I created a new mysql database and i want to use foreign keys with it… I googled and found out this…

InnoDB is one of MySQL storage engines, it supports transactions, row-level locking, and foreign-keys. However, by default, InnoDB is not enabled by XAMPP. To enable it, locate the my.cnf configuration file (normally in C:/xampp/mysql/bin directory) and search for the following lines:

# Comment the following if you are using InnoDB tables

But the path C:/xampp/mysql/bin directory in my system doesn’t seem to have such a file…

Look at this image http://img691.imageshack.us/img691/524/mysqln.jpg

Where is my.cnf file?

Any suggestion…

    Comment the following if you are using InnoDB tables

    skip-innodb
innodb_data_home_dir = "C:/xampp/mysql/"
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = "C:/xampp/mysql/"
innodb_log_arch_dir = "C:/xampp/mysql/"

    You can set .._buffer_pool_size up to 50 – 80 %

    of RAM but beware of setting memory usage too high

    innodb_buffer_pool_size = 16M
innodb_additional_mem_pool_size = 2M

    Set .._log_file_size to 25 % of buffer pool size

    innodb_log_file_size = 5M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
