See Documentation for migration from MyISAM to InnoDB for the current discussion which prompted the creation of this page. --Frank Ralf 11:41, 24 November 2010 (UTC)
MySQL Configuration
Before attempting to change the table type, you should:
- check InnoDB is enabled. Log in to MySQL and run the command SHOW ENGINES. Make sure that support for InnoDB shows either "YES" or "DEFAULT".
- set innodb_file_per_table if required. This setting can be useful for large installations, but it only affects newly created tables and can't be applied retrospectively.
Various Methods described in Moodle Forums
- use the CLI script in admin/cli/mysql_engine.php (requires access to shell, mysql only, and the config.php must only have one moodle instance)
- use PHPMyAdmin entering Structure view of a table and clicking Operations tab. Look for Storage Engine parameter. This is a tedious task due to the number of tables [1]
