Planning for ETO

Migrating a static-terminal environment to an ETO environment requires planning.

Although you can continue to define VTAM® terminals and LTERMs to IMS during system definition, if you do so:
  • You cannot take advantage of the ETO features that exist for those terminals.
  • You must fully define the terminal. You must supply all TERMINAL macros, NAME macros, and parameters, or use type-2 CREATE commands to supply the information.

ETO terminals must be VTAM terminals.

Restrictions: The following VTAM terminals cannot be ETO terminals:
  • IMS master terminal (MTO)
  • IMS secondary master terminal
  • MSC physical and logical links
  • ISC sessions that are used by XRF for surveillance
  • LU 6.2 terminals (dynamically created and managed by APPC/IMS)
