描述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. . . . .Provides proven solutions to real-life Oracle performance problems . .Offers relevant background and theory to support

Monitoring System Performance,tabase for a specific period of time. Usually, when there are performance issues occurring within a database, it’s easy to know when the performance problems are occurring because database activity is “slow” during that given time frame. Knowing this time frame is the starting point to perform the analysis using the AWR information.
