The only required parameter to use InnoDB is @code{innodb_data_file_path},

but you should set others if you want to get a better performance.

The default value for @code{innodb_data_home_dir} is the @code<datadir}

of MySQL. If you do not specify @code{innodb_data_home_dir}, then

you cannot use absolute paths in @code{innodb_data_file_path}.

Suppose you have a Windows NT machine with 128 MB RAM and a single 10 GB

hard disk. Below is an example of possible configuration parameters in

@file{my.cnf} for InnoDB:

set-variable = innodb_lock_wait_timeout=50

Note that data files must be < 4G, and < 2G on

Note that data files must be < 2G in

some file systems! The total size of data files has

to be >= 10 MB.

to be >= 10 MB. The combined size of log files MUST be < 4G

in 32-bit computers.

InnoDB does not create directories:

you have to create them yourself.

Check that the MySQL server

on the same physical disk. Putting log files on a different disk from

data is very often beneficial for performance.

The combined size of the log files MUST be < 4G in a 32-bit computer,

and to make recovery reasonably fast you should keep the combined size

smaller than the buffer pool size.

The meanings of the configuration parameters are the following:
