We will rely on Mysql's Connector properties to achieve Master-Master DB HA
- Look at the following link to know the parameters used to achieve HA using mysql connector
  http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html
We need to have at least 2 nodes which are connected through 2-way replication and should be consecutive in connector's url
- look at the following urlss to setup Mysql replication
  http://dev.mysql.com/doc/refman/5.0/en/replication-howto.html
  https://wikis.oracle.com/display/CommSuite/MySQL+High+Availability+and+Replication+Information+For+Calendar+Server
The following configuration need to be done in my.cnf of each mysql server to clean up bin log files automatically.
expire_logs_days=10 (Number of days to keep the bin log files)
max_binlog_size=100M (The max size of each bin log file)
To change the bin log files location please use the following property in my.cnf of each mysql server
log-bin=/var/lib/mysql/binlog/bin-log (Remember here “bin-log” is the file prefix)

Currently Monitoring of Slave by admin is not possible
Monitoring events are not integrated with MSClean up of bin log files generated because of replication on database nodes is not done my MS.It is the job of admin to clean those files frequently.
Spli Brain problem will cause the sync issues

Appendix

What if I want to do a Manual Switch over from Master-1 to Master-2?
- Put a 2 way replication as above and do not enable the db ha in db.properties. I.e put the value false against the following property in db.properties
  db.ha.enabled=false
