This book investigates how transactions can be integrated with concurrent object-oriented programming, and how transactions can be made available to an application programmer at the programming language level. The book gives a detailed overview of existing transaction models, and analyzes their suitability for concurrent programming languages. A new transaction model named "Open Multithreaded Transactions" is presented. It provides features for controlling and structuring not only access to objects, as usual in transaction systems, but also threads taking part in transactions. Integration with exception handling makes open multithreaded transactions ideal building blocks for fault-tolerant applications. The book also describes the design of an object-oriented framework providing the necessary run-time support for open multithreaded transactions. Procedural, object-oriented and aspect-oriented interfaces for the application programmer are presented. Programming examples include code in Ada, Java and AspectJ.
This paper presents a framework called OPTIMA (OPen Transaction Integration
for Multithreaded Applications) that ... that provides support for open multithreaded transactions; section 5 presents an example program and the last

The Sixth International Conference on Reliable Software Technologies, Ada- Europe 2001, took place in Leuven, Belgium, May 14-18, 2001. It was sponsored by Ada-Europe, the European federation of national Ada societies, in cooperation with ACM SIGAda, and it was organized by members of the K.U. Leuven and Ada- Belgium. This was the 21st consecutive year of Ada-Europe conferences and the sixth year of the conference focusing on the area of reliable software technologies. The use of software components in embedded systems is almost ubiquitous: planes fly by wire, train signalling systems are now computer based, mobile phones are digital devices, and biological, chemical, and manufacturing plants are controlled by software, to name only a few examples. Also other, non-embedded, mission-critical systems depend more and more upon software. For these products and processes, reliability is a key success factor, and often a safety-critical hard requirement. It is well known and has often been experienced that quality cannot be added to software as a mere afterthought. This also holds for reliability. Moreover, the reliability of a system is not due to and cannot be built upon a single technology. A wide range of approaches is needed, the most difficult issue being their purposeful integration. Goals of reliability must be precisely defined and included in the requirements, the development process must be controlled to achieve these goals, and sound development methods must be used to fulfill these non-functional requirements.

missions in fact also treat an envisaged mutual impact among them. As for the 2002 edition in Irvine, the organizers wanted to stimulate this cross-pollination with a program of shared famous keynote speakers (this year we got Sycara, - ble, Soley and Mylopoulos!), and encouraged multiple attendance by providing authors with free access to another conference or workshop of their choice. We received an even larger number of submissions than last year for the three conferences (360 in total) and the workshops (170 in total). Not only can we therefore again claim a measurable success in attracting a representative volume of scienti?c papers, but such a harvest allowed the program committees of course to compose a high-quality cross-section of worldwide research in the areas covered. In spite of the increased number of submissions, the Program Chairs of the three main conferences decided to accept only approximately the same number of papers for presentation and publication as in 2002 (i. e. , around 1 paper out of every 4–5 submitted). For the workshops, the acceptance rate was about 1 in 2. Also for this reason, we decided to separate the proceedings into two volumes with their own titles, and we are grateful to Springer-Verlag for their collaboration in producing these two books. The reviewing process by the respective program committees was very professional and each paper in the main conferences was reviewed by at least three referees.

In this technological era, failure to address application-layer fault-tolerance, a key ingredient to crafting truly dependable computer services, leaves the door open to unfortunate consequences in quality of service.""Application-Layer Fault-Tolerance Protocols"" increases awareness of the need for application-layer fault-tolerance (ALFT) through introduction of problems and qualitative analysis of solutions. A necessary read for researchers, practitioners, and students in dependability engineering, this book collects emerging research to offer a systematic, critical organization of the current knowledge in ALFT.

Here's one of the singular references providing on-the-mark coverage of application development based on thhe Component Object Model (COM) and Microsoft Transaction Server (MTS). DESIGNING COMPONENT-BASED APPLICATIONS demonstrates the principles of effective COM-driven design and MTS deployment through in-depth examination of Island Hopper, a joint project of the Microsoft COM and Microsoft Visual Studio design teams. This full-featured enterprise application was built using a practical set of development guidelines field-tested by Microsoft consultants on a variety of 3-2-1 projects (3 tiers, 2 developers, 1month). As you focus on individual facets of the model application, you're also learning how to apply this proven methodology to quickly design, test, debug, and deploy your own multitier, COM-based programs.

Advances in computer networking have allowed computer systems across the world to be interconnected. Open Distributed Processing (ODP) systems are those that support heterogenous distributed applications both within and between autonomous organizations. Many challenges must be overcome before ODP systems can be fully realized. This book describes the recent advances in the theory and practice of developing, deploying and managing open distributed systems. Applications of these systems include but are not limited to telecommunication, medical and large scale transaction processing and electronic commerce systems. All of these are currently developed on distributed platforms. For anybody working in industry or research in this field, Open Distributed Processing and Distributed Platforms will prove an invaluable text.

Foundations of Multithreaded, Parallel, and Distributed Programming covers, and then applies, the core concepts and techniques needed for an introductory course in this subject. Its emphasis is on the practice and application of parallel systems, using real-world examples throughout. Greg Andrews teaches the fundamental concepts of multithreaded, parallel and distributed computing and relates them to the implementation and performance processes. He presents the appropriate breadth of topics and supports these discussions with an emphasis on performance. Features Emphasizes how to solve problems, with correctness the primary concern and performance an important, but secondary, concern Includes a number of case studies which cover such topics as pthreads, MPI, and OpenMP libraries, as well as programming languages like Java, Ada, high performance Fortran, Linda, Occam, and SR Provides examples using Java syntax and discusses how Java deals with monitors, sockets, and remote method invocation Covers current programming techniques such as semaphores, locks, barriers, monitors, message passing, and remote invocation Concrete examples are executed with complete programs, both shared and distributed Sample applications include scientific computing and distributed systems 0201357526B04062001
