FailoverEvent Enumeration

FailoverEvent.Begin

Indicates that failover has detected a lost connection and that failover is starting.

FailoverEvent.End

Indicates successful completion of failover.

FailoverEvent.Abort

Indicates that failover was unsuccessful, and there is no option of retrying.

FailoverEvent.Error

Indicates that failover was unsuccessful, and it gives the application the opportunity to handle the error and retry failover. The application can retry failover by returning FailoverReturnCode.Retry for the event notification.

FailoverEvent.Reauth

Indicates that a user handle has been reauthenticated. This applies to the situation where a client has multiple user sessions on a single server connection. During the initial failover, only the active user session is failed over. Other sessions are failed over when the application tries to use them. This is the value passed to the callback during these subsequent failovers.
