    The paper describes an environment for interactive configuration management of the software components comprising a distributed enterprise application. The environment permits one or more managers to view and modify the structure of components in terms of component instances, their allocation to hardware nodes and the bindings between their interfaces. The graphical management is based upon the Da... View full abstract»

    Interworking traders allow their clients' requests and their servers' advertisements to go across the boundaries of trading communities. Interworking is accomplished via trader links. The OMG (Object Management Group) and the ISO ODP (Open Distributed Processing) Committee have published a paper (OMG RFP5 Submission, “Trading Object Service”, OMG Document orbos/96-06-07) which specifie...

    IT systems play an ever increasing role in business, commerce, government and services, and can be involved in making decisions that carry enormous implications. This implies that these machines carry responsibility for those decisions and for their outcomes. This paper considers the implications of such “machine responsibility” both for the enterprise concerned and for the IT system, ... View full abstract»

    We propose electronic contract negotiation-a sub-part of the more general area of electronic commerce-as an example application for mobile agents. We start by presenting a set of requirements that an application should fulfil in order to take advantage of mobile agents and show that not all distributed applications meet these requirements. We then present contract negotiation, an example of an app... View full abstract»

    Much of today's software development involves reengineering legacy applications, but the bulk of research and tools address new software development. The Distributed Object Management Integration System (DOMIS, 1993-96) project investigated how legacy applications can be incrementally modified, or migrated, by using distributed object management (DOM) technology. The paper describes a methodology ... View full abstract»

    The paper presents the development of a distributed architecture for the factory automation domain by applying the object-oriented domain engineering (OODE) method. The first part of the paper talks about extending formally defined object-oriented analysis and design (OOA&D) methods with domain engineering (DE) concepts. It defines the resulting OODE workflow, deliverables, and development cyc... View full abstract»

    Previous work on long-running transactions for multi-database environments relaxes the isolation requirement of conventional ACID transactions. However, most of that work does not provide mechanisms to explicitly enforce isolation. This paper proposes a framework in which long-running transactions can specify global predicate-based locks to enforce limited forms of isolation between selected trans... View full abstract»

    Enterprise roles define the duties and responsibilities of the individuals which are assigned to them. This paper introduces a framework for the management of large distributed systems which makes use of the concepts developed in role theory. Our concept of a role groups the specifications of management policies which define the rights and duties corresponding to that role. Individuals may then be... View full abstract»

  • Mobility support: a multi-domain bridging matter

    We view mobility support as a bridging matter between fixed and mobile domains. In single domain systems, mobility is implicitly supported by access and location transparencies provided by the distributed processing environment (DPE). Distributed telecommunication systems span, however, several domains that are controlled by different actors and may also be fixed or mobile. Mobility is no longer a... View full abstract»

    A common problem in distributed systems is the selection of a particular service instance from a set of possible services. In this paper, we identify the kinds of information required to select services within enterprise distributed systems and present a flexible mechanism for selecting services. This mechanism enables clients to build complex queries that are able to utilise script-based interact... View full abstract»

    The Component Object Model (COM) (and by definition, DCOM) is the only component system where there is a significant market for commercially available components. This paper discusses the elements of COM's design that have all contributed to making COM such a viable commercial reality: black box-encapsulation, interfaces, interface immutability, multiple interfaces, and location transparency View full abstract»

    Meta-modeling is critical to the success of distributed object environments such as CORBA and ActiveXI DCOM. However, there is a surprisingly large variation in the nature of the meta-models (and meta-meta-models) that have been proposed for such environments. This paper investigates this phenomenon by examining the basic tenets of meta-modeling in the context of distributed object environments, a... View full abstract»

    Telecooperation receives increasing importance in a globalized information and work infrastructure. Among others, teleconferencing and workflow management are technological areas being studied and developed to support telecooperation scenarios. i.e. real-time collaboration tasks are being supported by teleconferencing systems, asynchronous tasks are being supported by workflow management systems. ...

    Online transaction processing (OLTP) applications have special requirements in the areas of scalability and performance. Mincom currently markets a successful product, MIMS (Mincom Information Management System), which is a large, integrated OLTP system consisting of about 16,000 KLOC (kilo-lines of code), mostly COBOL. Our research group is developing prototypes in preparation for migrating MIMS ... View full abstract»

    Current approaches for service mediation, such as trading, do not provide means for a long-term binding of services. They do not ensure that certain services are provided and that the desired service properties are fulfilled. Moreover, a server may withdraw a service offer at any time. For the integration of external services into an enterprise internal service market, it is necessary to guarantee... View full abstract»

    Reuse of software components available in open distributed systems is a promising approach for efficient development of complex distributed applications. In open distributed systems, type mechanisms are used both to find appropriate external software components and also to guarantee that their respective interfaces match. Furthermore, a type manager allows application developers to interactively b... View full abstract»
