Oracle designed its database products to be flexible and configurable so they would operate on a variety of hardware platforms, and they succeeded--Oracle software runs on more than seventy computer platforms, from mainframes to PC networks to handheld PDAs. The secret to this flexibility lies in the software's initialization parameters, whose numerous settings can be configured for top performance in countless environments. On the downside, however, improper settings can slow a system down; even grind it to a halt. And with so many parameters--which change from version to version of Oracle software--it's challenging for Oracle administrators to keep in mind the characteristics and optimal settings for each parameter.The Oracle Initialization Parameters Pocket Reference provides the crucial information you need to make key adjustments to your Oracle database. This concise guide is a mix of invaluable performance tips and a quick reference to Oracle's initialization parameters. The book describes each initialization parameter, indicates what category it's in--from auditing to multi-threaded server MTS--and whether it can be modified dynamically via the ALTER SESSION or ALTER SYSTEM command.In addition to the details about parameter characteristics and settings, you'll find performance tips, such as how the various parameters interact, and what the most advantageous settings are for different configurations. No other reference focuses exclusively on these initialization parameters--an absolute must for anyone working with an Oracle database.Presented in a handy, easy-to-use format, the Oracle Initialization Parameters Pocket Reference is a welcome alternative for anyone who's struggled to memorize the best configuration settings or gone back and forth to online resources, trying to figure out what works. O'Reilly's Pocket References put the information you need close at hand where you need it most. This guide will keep your Oracle databases operating at peak performance.

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.
