Method Detail

shouldExceptionTriggerFailover

public boolean shouldExceptionTriggerFailover(java.lang.Throwable ex)

Description copied from interface: LoadBalanceExceptionChecker

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.

Specified by:

shouldExceptionTriggerFailover in interface LoadBalanceExceptionChecker

Overrides:

shouldExceptionTriggerFailover in class StandardLoadBalanceExceptionChecker

Parameters:

ex - exception

Returns:

true if the exception should trigger failover.
