ACF/SNA LOGMODE table entries for IMS

IMS allows the user to specify some BIND parameters in a z/OS® Communications Server logmode table entry. The CICS® logmode table entry must match that of the IMS system.

IMS uses, in order of priority, the mode table entry specified in the following places:
  1. The MODETBL parameter of the TERMINAL macro
  2. The mode table entry specified in CINIT
  3. The DLOGMODE parameter in the VTAMLST APPL statement or the MODE parameter in the IMS /OPNDST command
  4. The ACF/SNA defaults.
Figure 1 shows an IMS logmode table entry:
