HAEvent

This event is triggered when an HA event occurs.

Event Data

The event handler receives an OracleHAEventArgs object which exposes the following properties containing information about the event.

Remarks

The 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.
