-----------------------------------------------------------

In the standalone case, simple broker, not master slave. disable the lock thread for the jdbc
persistence adapter. set  useDatabaseLock=false. This is what is initiating the shutdown of
the broker when the connection to the DB dies, at it assumes that another broker is ready
to take its place. It is not needed in the standalone case.
Otherwise,look into a connection pool that will do retries for you.

> When I database is idle for too long or I manually restart database, broker is shutting
down. Does it not automatically try to reconnect? Am I missing anything?
> I am setting validationQuery and testOnBorrow to true in broker-config.xml datasource
bean.
> Do I need to do anything else to tell broker for keep trying for database connection?
