When i connect from client to server the client looks up for the host address and port number in tnsnames.ora and connect to it via listener.ora in server.Where does pga and sga come into picture here?

Also what is the role of sqlnet.ora in client?What will happen if i specify a different port for the instance in tnsnames.ora and listener.ora?
