Overview of this book

<p>InnoDB, the default storage engine for MySQL, is one of the most robust and commonly used in the world today. It can, however, be initially daunting to learn how to start implementing its features, and it can pose unique problems to the beginner user. This guide is written to address these problems.</p> <p>"Instant InnoDB" addresses everything you need to know for the installation, configuration, load testing, analysis, and long term support of an InnoDB based database environment. If you've ever wanted to learn more about InnoDB but didn't want to sit down with a formidably large or dry read, then the Instant InnoDB&nbsp; is your ideal companion.</p> <p>"Instant InnoDB" guides you expertly through the initial setup and system requirements for getting up and running with a simple environment that can be used for the development and testing of the InnoDB engine.<br /><br />After an in-depth look at basic and advanced configuration settings we delve into the internals of InnoDB that allow it to handle Multi-Version Concurrency Control and ACID transaction compliance. We will then dig deeper into advanced topics, such as memory buffer tuning methods and transaction log file handling. We'll then cover typical approaches and solutions to monitoring the database and reporting on operational states.</p> <p>By the end of the Instant InnoDB , we will have covered the common approaches to troubleshooting and error handling, as well as providing you with solutions to the most common architectural, administrative, and engineering related situations that arise when working with the InnoDB database engine.</p>

Chapter 2. Basic Configuration Parameters

When reading the MySQL documentation you may find that InnoDB has over fifty-eight configuration settings, more or less depending on the version, for tuning the performance and operational defaults. The majority of these default settings can be left alone for development and production server environments. However, there are several core settings that can affect great change, in either positive or negative directions depending on the application workload and hardware resource limits, with which every MySQL database administrator should be familiar and proficient.

Keep in mind when setting values that some variables are considered dynamic while others are static; dynamic variables can be changed during runtime and do not require a process restart while static variables can only be changed prior to process start, so any changes made to static variables during runtime will only take effect upon the next restart of the database server process.
