I'm not the only one confused. Any ideas? -------- Original Message -------- Subject: Re: Rotating the BINLogs Date: 9 Feb 2001 12:37:03 -0300 From: "Rodolfo Sikora" <[EMAIL PROTECTED]> To: Leonardo Dias <[EMAIL PROTECTED]> I'm really confused like you. I've been using flush logs on master... I don't know exactly how to use PURGE MASTER LOGS TO, RESET SLAVE and RESET MASTER. If you learn how to use them, please send me an email.
