    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»

    The telephone network could be called the world's first distributed object computer system. The high reliability, availability and capacity requirements of the telephone network have forced the telecommunications industry to solve a number of key challenges. This paper discusses the applicability of these solutions to other areas of distributed object computing using the concept of “design p... View full abstract»

    A network management system (NMS) has been built using distributed object technology and a four-layered architecture with device model objects. This NetKeeper NMS, which is built on a distributed object platform, has improved scalability and fault tolerance, and can be customized easily. It can thus be used to manage enterprise networks, which consist of a huge number of multi-vendor network devic... 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»

  • Can CORBA fulfil data transfer requirements of industrial enterprises?

    Publication Year: 1997, Page(s):129 - 137

    The globalization of industrial enterprises leads to problems caused by the heterogeneity of hard- and software. To overcome these problems, distributed platforms can be used. Yet, much work remains to be done on distributed platforms before they actually can meet industrial needs. For example, there is no standardized mechanism for asynchronous data transfer and no possibility to transmit so-call... View full abstract»

    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»

    Issues of workflow systems adaptability and evolution capability are discussed from two perspectives, namely design and evolution of workflow systems from a continuous software engineering perspective as well as redesign and runtime on-the-fly modifications of workflow models from an application perspective. Special attention is paid to a suitable infrastructure support for designing more configur... View full abstract»

  • Virtual private resources. An approach for long-term binding of services

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (968 KB)

    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»

    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»

    Enterprise level QoS issues are discussed, from which QoS evolution paths are derived. Service level QoS issues are identified and they have been studied as apart of service quality issues in TINA service architecture. TINA stream binding and its role in the TINA QoS framework are presented. A soft guarantee of stream quality is proposed, which does not require strict resource reservation. Soft gu...

    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»

    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»

    One of the most important CORBA services defined by the OMG is the Object Transaction Service (OTS) which augments the CORBA object model with the notion of distributed transactions. The implementation design of the OTS is critical for the service to be really effective for applications. A good design suggests that the OTS should be part of the ORB (object request broker) itself rather than on top... View full abstract»

  • An implementation of CORBA's LifeCycle service

    Publication Year: 1997, Page(s):111 - 117
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (512 KB)

    CORBA enables objects to interact in a transparent manner according to location and heterogeneity. However, this kind of platforms lack mobility functions. That is why the author proposes a solution based on a generic implementation of CORBA's LifeCycle service. The mechanism relies on intermediary objects that are used to encapsulate mobility management View full abstract»

    The goal of enterprise modeling is to capture the structure and operations of a business as simply and directly as possible. The object-oriented approach to enterprise modeling allows us to capture the structure and operations of a business as a collection of interacting business objects. The enterprise model provides us with useful insights into the workings of a business and hence facilitates ex... View full abstract»

    This paper introduces an object-oriented approach to the integrated modeling of organizations, and their information systems in a distributed context. The approach is based on the OOram role modeling methodology concepts and tool. In the proposed approach organization modeling is done at the enterprise level of abstraction and both reverse and forward engineering are consistently supported. Distri... 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.

    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»

    Traditional systems development methodologies are not focused on the development of distributed systems. However, efforts to address these problems are going on within OMG, with the focus to standardise a meta-model for analysis and design methodologies. The initial submissions converged into a meta-model of Unified Modeling Language (UML), which is emerging as the standard from OMG. This meta-mod... 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»
