| dba_hist_active_sess_history 19c: Oracle Database 12c Performance Tuning Recipes Sam Alapati, Darl Kuhn, Bill Padfield, 2014-01-21 Performance problems are rarely problems per se. They are more often crises during which you’re pressured for results by a manager standing outside your cubicle while your phone rings with queries from the help desk. You won’t have the time for a leisurely perusal of the manuals, nor to lean back and read a book on theory. What you need in that situation is a book of solutions, and solutions are precisely what Oracle Database 12c Performance Tuning Recipes delivers. Oracle Database 12c Performance Tuning Recipes is a ready reference for database administrators in need of immediate help with performance issues relating to Oracle Database. The book takes an example-based approach, wherein each chapter covers a specific problem domain. Within each chapter are recipes, showing by example how to perform common tasks in that chapter’s domain. Solutions in the recipes are backed by clear explanations of background and theory from the author team. Whatever the task, if it’s performance-related, you’ll probably find a recipe and a solution in this book.

| dba_hist_active_sess_history 19c: Optimizing Oracle Performance Cary Millsap, Jeff Holt, 2003-09-16 Oracle system performance inefficiencies often go undetected for months or even years--even under intense scrutiny--because traditional Oracle performance analysis methods and tools are fundamentally flawed. They're unreliable and inefficient.Oracle DBAs and developers are all too familiar with the outlay of time and resources, blown budgets, missed deadlines, and marginally effective performance fiddling that is commonplace with traditional methods of Oracle performance tuning. In this crucial book, Cary Millsap, former VP of Oracle's System Performance Group, clearly and concisely explains how to use Oracle's response time statistics to diagnose and repair performance problems. Cary also shows how queueing theory can be applied to response time statistics to predict the impact of upgrades and other system changes.Optimizing Oracle Performance eliminates the time-consuming, trial-and-error guesswork inherent in most conventional approaches to tuning. You can determine exactly where a system's performance problem is, and with equal importance, where it is not, in just a few minutes--even if the problem is several years old.Optimizing Oracle Performance cuts a path through the complexity of current tuning methods, and streamlines an approach that focuses on optimization techniques that any DBA can use quickly and successfully to make noticeable--even dramatic--improvements.For example, the one thing database users care most about is response time. Naturally, DBAs focus much of their time and effort towards improving response time. But it is entirely too easy to spend hundreds of hours to improve important system metrics such as hit ratios, average latencies, and wait times, only to find users are unable to perceive the difference. And an expensive hardware upgrade may not help either.It doesn't have to be that way. Technological advances have added impact, efficiency, measurability, predictive capacity, reliability, speed, and practicality to the science of Oracle performance optimization. Optimizing Oracle Performance shows you how to slash the frustration and expense associated with unraveling the true root cause of any type of performance problem, and reliably predict future performance.The price of this essential book will be paid back in hours saved the first time its methods are used. |

| dba_hist_active_sess_history 19c: SQL Tuning Dan Tow, 2003-11-19 A poorly performing database application not only costs users time, but also has an impact on other applications running on the same computer or the same network. SQL Tuning provides an essential next step for SQL developers and database administrators who want to extend their SQL tuning expertise and get the most from their database applications.There are two basic issues to focus on when tuning SQL: how to find and interpret the execution plan of an SQL statement and how to change SQL to get a specific alternate execution plan. SQL Tuning provides answers to these questions and addresses a third issue that's even more important: how to find the optimal execution plan for the query to use.Author Dan Tow outlines a timesaving method he's developed for finding the optimum execution plan--rapidly and systematically--regardless of the complexity of the SQL or the database platform being used. You'll learn how to understand and control SQL execution plans and how to diagram SQL queries to deduce the best execution plan for a query. Key chapters in the book include exercises to reinforce the concepts you've learned. SQL Tuning concludes by addressing special concerns and unique solutions to unsolvable problems.Whether you are a programmer who develops SQL-based applications or a database administrator or other who troubleshoots poorly tuned applications, SQL Tuning will arm you with a reliable and deterministic method for tuning your SQL queries to gain optimal performance. |
| dba_hist_active_sess_history 19c: Be Mine Tonight Kathryn Smith, 2009-10-13 I am called Chapel . . . For nearly six centuries I have roamed the night, a mortal man no longer. Would that I could undo the past -- when I entered the sanctuary of the Knights Templar to wrest from them the Holy Grail, only to discover the chalice I raised to my lips was not the sacred relic but a hellish cup of damnation. Now I shun the day and all things human, driven by an ungodly thirst. And yet... Never have I known a maiden the like of Prudence Ryland, whose beauty and spirit awaken a heart I feared long cold and dead. But her young life is slipping away, and she also seeks the deliverance of the Grail -- unaware that the cost of her search could be her soul. I must help Prudence, for in six hundred years, no other woman has stirred my passions so. But dare I tender to my beloved that which she most desires -- the sensuous gift of forever that is both rapture and a curse: my immortal kiss? |

