Put the ACS java app in the same server and it will always get working mysql server when it is working. Also I suggest you start using pacemaker, corosync or cman.
My management server is actually a virtual instance on RHEL active/active drbd cluster (so live migration works). If you want to test how it behaves, stop mysql and check for yourself. I highly doubt anyone has tested it yet. Regards, F.
