• 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/4.1/en/replication-howto.html
    https://wikis.oracle.com/display/CommSuite/MySQL+High+Availability+and+Replication+Information+For+Calendar+Server
    

Limitations/Things DBHA is not supported

• Currently Monitoring of Slave by admin is not possible
• Monitoring events are not integrated with MS

Appendix

• We can achieve multiple nodes set up(2 master max and remaining would be slaves) with chain way of replication configuration
