Good suggestion, though I can't test it
Ah, I didn't think of that. Unfortunately, I can't test it out now. I'm under a really right schedule and since I was stuck using heartbeat and ldirectord for load balancing, I decided to try a different solution. Since I'm using glassfish and my app is pure Java, HA-JDBC was easy to plugin and it handles the load-balancing and health checking quite well so far. If I end up going back to heartbeat and ldirectord, I'll definitely try mysqld. Thanks.
