Agent useful in a VIPless environment to redirect application server to the database master with IPtables. Basically, the application servers are part of the PRM master-slave clone set and forbidden to be master. Instead of the mysql_prm script, they run the fake_mysql_novip script (rename mysql_prm) locally. They'll get the notification and readapt an IPtables rule to direct traffic to the master.
A slightly modified version of the IPaddr2 script that better behaves with ClusterIP. See: http://www.mysqlperformanceblog.com/2014/01/10/using-clusterip-load-balancer-pxc-prm-mha/.
