“…Based on this assumption we built tools to extract configuration information from the application files and then to browse and query the metadata which has been stored in the MDR. These tools are in turn used by a systems administrator to help manage the distributed application [3].…”

In the not too distant past, the amount of online data available to general users was relatively small. Most of the online data was maintained in organizations' database management systems and accessible only through the interfaces provided by those systems. The popularity of the Internet, in particular, has meant that there is now an abundance of online data available to users in the form of Web pages and files. This data, however, is maintained in passive data sources, that is sources that do not provide facilities to search or query their data. The data must be queried and examined using applications such as browsers and search engines. In this paper, we explore an approach to querying passive data sources based on the extraction, and subsequent exploitation, of metadata from the data sources. We describe two situations in which this approach has been used, evaluate the approach and draw some general conclusions.

ABSTRACTViruses remain a significant threat to modern networked computer systems. Despite the best efforts of those who develop anti-virus systems, new viruses and new types of virus that are not dealt with by existing protection schemes appear regularly. In addition, the rate at which a virus can spread has risen dramatically with the increase in connectivity. Defenses against infections by known viruses rely at present on immunization yet, for a variety of reasons, immunization is often only effective on a subset of the nodes in a network and many nodes remain unprotected. Little is known about either the way in which a viral infection proceeds in general or the way that immunization affects the infection process. In this paper we present the results of a simulation study of the way in which virus infections propagate through certain types of network and of the effect that partial immunization has on the infection. The key result is that relatively low levels of immunization can slow an infection significantly.

“…Our architecture is open and can be easily integrated with other management solutions. Our prototype systems have been integrated easily with other management solutions we have developed, OSI-compliant management solutions, as well as the work of other universities under the MANagement of Distributed Applications and Systems (MANDAS) project (Bauer et al, 1997). This integration was simpli®ed as we only needed to specialize coordinators to communicate with the various management systems, while other instrumentation components remained unchanged.…”

The goal of a management system in a distributed computing environment as t o provide a centralized and coordinated view of an otherwise distributed and heterogeneous collection of hardware and software resources. Management systems monitor, analyse and control network resources, system resources, and distributed application programs.Many organizations currently depend on missioncritical distributed applications, a trend that will increase as software engineering tools emerge that make it easier to construct distributed applications. We believe that manageability must be built in t o distributed applications from the beginning rather than added in an ad hoc fashion after they have been developed. Just as designing software for usability, testability and maintenance are being addressed an the development process, so must designing for manageability.Applacataon manageabalaty as a research assue of partacular anterest t o us.
