Signon security

Depending on whether RNR is activated or not and the types of terminals you are using, signons or logons of VTAM® sessions may be required following IMS restarts.

If RNR is not activated, then both logon and signon of sessions are required. If RNR is activated, then the following types of terminals require signon after a session reconnect:
  • SLU0 (non–printer, 3270, non-SNA)
  • SLU1 (non-printer only)
  • SLU2
  • NTO
If RNR is activated, then the following types of terminals sign on automatically after a session reconnect:
  • SLU0 (Finance/3600)
  • SLU0 (SLUP)
  • SLU1 (3284, 3286, non-SNA)
  • ISC (LU 6.1)