| dba_hist_active_sess_history 19c: Oracle SQL High-performance Tuning Guy Harrison, Raymond Aron, 2001 Canada was young during the First World War, and with as many as 20,000 underage soldiers leaving their homes to join the war effort, the country's army was, too. Jim, at 17, was one of them, and he penned countless letters home. But these weren't the writings of an ordinary boy. They were the letters of a lad who left a small farming community for the city on July 15, 1915, a boy who volunteered to serve with the 79th Queen's Own Cameron Highlanders. Jim's letters home gloss over the horrors of war, focusing instead on issues of the home front: of harvesting, training the horses, and the price of hogs. Rarely do these letters, especially those to his mother and father, mention the mud and rats, the lice and stench of the trenches, or the night duty of cutting barbed wire in no man's land. For 95 years his letters remained in a shoebox decorated by his mother. Jim was just 18 when he was wounded and died during the Battle of the Somme. Hold the Oxo! tells the story that lies between the lines of his letters, filling in the historical context and helping us to understand what it was like to be Jim. |

| dba_hist_active_sess_history 19c: The Art of SQL Stephane Faroult, Peter Robson, 2006-03-10 For all the buzz about trendy IT techniques, data processing is still at the core of our systems, especially now that enterprises all over the world are confronted with exploding volumes of data. Database performance has become a major headache, and most IT departments believe that developers should provide simple SQL code to solve immediate problems and let DBAs tune any bad SQL later. In The Art of SQL, author and SQL expert Stephane Faroult argues that this safe approach only leads to disaster. His insightful book, named after Art of War by Sun Tzu, contends that writing quick inefficient code is sweeping the dirt under the rug. SQL code may run for 5 to 10 years, surviving several major releases of the database management system and on several generations of hardware. The code must be fast and sound from the start, and that requires a firm understanding of SQL and relational theory. The Art of SQL offers best practices that teach experienced SQL users to focus on strategy rather than specifics. Faroult's approach takes a page from Sun Tzu's classic treatise by viewing database design as a military campaign. You need knowledge, skills, and talent. Talent can't be taught, but every strategist from Sun Tzu to modern-day generals believed that it can be nurtured through the experience of others. They passed on their experience acquired in the field through basic principles that served as guiding stars amid the sound and fury of battle. This is what Faroult does with SQL. Like a successful battle plan, good architectural choices are based on contingencies. What if the volume of this or that table increases unexpectedly? What if, following a merger, the number of users doubles? What if you want to keep several years of data online? Faroult's way of looking at SQL performance may be unconventional and unique, but he's deadly serious about writing good SQL and using SQL well. The Art of SQL is not a cookbook, listing problems and giving recipes. The aim is to get you-and your manager-to raise good questions. |

| dba_hist_active_sess_history 19c: Twentieth Century Borrowings from French to English Julia Landmann, 2013-01-16 French has long been the donor language par excellence in the history of English. French has contributed to the English vocabulary in the form of new words since before the Norman Conquest. The French influence on the English lexicon represents the focus of linguistic concern in a considerable number of investigations of the language and its development. Yet French borrowings which have recently been adopted into English have as yet figured little if at all in such studies. The present study sets out to shed light on the French impact on English in the recent past. The results presented in this book are based on a corpus of 1677 twentieth-century French borrowings collected from the Oxford English Dictionary Online. On the basis of their meanings, the words under consideration have been assigned to different subject fields in order to give a tour d’horizon of the manifold areas and spheres of life enriched by French in recent times. The first part of the present investigation concentrates on the phonological and orthographical reception of the various borrowings. The focus of this study is on the semantic development of the French borrowings in comparison to their sources in the donor language. Emphasis has been placed upon analysing whether a particular meaning a borrowing assumes after its first attested use is taken over from French, or whether it represents an independent semantic change within English. |
