"The user.vtamlib is empty and USSN module is in ADCD.ZOSV14S.VTAMLIB. My plan is to place my own module in JOHNNY.VTAMLIB which resides on a different volume and then add my own lib to the top of VTAMLIB concatenation...... ,,,,,However,after re-IPL,the new logon sreen only works when you connect to it using port 3270.On the other side,if you use TCPIP port 23, the logon screen is still the old one.Why does this happen?" My own system is down at present so I cannot say why the problem being experienced is happening, but having undertaken a similar change then I may be able to offer a solution. The library USER.VTAMLIB has been provide as a repository for this precise situation. (The are other USER. libraries in the ADCD collection to allow other modification, i.e. own TSO Exits, own CLISTs/REXX etc, where own means installation not personal.) The only difference in approach between our two methods is that I created a USER.ZOSV1R3.VTAMLST, and subsequently a USER.Z16.VTAMLST to hold the source code and provide consistent naming. Assembling and linking the USSN into USER.VTAMLIB means that the modified USSN appears for both VTAM and TCPIP access, i.e. whether the Telnet Listener or TCP/IP Port 23 is used. As an asside If there are going to be a number of users accessing the system, use TCPIP as the primary entry. If you drop into VTAM via the Telnet Listener which connects as a local VTAM terminal it generates activity at the Linux level and this can induce poor performance if Linux and z/OS compete on paging activity.
