Signing on and queue LTERM allocation

Signing on to an ETO terminal identifies a user to IMS, creates a user structure, and connects this user structure to the terminal structure.

Users at VTAM® terminals can sign on by:
  • Issuing the /SIGN command.
  • Signing on at the DFS3649 message screen.
  • Providing user data with the session initiation request.

Users that establish a dynamic VTAM session with IMS must enter valid signon data before LTERMs are allocated to the session. You can require that the signon data be validated by a security product, such as RACF®.
