Hi there ! Could somebody guide me a bit on how to load balance Mysql servers ? Actually we can do read-only querys but on other operations the Mysql client we use says that "can't lock file". I think the balancer send that stream to one Mysql server but then when It goes back it doesn't know what is the correct place to send it. Thanks. We are doing it with a CSS, and we have two Mysql servers to process the queries.
