User and mechanism views of distributed systems management

Abstract
This paper discusses the concepts developed within the DOMINO project on Domain Management for Open Systems, and how these concepts are implemented. Domains are a means of grouping objects, distinct from the management policies which are specified in terms of domains. Domains and policies are discussed from the viewpoint of both the manager and the underlying mechanisms which implement them. The emphasis of the user view is on conceptual clarity and the emphasis of the mechanism view is on efficient implementation in distributed systems. Both views need to be implemented, although in some cases there may be a direct correspondence between the two views. The paper argues that keeping managers independent from the domain of objects they manage gives flexibility and simplifies both the user and mechanis m views of system management.
