Before you shut down the InnoDB storage engine and start the basic built-in InnoDB in MySQL, review the configuration files. Changes to the startup options do not take effect until the server is restarted, or the InnoDB storage engine is uninstalled and reinstalled.

The InnoDB storage engine introduces several configuration parameters that are not recognized by the built-in InnoDB in MySQL, including: innodb_file_format, innodb_file_format_check, and innodb_strict_mode. See Section B.1, “New Parameters” for a complete list of new configuration parameters in the InnoDB storage engine. You can include these parameters in the configuration file, only if you use the loose_ form of the parameter names, so that the built-in InnoDB in MySQL can start.

If the InnoDB storage engine was installed as a dynamic plugin, the startup option ignore_builtin_innodb or skip_innodb must have been set to disable the built-in InnoDB in MySQL. These options must be removed, so that the built-in InnoDB in MySQL is enabled the next time the server is started.

If the InnoDB storage engine was loaded via plugin_load option. This option has to be removed too.

In MySQL, configuration options can be specified in the mysqld command line or the option file (my.cnf or my.ini). See the MySQL manual on Using Option Files for more information.
