>Where can i find some information about ClientNodeName parameter?

The Subject and body ask about two different things.
Here are my notes about them...

ClientNodeName                          Windows Registry value, planted as part
                                        of setting up TSM Client Service
                                        (scheduler), storing the name of the
                                        computer. Corresponds to the TSM API
                                        value clientNodeNameP (q.v.).
clientNodeNameP                         TSM API: A pointer to the nodename for
                                        the TSM session. All sessions must have
                                        a node name associated with them, and
                                        this sets it for API interactions.
                                        The node name is not case sensitive.
                                        This parameter must be NULL if the
                                        passwordaccess option in the dsm.sys
                                        file is set to generate. The API then
                                        uses the system host name.
                                        (Documented in the TSM client API
                                        manual)
