To use VTAM® terminals with CICS®, ensure that your CICS regions are defined to VTAM before you
attempt to run them.
To define your CICS regions to VTAM (as VTAM application programs):
- Define VTAM application program minor nodes for your CICS regions, by specifying APPL definition
statements in a member of the SYS1.VTAMLST library (or your own user.VTAMLST
library). See Defining specific CICS APPL statements to VTAM.
- Issue a VARY ACT command to activate the APPL definitions, and enable
the CICS regions to connect to VTAM.
- Ensure that you have properly defined your VTAM terminals for connection to CICS. This is particularly
important if you intend using the CICS autoinstall function. For those terminals
for which you want to use autoinstall, code LOGON mode table entries that
match the model TYPETERM/TERMINAL definitions that CICS uses. You can either code your own autoinstall
models, or use the CICS-supplied model definitions that are generated for
you when you initialize the CICS system definition data set (CSD).
For information about defining model and terminal resource definitions to CICS, see the CICS Resource Definition Guide.
For programming
information about matching VTAM LOGMODE definitions with CICS model definitions,
see the CICS Customization Guide.
For further information about defining VTAM resources, see the z/OS V1R4.0 Communications Server: SNA Resource Definition Reference and z/OS Communications Server: SNA Network Implementation manuals.
