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 anyonewho'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.

What You'll Learn Perform threat analysis Implement access level control and data encryption Avoid non-reputability by implementing comprehensive auditing Use security metadata to ensure your security policies are enforced Mitigate the risk of credentials being stolen Put countermeasures in place against common forms of attack Who This Book Is For Database administrators who need to understand and counteract the threat of attacks against their company's data, and useful for SQL developers and architects

Master SQL Server's Concurrency Model so you can implement high-throughput systems that deliver transactional consistency to your application customers. This book explains how to troubleshoot and address blocking problems and deadlocks, and write code and design database schemas to minimize concurrency issues in the systems you develop. SQL Server's Concurrency Model is one of the least understood parts of the SQL Server Database Engine. Almost every SQL Server system experiences hard-to-explain concurrency and blocking issues, and it can be extremely confusing to solve those issues without a base of knowledge in the internals of the Engine. While confusing from the outside, the SQL Server Concurrency Model is based on several well-defined principles that are covered in this book. Understanding the internals surrounding SQL Server's Concurrency Model helps you build high-throughput systems in multi-user environments. This book guides you through the Concurrency Model and elaborates how SQL Server supports transactional consistency in the databases. The book covers all versions of SQL Server, including Microsoft Azure SQL Database, and it includes coverage of new technologies such as In-Memory OLTP and Columnstore Indexes. What You'll Learn Know how transaction isolation levels affect locking behavior and concurrency Troubleshoot and address blocking issues and deadlocks Provide required data consistency while minimizing concurrency issues Design efficient transaction strategies that lead to scalable code Reduce concurrency problems through good schema design Understand concurrency models for In-Memory OLTP and Columnstore Indexes Reduce blocking during index maintenance, batch data load, and similar tasks Who This Book Is For SQL Server developers, database administrators, and application architects who are developing highly-concurrent applications. The book is for anyone interested in the technical aspects of creating and troubleshooting high-throughput systems that respond swiftly to user requests.
