Description

The OnRecover event fires after AnyDAC discovered that connection to DBMs is losted. The event handler can analyze the reason, ask user how to proceed, show some status and returns the action, AnyDAC should take:

Action	Description
faDefault	If ResourceOptions.AutoReconnect =True, then AnyDAC will try to reconnect, otherwise will raise an exception, that connection is losted. By default ResourceOptions.AutoReconnect = False.
faFail	Close connection and raise an exception, that connection is losted.
faRetry	Try to reconnect.
faCloseAbort	Close connection and abort current operation.
faOfflineAbort	Switch connection to the offline mode and abort current operation.

If event handler is not assigned, then AnyDAC will take default (faDefault) action. If after 3 trials connection cannot be restored, then AnyDAC will close connection and raise an exception, that connection is losted.
