Good day guys (and girls if any)
I am constantly in a position where variables on a production mysql database needs to be changed. The database runs a 24/7 system and thus to reboot is not preffered and should be the absolute last resort. How can I set variables to be effective immediately? ( I am still a junior in mysql dba and still learning) If I set these will it still be effective should the database be restarted somewhere in the future? Thanks in advance for your help. Regards
