Oracle Database Performance Tuning Guide is an aid for people responsible for the
operation, maintenance, and performance of Oracle. This book describes detailed
ways to enhance Oracle performance by writing and tuning SQL properly, using
performance tools, and optimizing instance performance. It also explains how to
create an initial database for good performance and includes performance-related
reference information. This book could be useful for database administrators,
application designers, and programmers.
This book covers everything you need to know to pass the OCP: Oracle8i
Performance and Tuning and OCP: Oracle8i Network Administration
exams. The first part of the book covers the most critical areas of database
performance tuning and how to follow and implement Oracle’s recommended
tuning methodology. The second part covers the topics of network
administration including configuring the necessary client and server components
of an Oracle network and helps you develop an understanding of the
Oracle 8i Net8 architecture....
Queries not running fast enough? Tired of the phone calls from frustrated users? Grant Fritchey’s book SQL Server 2012 Query Performance Tuning is the answer to your SQL Server query performance problems. The book is revised to cover the very latest in performance optimization features and techniques. It is current with SQL Server 2012. It provides the tools you need to approach your queries with performance in mind.
Oracle Database 11g 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....
"Offers hundreds of hints, tips, and tricks of the trade that can be useful to any DBA wanting to achieve maximum performance of Oracle applications. No Oracle library would be complete without this book." --Ken (Dr. DBA) Jacobs, Vice President of Product Strategy for Server Technologies, Oracle Corporation
"Rich is the first and last stop for Oracle Database technology and performance tuning. His knowledge is a vital tool that you need to successfully negotiate the waters of Oracle database development." --Mike Frey, Principal Architect, Navteq
Written by a team of expert SQL users, this comprehensive resource approaches performance tuning from a new perspective by showing you a methodical scientific approach to diagnose performance problems. The book first walks you through how to discover bottlenecks when something is wrong and you’ll then learn how to identify and remove the problems that are causing poor performance. You’ll discover preventive measures you can take to try to avoid a performance problem entirely and you’ll learn how to achieve better performance....
The books in O'Reilly's Oracle series are authoritative -- they tell the whole story about complex topics, ranging from performance tuning to the use of packages in PL/SQL to new technologies like Power Objects. And they're independent; they're alternatives for readers who need to know how products and features really work. They're packed with real-world advice and techniques from practitioners in the field, and they come with disks containing code you can use immediately in your own applications.
Performance has been an important issue with Java™ since the first version hit the Web years ago.
Making those first interpreted programs run fast enough was a huge challenge for many developers.
Since then, Java performance has improved enormously, and any Java program can now be made to
run fast enough provided you avoid the main performance pitfalls.
This book provides all the details a developer needs to performance-tune any type of Java program.
After completing this lesson, you should be able to do the following:
Define the roles associated with the database tuning process
Describe the dependencies between tuning in different development phases
Describe service level agreements
Identify tuning goals
Identify common tuning problems
Employ tuning activities during developmentand production
Balance performance and safety trade-offs
Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25% performance increase.
This book is about tuning Oracle databases. Three areas of Oracle Database tuning are data model tuning, SQL code tuning, and physical and configuration tuning. The author began his career as an applications developer, not as a systems or network administrator. As a result, this book is written from an applications rather than an operating system perspective.
You can enhance Oracle performance by adjusting database applications, the database
itself, and the operating system. Making such adjustments is known as tuning.
Proper tuning of Oracle provides the best possible database performance for your
specific application and hardware configuration.
Note: Oracle8 Tuning contains information that describes the features and functionality
of the Oracle8 and the Oracle8 Enterprise Edition products. Oracle8 and
Oracle8 Enterprise Edition have the same basic features.
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 11g Performance Tuning Recipes delivers.
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.
