On a PC desktop (Windows or Linux or >*BSD), you could just fire up multiple TN3270 sessions. ... One of the primary advantages of session managers has nothing to do with multiple sessions. It is protection against session outages. For most, if not all, session managers a network outage breaks the session between terminal and session manager, but not the session(s) between session manager and application. When a user's session is brokens he/she can log back on and be right back on the original sessions. maybe a screen has been lost, but not the session and its historical context. As an extra bonus, the LOSTERM or NSEXTIT code in the session manager is usually much lighter than the equivalent function in a CICS or IMS - no transaction backout, etc. Losing a bunch of sessions with a session manager puts a lot lighter load on the processors than losing the same number of sessions with a transaction processor.
