MySQL Performance & Tuning

Prerequisites:

Delegates must have a working knowledge of MySQL Database Administration.

Course Description:

This MySQL Performance & Tuning course is designed for Database Administrators who wish to monitor and tune the performance of MySQL servers and databases. The course provides practical experience in monitoring and tuning MySQL servers and databases.

The delegate will practise:

• Developing a monitoring and tuning plan
• Using monitoring and diagnostic tools
• Using the Information Schema and Show commands to collect data for tuning
• Understanding normalization and de-normalization and their effect on performance
• Using server configuration and status variables
• Understanding the output from the Explain command
• Identifying and improving problem queries
• Making efficient use of indexes
• Monitoring and sizing memory caches
• Monitoring locks
• Tuning the MyISAM storage engine
• Tuning the InnoDB storage engine
• Tuning other standard storage engines
• Comparing and tuning dump and load performance
• Evaluating the use of partitioning for performance

Please note that this MySQL Performance & Tuning course does not cover clustering (other than at overview level), replication or non-standard storage engines such as Falcon and PBXT.
