ETO and 3600/Finance and SLU P

You can change the signon identification by using another IMS /SIGN command at any time. LTERMs are assigned to the terminal during system definition and are not affected by the signon process or by the SNA STSN message recovery process. The signon simply provides user access and input authorization.

IMS supports 3600/Finance and SLU-P terminals as dynamic terminals. They can use autologon or signon data with the logon request in order to dynamically allocate user structures. Signon data must be provided at session initiation for ETO 3600/Finance and SLU-P terminals. Signon data can be supplied in the Logon exit routine (DFSLGNX0) at the cold start of a session. The LTERMs and user IDs allocated at the cold start session are retained across sessions and IMS outages because of the VTAM® STSN message resynchronization requirements. This requires that the same user signon data be used for subsequent warm-start sessions to both reverify the user and to allow message resynchronization.

When dynamic XRF Finance and SLU-P terminals are defined as XRF class–2, automatic re-signon and logon occur at takeover time.
