The design of Sampa [high level support of distributed applications]

We present some of the design goals and the architecture of Sampa. Sampa stands for System for Availability Management of Process-based Applications. The goal of Sampa is to provide a high-level support for the management of distributed applications and services implemented on the top of the OSF Distributed Computing Environment (DCE). Sampa is fully decentralized and gives support for monitoring, controlling and reconfiguring fault-tolerant applications and services. It is composed of base services, a set of cooperating management agents executing on every node of the system, and a management supervisor, which implements the high-level management functions and the interface with the user. In this paper, we focus our attention on the protocol used for the mutual control of the management agents within Sampa
