<p class=MsoNormal style='margin-bottom:12.0pt'>That will not work. Try DNS
SRV. Take a look at this link <a

<p class=MsoNormal>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" target="_blank">192.168.1.5</a><br>
mysql
A <a
href="http://192.168.1.6" target="_blank">192.168.1.6</a><br>
<br>
where <a href="http://192.168.1.5" target="_blank">192.168.1.5</a> & <a
href="http://192.168.1.6" target="_blank">192.168.1.6</a> are mysql cluster
nodes.<br>
<br>
So <a href="http://mysql.somedomain.com" target="_blank">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>

<p class=MsoNormal>This problem has been solved many times. The absolute
most bomb-proof<br>
MySQL failover solution involves a combination of DRBD and Linux HA<br>
(Heart Beat). The replication model has too many issues IMO.<o:p></o:p></p>
