I'd like to know if sessions lost during an MSCS node move is a normal behaviour with Microsoft Windows 2000 AS, SAP R/3 4.7 (CI instance) or there's something wrong with our configuration.
We just completed the SAP installation on Cluster. Loosing sessions when you move the group is normal behavior. SAP resource will be restarted on the surviving node. Hence the user will loose the connection.
For client-side applications that have "state-full" connections to the server, a new logon is typically required following a server failure. In many cases, this approach is required for security purposes. For example, this is how SAP R/3 works--if the server connection is lost, the user is prompted to log on again to make sure it's the same user accessing the application.
