Falling back from TCP/IP to VTAM for static ISC TCP/IP terminals

Falling back from TCP/IP to VTAM® for a static LU 6.1 ISC terminal requires updates to the DFSDCxxx PROCLIB member and a cold start of IMS.

The default communication protocol for LU 6.1 ISC terminals is VTAM.

To fall back to VTAM:

Procedure

  1. Delete the ISCTCPIP parameter that specifies the node name of the terminal from the DFSDCxxx PROCLIB member.
  2. Cold start IMS.

    If a warm or emergency restart is performed, the ISCTCPIP parameter remains in effect.
