Principles of Transaction Processing is a comprehensive guide to developing applications, designing systems, and evaluating engineering products. The book provides detailed discussions of the internal workings of transaction processing systems, and it discusses how these systems work and how best to utilize them. It covers the architecture of Web Application Servers and transactional communication paradigms.The book is divided into 11 chapters, which cover the following: Overview of transaction processing application and system structureSoftware abstractions found in transaction processing systemsArchitecture of multitier applications and the functions of transactional middleware and database serversQueued transaction processing and its internals, with IBM's Websphere MQ and Oracle's Stream AQ as examplesBusiness process management and its mechanismsDescription of the two-phase locking function, B-tree locking and multigranularity locking used in SQL database systems and nested transaction lockingSystem recovery and its failuresTwo-phase commit protocolComparison between the tradeoffs of replicating servers versus replication resourcesTransactional middleware products and standardsFuture trends, such as cloud computing platforms, composing scalable systems using distributed computing components, the use of flash storage to replace disks and data streams from sensor devices as a source of transaction requests. The text meets the needs of systems professionals, such as IT application programmers who construct TP applications, application analysts, and product developers. The book will also be invaluable to students and novices in application programming. - Complete revision of the classic "non mathematical" transaction processing reference for systems professionals - Updated to focus on the needs of transaction processing via the Internet-- the main focus of business data processing investments, via web application servers, SOA, and important new TP standards - Retains the practical, non-mathematical, but thorough conceptual basis of the first edition

During recent years a great deal of progress has been made in performance modelling and evaluation of the Internet, towards the convergence of multi-service networks of diverging technologies, supported by internetworking and the evolution of diverse access and switching technologies. The 44 chapters presented in this handbook are revised invited works drawn from PhD courses held at recent HETNETs International Working Conferences on Performance Modelling and Evaluation of Heterogeneous Networks. They constitute essential introductory material preparing the reader for further research and development in the field of performance modelling, analysis and engineering of heterogeneous networks and of next and future generation Internets. The handbook aims to unify relevant material already known but dispersed in the literature, introduce the readers to unfamiliar and unexposed research areas and, generally, illustrate the diversity of research found in the high growth field of convergent heterogeneous networks and the Internet. The chapters have been broadly classified into 12 parts covering the following topics: Measurement Techniques; Traffic Modelling and Engineering; Queueing Systems and Networks; Analytic Methodologies; Simulation Techniques; Performance Evaluation Studies; Mobile, Wireless and Ad Hoc Networks, Optical Networks; QoS Metrics and Algorithms; All IP Convergence and Networking; Network Management and Services; and Overlay Networks.

Volume 1 of 4. The January and July issues of the Indian Army List contain not only the distribution of officers on the active list of the Army in India, including officers of British army regiments, battalions etc stationed in India, but are supplemented by the addition of Orders of Knighthood, Honours and Awards, including Foreign Orders, by the non-effective officer list and the War Services of officers of the Indian Army. Details of each officer include dates of birth (except for wartime commissioned officers), date of first commission, of appointment to the Indian Army and dates of promotion. Officers are grouped according to their rank and by seniority within that rank, and are again shown under their regiments/battalions. In the case of British units, their date of arrival in India is shown, and with Indian units their date of formation and changes in title since, plus details of the backgrounds of men recruited, e.g. Sikhs, Punjabis, Dogras, Rajputs, etc. This army list also includes all native Viceroy Commissioned Officers - Subadar Majors, Subadars and Jemadars - and their war services, Major HQs and their staffs, divisional and brigade commanders and their staffs, schools, colleges, Administrative Departments of the Army are all shown. Non-regular Indian Defence Force units such as 22nd Bengal and North-Western railway Battalion, and the Indian Army Reserve of Officers are all there, along with British Warrant Officers serving in departments of the Indian Army. In 1914 there were 116 Indian and 10 Gurkha Regiments, all with one battalion apart from the cavalry, 32 Indian and one Gurkha regiment had been formed and the majority of the original regiments had raised second and sometimes third battalions. This splendid four-volume work reflects the tremendous contribution made by the Indian Army to the Empire's war effort. A full index is included.

Papers in this book report on a wide variety of multicomputer applications, systems and architectures. They all have one aspect on common which is message passing multiprocessors. It includes research presentations of the T9000, TI C-40 and T8/i860-based multicomputers.

This book gives a detailed overview of SIP specific security issues and how to solve them While the standards and products for VoIP and SIP services have reached market maturity, security and regulatory aspects of such services are still being discussed. SIP itself specifies only a basic set of security mechanisms that cover a subset of possible security issues. In this book, the authors survey important aspects of securing SIP-based services. This encompasses a description of the problems themselves and the standards-based solutions for such problems. Where a standards-based solution has not been defined, the alternatives are discussed and the benefits and constraints of the different solutions are highlighted. Key Features: Will help the readers to understand the actual problems of using and developing VoIP services, and to distinguish between real problems and the general hype of VoIP security Discusses key aspects of SIP security including authentication, integrity, confidentiality, non-repudiation and signalling Assesses the real security issues facing users of SIP, and details the latest theoretical and practical solutions to SIP Security issues Covers secure SIP access, inter-provider secure communication, media security, security of the IMS infrastructures as well as VoIP services vulnerabilities and countermeasures against Denial-of-Service attacks and VoIP spam This book will be of interest to IT staff involved in deploying and developing VoIP, service users of SIP, network engineers, designers and managers. Advanced undergraduate and graduate students studying data/voice/multimedia communications as well as researchers in academia and industry will also find this book valuable.

This IBM® Redbooks® publication discusses the new IBM WebSphere® DataPower® Integration Appliance XI50 for zEnterpriseTM that bridges the gap between mainframe and distributed. The DataPower XI50z (a multifunctional appliance) within the zEnterprise BladeCenter® Extension (zBX) is managed with a single point of control, which can help to streamline operations and maintenance. The DataPower XI50z simplifies the translation of your existing formats to XML (hardware acceleration) for easier communication and connectivity. This book will help you install, tailor, and configure the new attributes for implementing a zEnterprise ensemble network. The zEnterprise System introduces internal virtual networks (VLANs) and additional networking attributes that need to be addressed. Also, we describe the planning considerations for the internal virtual networks and external networks. This book is for anyone who wants an understanding of the security on the zEnterprise that focuses on the usage of the XI50z Network Security Services. As you can expect from an IBM Redbooks publication, we provide several integration use cases that you are able to use immediately within a production environment, for example, the XI50z connecting with and using WebSphere MQ (WMQ), connecting with CICS®, connecting with IMSTM, and connecting with DB2®.
