Hi,<br><br>is it fine if I use DSN resolver?<br>Let me explain in detail:<br>I setup a DSN resolver & add A record for mysql servers.<br>mysql A <a href="http://192.168.1.5">192.168.1.5</a><br>mysql A <a href="http://192.168.1.6">192.168.1.6</a><br>
<br>where <a href="http://192.168.1.5">192.168.1.5</a> & <a href="http://192.168.1.6">192.168.1.6</a> are mysql cluster nodes.<br><br>So <a href="http://mysql.somedomain.com">mysql.somedomain.com</a> will point to both servers.<br>
It will do load balance & failover both.<br><br>Please confirm that it will not create any issue.<br><br>Thanks,<br>Krunal Patel<br><br><div class="gmail_quote">On Tue, Nov 25, 2008 at 1:35 AM, Geoffrey Mina <span dir="ltr"><<a href="mailto:geoffreymina@gmail.com">geoffreymina@gmail.com</a>></span> wrote:<br>

MySQL failover solution involves a combination of DRBD and Linux HA<br>
(Heart Beat). The replication model has too many issues IMO.<br>
