Did I understand the above correctly? You want a single console address, say 1234, to be able to support multiple clients? I don't know of any z/OS console solution (2074, Visara) that will do that. Do you want the same ability for VTAM terminals? I.e. two different people on the same LU? What about security? Our TCP/IP consoles require a LOGON. I don't want user A and B to "share" a console session. > > Where we had expected it to come up, and stay up from IPL to IPL, we > were very disappointed.

I think this "dropping" at IPL is a "bad thing"(tm) also. Of course, the way that I do things, which is not necessarily correct, is to set the TN3270 client software to automatically reconnect when it drops. > > We did have IBM's direct support and help in getting the > consoles up and > working, and working through the problems we had.
