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!

Yocto for Raspberry Pi. Create unique and amazing projects by using the powerful combination of Yocto and Raspberry Pi

TEXIER Pierre-Jean, Petter Mabäcker

The Yocto Project is a Linux Foundation workgroup, which produces tools (SDK) and processes (configuration, compilation, installation) that will enable the creation of Linux distributions for embedded software, independent of the architecture of embedded software (Raspberry Pi, i.MX6, and so on). It is a powerful build system that allows you to master your personal or professional development.This book presents you with the configuration of the Yocto Framework for the Raspberry Pi, allowing you to create amazing and innovative projects using the Yocto/OpenEmbedded eco-system. It starts with the basic introduction of Yocto's build system, and takes you through the setup and deployment steps for Yocto. It then helps you to develop an understanding of Bitbake (the task scheduler), and learn how to create a basic recipe through a GPIO application example. You can then explore the different types of Yocto recipe elements (LICENSE, FILES, SRC_URI, and so on). Next, you will learn how to customize existing recipes in Yocto/OE layers and add layers to your custom environment (qt5 for example).
