We run a server with MySQL 5.5. 95% of the tables are set to the InnoDB engine.

However whenever I look at the my.ini file (using the MySQL Workbench) under mysqld section innodb is unchecked and OFF is selected in the drop down. I don't see this line added to the my.ini file when viewing with notepad.

Should I check this setting and set it to ON so we can utilize the enabled innodb settings (buffers & log file etc.) or does this not matter?


  • Currently if you download mysql 5.5.19 RPM's (source included) for linux generic INNODB is not available. Inspecting source RPM file WITH_INNOBASE_STORAGE_ENGINE is not on. [SOLVED] No InnoDb was caused my invalid innodb files due to changing innodb related files settings (on my.cnf) with the server running. Jan 3 '12 at 11:27

Sounds like an issue with MySQL Workbench.

MySQL 5.5 has a default storage engine of InnoDB.

In fact, the option default_storage_engine is predefined as follows:

  • MySQL 5.5.4 and prior, MyISAM
  • MySQL 5.5.8 and after, InnoDB

There is another option called storage-engine, which was deprecated as for MySQL 5.5.3. Keep in mind that MySQL 5.5.8 was the very first GA release.

I would strongly suspect MySQL Workbench if it is coded to check storage-engine instead of default-storage-engine. This would allow MySQL Workbench to monitor older release of MySQL.
