Providing OMVS segments for ZDT/CICS users

The CICSĀ® region and each individual ZDT/CICS user must have a user ID defined to z/OSĀ® with an OMVS segment. This allows usage of TCP/IP by ZDT/CICS.

If an OMVS segment is not defined, message HFMCA021 may be issued with the INITAPI function when a user attempts to run the ZDT/CICS transaction.
