| public void | init(Properties
configuration values as passed to the connection. Note that
in order to support javax.sql.DataSources, configuration properties specific
to an interceptor must be passed via setURL() on the
DataSource. Extension properties are not exposed via
accessor/mutator methods on DataSources. props)Called once per connection that wants to use the extension The properties are the same ones passed in in the URL or arguments to Driver.connect() or DriverManager.getConnection(). |

|---|---|
| public boolean shouldExceptionTriggerFailover(Throwable ex) Invoked to determine whether or a given SQLException should trigger a failover in a load-balanced deployment. The driver will not pass in a Connection instance when calling init(), but it will pass in the Properties, otherwise it acts like a normal Extension. One instance of a handler *per* JDBC connection instance will be created. If you need singleton-like behavior, you're on your own to provide it.
