Re: Multiple master hosts in JDBC connection string

Hi Serhiy,

You probably want to add failOverReadOnly=false and autoReconnect=true properties to your configuration - this should cause Connector/Java to use the second (failover) host to perform writes when the primary is unavailable. Please note that the failover event itself is not seamless - in-flight transactions and connections will throw a SQLException next time they are used, and for good reason:

That said, once the failover event has been dealt with by the application, the connections will be pointing at the failover (second) host, and allowing write operations.

Hope that helps!
