Hello,

I am using Ver 5.5.27-29.0-log of Percona Server on Linux (x86\_64) (Percona Server (GPL), Release rel29.0, Revision 315)

and I am curious about the --ignore-db-dir Parameter, which is available in “stock” mysql, but seems not to be available in my Percona installation. Am I missing something, or is it maybe planned to be implemented?

Best regards,  
Tobias

Hi Tobias,

–ignore-db-dir parameter is added from MySQL 5.6.3, so it can’t be available in MySQL 5.5 versions even in native mysql and Percona servers.

[http://dev.mysql.com/doc/refman/5.6/en/server-options.html#o](http://dev.mysql.com/doc/refman/5.6/en/server-options.html#o) ption\_mysqld\_ignore-db-dir

For that you have to install MySQL 5.6 which is still in alpha release and not recommended for production servers.
