This event is triggered when an HA event occurs.
// C# public static event OracleHAEventHandler HAEvent;
The event handler receives an
OracleHAEventArgs object which exposes the following properties containing information about the event.

Indicates the database name affected by this event.
Indicates the database domain name affected by this event.

HAEvent is static, which means that any HA Events that happen within the application domain can trigger this event. Note that in order to receive HA event notifications,
OracleConnection objects that establish connections within the application domain must have
"ha events=true" in the application. Otherwise, the application never receives any HA Events.
