WS-BPEL 2.0 for SOA Composite Applications with Oracle SOA Suite 11g. Define, model, implement, and monitor real-world BPEL business processes with SOA powered BPM

Matjaz B. Juric, Marcel Krizevnik, Matjaz B Juric

Business Process Execution Language (BPEL, aka WS-BPEL) has become the de-facto standard for orchestrating services in SOA composite applications. BPEL reduces the gap between business requirements and applications and allows for better alignment between business processes and underlying IT architecture. BPEL is for SOA what SQL is for databases. Therefore learning BPEL is essential for the successful adoption of SOA or the development of composite applications. Although BPEL looks simple at first sight, it hides its large potential and has many interesting and advanced features. If you can get familiar with these features - you can maximize the value of SOA.This book provides a comprehensive and detailed coverage of BPEL, one of the centerpieces of SOA. It covers basic and advanced features of BPEL 2.0 and provides several real-world examples. In addition to BPEL specification the book provides comprehensive coverage of BPEL support in Oracle SOA Suite 11g, including security, transactions, human workflow, process monitoring, automatic generation of BPEL from process models, dynamic processes, and more.This book starts with an introduction to BPEL, its role with regard to SOA and the process-oriented approach to SOA. The authors give short descriptions of the most important SOA platforms and BPEL servers—the run time environments for the execution of business processes specified in BPEL—and compare BPEL to other business process languages. The book will then move on to explain core concepts such as invoking services, synchronous and asynchronous processes, partner links, role of WSDL, variables, flows, and more.Moving ahead you will become familiar with fault handling, transaction management and compensation handling, scopes, events and event handlers, concurrent activities and links. The authors also discuss the business process lifecycle, correlation of messages, dynamic partner links, abstract business processes and mapping from BPMN to BPEL.The book presents in detail, how to use BPEL with Oracle SOA Suite 11g PS2. It explains the development of BPEL and SCA assemblies, and demonstrates different approaches with some practical examples. It addresses security, transaction handling, and human workflow. Then, the book addresses entity variables, notification services, fault management framework, and business events in BPEL. It provides exhaustive coverage of monitoring BPEL processes and developing dashboards with Oracle BAM. It explains how to use BPEL processes with Oracle Service Bus and Oracle Service Registry. Using examples, the book also demonstrates how to transform business process models in BPMN (using Business Modeler) to BPEL, how to achieve round-tripping using BPA Suite and BPM Suite, and how to use Oracle Enterprise Repository to govern BPEL processes. The book also covers the complete BPM lifecycle from modeling through implementation, execution, monitoring, and optimization and presents advanced, real-world examples.

Wydajność i optymalizacja kodu. Istota dynamiki działania oprogramowania

Richard L. Sites

Mimo że dysponujemy coraz szybszym i wydajniejszym sprzętem, oprogramowaniu wciąż stawia się wyśrubowane wymagania: musi działać błyskawicznie i niezawodnie. Nieraz od jakości pracy systemu zależy bardzo dużo, nawet bezpieczeństwo i życie człowieka. Eliminacja źródłowych przyczyn problemów wydajnościowych jest jednak niezwykle trudnym zadaniem. Wymaga wiedzy o działaniu sprzętu, interakcjach między komponentami systemu, a także wysokiej klasy umiejętności programistycznych. Ta książka jest przeznaczona dla programistów i osób zaawansowanych w nauce programowania. Dzięki niej nauczysz się uwzględniać w projektach narzędzia do obserwacji pracy kodu i analizować uzyskane dzięki nim dane o wydajności. Dowiesz się też, jak na podstawie takiego wnioskowania uzyskiwać znaczną poprawę w szybkości przetwarzania powolnych operacji. Prezentowane treści zilustrowano przykładami i ćwiczeniami w języku C lub C++ w systemie Linux. Materiał zawarty w książce to trzy główne zagadnienia: pomiary, obserwacje, a także wnioskowanie i nanoszenie poprawek w kodzie. Wartościową częścią książki jest omówienie procesu budowy niskokosztowego narzędzia do obserwacji KUtrace i jego zastosowania we wdrażaniu wyrafinowanych rozwiązań programistycznych. W ten sposób można u źródła usuwać przyczyny problemów z wydajnością kodu. Najciekawsze zagadnienia: problemy sprzętowe: procesory, pamięci, dyski twarde, nośniki SSD i sieci korygowanie kodu wolno działającego programu przydatne mechanizmy monitorowania pracy kodu analiza danych dotyczących wydajności identyfikacja problemów, takich jak wykonywanie zbyt wielu instrukcji, powolne wykonywanie instrukcji, oczekiwanie na zasoby i blokady programowe Kod eksperta: tu każdy bit ma znaczenie!

XNA Game Studio enables hobbyists and independent game developers to easily create video games. It gives you the power to bring your creations to life on Windows, the Xbox 360, the Zune, and the Windows Phone platforms. But before you give life to your creativity with XNA, you need to gain a solid understanding of some game development concepts.This book covers both the concepts and the implementations necessary to get you started on bringing your own creations to life with XNA. It details the creation of four games, all in different styles, from start to finish using the Microsoft XNA Framework, including a puzzler, space shooter, multi-axis shoot-'em-up, and a jump-and-run platform game. Each game introduces new concepts and techniques to build a solid foundation for your own ideas and creativity. Beginning with the basics of drawing images to the screen, the book then incrementally introduces sprite animation, particles, sound effects, tile-based maps, and path finding. It then explores combining XNA with Windows Forms to build an interactive map editor, and builds a platform-style game using the editor-generated maps. Finally, the book covers the considerations necessary for deploying your games to the Xbox 360 platform.By the end of the book, you will have a solid foundation of game development concepts and techniques as well as working sample games to extend and innovate upon.

Zabbix 1.8 Network Monitoring. Monitor your network hardware, servers, and web performance effectively and efficiently

Rihards Olups

Imagine you're celebrating the start of the weekend with Friday-night drinks with a few friends. And then suddenly your phone rings -- one of the servers you administer has gone down, and it needs to be back up before tomorrow morning. So you drag yourself back to the office, only to discover that some log files have been growing more than usual over the past few weeks and have filled up the hard drive. While the scenario above is very simplistic, something similar has happened to most IT workers at one or another point in their careers. To avoid such situations this book will teach you to monitor your network hardware, servers, and web performance using Zabbix- an open source system monitoring and reporting solution.The versatility of Zabbix allows monitoring virtually anything, but getting started with the new concepts can take some time. This book will take you through the most common tasks in a hands-on, step by step manner.Zabbix is a very flexible IT monitoring suite, but not every part of it is immediately clear to new users. Following the instructions in this book should allow you to set up monitoring of various metrics on various devices, including Linux and Windows machines, SNMP devices, IPMI enabled server,s and other network attached equipment. You will learn to define conditions – such a temperature being too high or service being down – and act upon them by notifying user by email, SMS, or even restarting service. You will learn to visualize the gathered data with graphs and the various tips and tricks that are provided will help to use Zabbix more efficiently and avoid common pitfalls.This book covers setting up Zabbix from the scratch and gradually introduces basic components of Zabbix, moving to more advanced topics later. Book's scope is based on the author's experience of working with Zabbix for many years, as well as on the questions users have asked on the Zabbix IRC channel and forums.
