For those database administrators intending to upgrade or those who need to know the new features that will affect the entire Oracle database world, this book relates all of the features of this new database. The complete details of the database's new features, including database management and administration enhancements, are discussed. Improvements and additions to security, architecture, Internet features, real application clusters, and performance are also detailed.
In an effort to provide foresight as systems grow and resources are stressed, this guidebook explains how one of the major causes of unplanned database outages is the failure to anticipate the effects of growth. The benchmark method detailed enables users to spot areas of pending problems before they cripple the database. This real-world approach ensures the user will be prepared for whatever the future brings to mission-critical databases.
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.
Targeted at Oracle professionals who need fast and accurate working examples of complex issues, Oracle In-focus books target specific areas of Oracle technology in a concise manner. Plenty of working code is provided without a lot of theory, allowing database managers to solve their problems quickly without reviewing data that they already know. All code scripts are available for instant download from a companion web site.
Covering all aspects of Oracle disk I/O tuning, this book explores disk performance, RAID management, Oracle data file performance, and Oracle data segment internals. Also explored is physical disk I/O, which includes disk device internals, detecting disk bottlenecks, disk organization techniques, and disk striping and disk load balancing. Highlighted are RAID and Oracle performance as well as techniques for effective use of RAID with Oracle.
As Oracle professionals are challenged to create SQL statements that will support thousands of concurrent executions with sub-second response time, this book’s timing is critical as tuning Oracle SQL has become the single most important skill of the Oracle professional. While not appropriate for the beginner, this book allows senior Oracle professionals to explore important internal mechanisms within Oracle and the powerful and complex internals of Oracle SQL execution.
There are three parts to tuning an Oracle database: data modeling, SQL code tuning and physical database configuration.
A data model contains tables and relationships between tables. Tuning a data model involves normalization and de-normalization. Different approaches are required depending on the application, such as OLTP or a Data Warehouse. Inappropriate database design can make SQL code impossible to tune. Poor data modeling can have a most profound effect on database performance since all SQL code is constructed from the data model.
With tools for gaining as many as 30 times the execution speed, this handbook educates database administrators on how to rewrite SQL into PL/SQL and how to use advanced Oracle bulk array processing techniques to achieve high performance. Ready-to-use tips for saving hardware costs by running applications at peak efficiencies are provided for senior Oracle DBAs and developers, and powerful PL/SQL techniques are outlined.
Your Oracle career starts here! Ideal for those new to Oracle technology, this officially authorized guide teaches new DBAs the essentials of keeping an Oracle database running at top performance. You’ll get coverage of application, instance, database, I/O, OS, and contention tuning.
