I was trying to create a dump file from my MySQL database, but when I try it always gives me this error
Operation failed with exitcode 2
The reason for this is that MySQL 5.6 has removed support for "SET OPTION" and your mysql client tools are probably on older version. Most likely 5.5 or 5.1. There is more info about this issue on MySQL bugs website.
The quickest solution is to update your mysql client tools to 5.6 and your problem will be solved. If you are on Linux platform, here is a solution that worked great for me: http://www.markomedia.com.au/mysqldump-mysql-5-6-problem-solved/
