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>

Troubleshooting system issues


System crashes are never a positive event for a production server but the troubleshooting process doesn't have to be painful if one is aware of the processes ahead of time. InnoDB system failure issues can typically be attributed to hardware limitation or configuration errors where usable limits of buffers or logs were exceeded.

InnoDB system crashes

InnoDB, while typically a very stable database engine for high traffic transactional environments, is not without flaws. Sometimes buffers crash, unknown bugs occur, or other issues arise that can cause a database to suffer downtime. Luckily we can rely on ACID compliance to ensure that no data is lost in the event of a crash. If you have set InnoDB to use ACID compliant settings you will not lose data unless an external issue has occurred. External issues includes InnoDB thinking it has written data to disk but a Software RAID mechanism or RAID system using a non-battery backed cache, has not fully written changes...
