to test the adequacy of Java programming language and its several virtual machines to implement fault-tolerant applications.
