Re: When do client connections disconnect

Tech-Archive recommends: Speed Up your PC by fixing your registry

Here is an article that answers my question (although it is for SQL Virtual
Server) it describes the issue that I am having with my application.

This is the only documentation I was able to locate describing the issue.
Perhaps Microsoft should provide a more general advisory.

See section that describes behaviour of TCP

Again, cluster aware client applications should handle this. The server is a

Hi Rodney: Just because a ping test fails does mean existing socket
connections are cleaned up by the cluster.

It does terminate, a ping test will fail. If your application is cluster
aware the application will handle this delay/error and it will reconnect.

Thanks for your response: But let me ask the question again.

I would like my client applications to start reconnecting as soon as
the
IP
has failed over. The server processes on the failed machine may take a
while
to completly shutdown and clean up socket connections.

So, does the failover of an IP and network name terminate socket
connections. Or, do I have to wait for the old server processes to
complete
their shutdown.

Are there any kind of configuration options to tear down socket
connections
as a result of the IP and netwrok name failover?

If the application is not cluster aware, you will disconnect.

I have set up an application to run in a virtual server.

Can anyone tell me if clients connected to the application will see
a
connection loss as a result of the IP resource going offline OR do
the
server
applications have to terminate the connections/die before the
clients
will
see the lost connection.
