Availability management of distributed programs and services

Modern distributed applications pose increasing demands for high availability, automatic management, and dynamic conguration of their software systems. This paper presents the architecture of Sampa, a System for Availability Management of Process-based Applications, which aims at fullling these requirements. The system has been designed to support the management of faulttolerant DCE-based distributed programs according to user-provided and application-specic availability specications. It is supposed to detect and automatically react to faults such as node crashes, network partitions, process crashes, and hang-ups. In this paper, we focus on the design of some of its services { the monitoring, checkpointing, and conguration management facilities { and show how they can be used for managing a generic fault-tolerant service.
