Know how locks work in MySQL and how they relate to transactions. This book explains the major role that locks play in database systems, showing how locks are essential in allowing high-concurrency workloads. You will learn about lock access levels and lock granularities from the user level as well as table locks to record and gap locks. Most importantly, the book covers troubleshooting techniques when locking becomes a pain point. Several of the lock types in MySQL have a duration of a transaction. For this reason, it is important to understand how transactions work. This book covers the basics of transactions as well as transaction isolation levels and how they affect locking. The book is meant to be your go-to resource for solving locking contention and similar problems in high-performance MySQL database applications. Detecting locking issues when they occur is the first key to resolving such issues. MySQL Concurrency provides techniques for detecting locking issues such as contention. The book shows how to analyze locks that are causing contention to see why those locks are in place. A collection of six comprehensive case studies combine locking and transactional theory with realistic lock conflicts. The case studies walk you through the symptoms to look for in order to identify which issue you are facing, the cause of the conflict, its analysis, solution, and how to prevent the issue in the future. What You Will Learn Understand which lock types exist in MySQL and how they are used Choose the best transaction isolation level for a given transaction Detect and analyze lock contention when it occurs Reduce locking issues in your applications Resolve deadlocks between transactions Resolve InnoDB record-level locking issues Resolve issues from metadata and schema locks Who This Book Is For Database administrators and SQL developers who are familiar with MySQL and want to gain a better understanding of locking and transactions as well as how to work with them. While some experience with MySQL is required, no prior knowledge of locks and transactions is needed.

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.
