This tab allows you to set various options for the InnoDB storage engine. For more information about the InnoDB storage engine, see the InnoDB Tables section.
Deactivate InnoDB
Deactivate InnoDB: If enabled, the InnoDB storage engine will be disabled. [SH] This sentence sounds weird; but I also think this option is weird ("activate to deactivate"). Also, it's redundant (see link). This will reduce memory usage if you do not want to use InnoDB tables. You can accomplish the same effect by deactivating the Support for InnoDB checkbox in the Configure Service tab of the Service Control section.
Be careful when enabling that option! If there are databases on the MySQL server that contain InnoDB tables, then those tables will be unaccessible after enabling that option.
Memory
Buffer Pool Size: Sets the value of the innodb_buffer_pool_size variable. Setting this value high reduces the need for disk access, which makes data access in tables faster. Setting it too high may, however, cause paging (which means disk accesses) in the operating system. See the InnoDB Startup Options section for details.
Add. mem Pool Size: [SH] Mike: Add. Mem. Pool Size? This is the memory allocated by InnoDB to store internal data, like data dictionary information. A sensible value of this option depends on the number of InnoDB tables you are using. See the InnoDB Startup Options section for details.
Use AWE Memory: [SH] Mike: memory => Memory If enabled, InnoDB stores the buffer pool in the AWE (Address Windowing Extension) memory. AWE memory is available in Windows operating systems only. The prerequisites of using this option are that the machine where the MySQL server runs on has more than 4 GB of memory, and that the Windows version it runs on supports AWE memory. [SH] Mike: Will the "AWE" options appear in the Gnome/Mac OS versions? [SH] I found no explanation what the usage of AWE memory is good for. It's probably faster, but I can only guess so far. Also, the manual says that 500M is a good value, but doesn't say why. I asked Heikki. For more information about AWE memory, see the InnoDB Startup Options section.
