Subsequent start-ups are different from the first start-up.
Starting an application on subsequent occasions:
- Use the registrationStatus API in the SUPApplication class to determine if the application has already
                    been registered. If it has been registered, then only perform the following steps:
- Get the application instance.
 
- Set the applicationIdentifier. The applicationIdentifier must be the same as the one used
                            for initial registration.  
 
- Initialize the generated package database class with
                            this application instance.
 
Note: Once the application is registered, changes to any of
                        the application connection properties do not take effect. To modify the
                        connection properties, unregister the application, change the connection
                        properties and then register again. Unregistering the application also
                        removes the user from the server. 
 
- Set up the connection profile properties if needed for database location and tuning parameters.
 
- Set up the synchronization profile properties if needed for SSL or a relay server.
 
- Start the application connection to the server using the existing connection
                    parameters and registration information.
