There are many options these days for measuring and monitoring Oracle(r) Database application performance. This book is about the one that endures as the best foundation there is for understanding Oracle performance: the Oracle extended SQL trace feature. This book is the course book for the 1-day "Mastering Oracle Trace Data" course taught by the author, Cary Millsap. It is not a book about discarding your Oracle fixed views or your monitoring tools that poll them. It is a book about how to look at Oracle performance another way, a way that has worked extraordinarily well for many of us. It's about new ways of thinking about performance using new tools for understanding aspects of your applications that you've never understood before. Contents include: Part one - A coherent framework for understanding all aspects of performance beginning with foundational definitions, case studies illustrating the use of Oracle extended SQL trace data in the performance problem and repair context, detailed descriptions of how to create and obtain extended SQL trace data in different languages and application contexts, detailed explanations of how to understand the story that the trace data is trying to tell you, detailed reference material about Oracle timing measurements and how to use them. Part two - Over 100 pages of worked examples (case studies) illustrating how to analyze and solve performance problems with Oracle-based applications, using the Method R Profiler, Method R Tools, and Method R Trace commercial software packages. Part three - A perspective on why trace files are still important in this modern age of ASH and AWR, and a list of explanations by dozens of Oracle professionals about why they use trace data today.

This book introduces a relatively new approach to mastering one’s Oracle SQL skills. This book will teach you how to leverage your existing Oracle SQL knowledge as well as how you can benefit from a variety of SQL tricks and techniques we present thereafter. This is a text book rather than a reference, and it aims to teach you how to become a better SQL specialist. Even though the recommendations found in this book may be applied to a variety of SQL flavors, Oracle SQL is the main subject of this book. Our goal was not to impress you with clever tricks and sophisticated techniques, but rather give you a roadmap to excellence in writing Oracle SQL queries. No doubt, this book presents tricks and classy approaches, which still serve the main goal – to let you master your Oracle SQL skills.

The vast majority of Oracle SQL books discuss some syntax, provide the barest rudiments of using Oracle SQL, and perhaps include a few simple examples. It might be enough to pass a survey course, or give you some buzz words to drop in conversation with real Oracle DBAs. But if you use Oracle SQL on a regular basis, you want much more. You want to access the full power of SQL to write queries in an Oracle environment. You want a solid understanding of what's possible with Oracle SQL, creative techniques for writing effective and accurate queries, and the practical, hands-on information that leads to true mastery of the language. Simply put, you want useful, expert best practices that can be put to work immediately, not just non-vendor specific overview or theory.Updated to cover the latest version of Oracle, Oracle 10g, this edition of the highly regarded Mastering Oracle SQL has a stronger focus on technique and on Oracle's implementation of SQL than any other book on the market. It covers Oracle s vast library of built-in functions, the full range of Oracle SQL query-writing features, regular expression support, new aggregate and analytic functions, subqueries in the SELECT and WITH clauses, multiset union operators, enhanced support for hierarchical queries: leaf and loop detection, and the CONNECT_BY_ROOT operator, new partitioning methods (some introduced in Oracle9i Release 2), and the native XML datatype, XMLType.Mastering Oracle SQL, 2nd Edition fills the gap between the sometimes spotty vendor documentation, and other books on SQL that just don't explore the full depth of what is possible with Oracle-specific SQL. For those who want to harness the untapped (and often overlooked) power of Oracle SQL, this essential guide for putting Oracle SQL to work will prove invaluable.

Exploring the major features and packages of Go, along with its types and data-structures, enabling the reader to write threadsafe, concurrent cloud, and network applications Key Features Not your typical introduction to the Golang programming language Exploring Golang cradle to grave, completes the developer’s Golang education A thorough exploration into the core libraries and Golang features, that usually are taken for granted In depth explanation, detailing the rationale behind composite data types, Golang concurrency, and the Golang networking library Book Description The Go programming language, often referred to as Golang (albeit wrongly), is really making strides, with some masterclass developments, architected by the greatest programming minds. Tobias Lutke, CEO of Shopify, recently quoted as saying “Go will be the server language of the future”, powerful words, with much ambition. Go programmers are in high demand, but more controversially, Go takes the stage, where C and Unix programmers previously led the way. The growth of the Go language has seen it become the means by which systems, networking, web, and cloud applications are implemented. Comfortable with syntax, you’ll benefit by mastering the use of the libraries and utilise its features, speed, and efficiency, for which the Go ecology is justly famous. You already know a little Go syntax and you’ve written some small projects, most Go programmers face the difficulty of having to integrate their Golang skills with production code. Typical introductions to Go programming, often stop short of this transition, the author continue on, showing you just how to tackle this. Offering a compendium of Go, the book begins with an account of how Go has been implemented, also, the reader will benefit from a dedicated chapter, an in-depth account of concurrency, systems and network programming, imperative for modern-day native cloud development. What you will learn Understand the design choices of Golang syntax Know enough Go internals to be able to optimize Golang code Appreciate concurrency models available in Golang Understand the interplay of systems and networking code Write server-level code that plays well in all environments Understand the context and appropriate use of Go data types and data structures Who this book is for This book is for Golang programmers. You should have previously read an introductory book on Go, or to have worked through the Tour of Go or an equivalent online course. This book will definitely help to remember the basic concepts of concurrency, but network programming will be explained. A certain amount of previous coding and production experience would be helpful.

House framing can be an intimidating challenge. Thousands of pieces of wood must be cut to precise dimensions, according to a set of plans. Accurate and safe assembly is critical as the house must support the weight of building materials, equipment, appliances and people - there's simply no room for error. And yet, this comprehensive, accessible and highly visual book walks readers through this complicated process with ease. It's all here, from using the right tools and framing a first-floor deck; to building stairs, roofs and dormers; and installing exterior trim. Former Fine Homebuilding editor and builder Roe Osborn doesn't leave out the hard parts; he simply makes them understandable.
