IPv6 support

The ZDT/CICS transaction communicates with either the ZCC server, or a batch job via TCP/IP sockets and supports both IPv4 and IPv6 networks.

If TCP/IP on the system where the CICSĀ® region is running supports Internet Protocol version 6 (IPv6), the following additional requirements exist:
  • TCP/IP and the resolver on the system where the CICS region is running must be properly configured so ZDT/CICS is able to obtain the correct host name of the system.

    You can test your TCP/IP configuration by running the HFMCHKH REXX exec member in HFM.SHFMSAM1.

  • TCP/IP and the resolver on the system where the Z Data Tools batch job is submitted must then be able to translate the host name that was obtained and passed by the CICS transaction into an appropriate IP address for the system where the CICS region is running.
Note: The requirements listed above apply for IPv6 networks even if the CICS region and Z Data Tools batch job run on the same system.

See z/OS Communications Server: IP Configuration Guide for further details.
