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

Customizing File Manager CICS® Component
- Preparing to access CICS resources from File Manager
- Customizing the operating environment for FM/CICS
  - CICS® resource definitions for FM/CICS
  - Updating the CICS® startup procedures
  - Customizing for CICS® TCP/IP
    - IPv6 support
      The FM/CICS transaction communicates with either the ADFzCC server, or a batch job via TCP/IP sockets and supports both IPv4 and IPv6 networks.
  - Providing OMVS segments for FM/CICS users
    The CICS® region and each individual FM/CICS user must have a user ID defined to z/OS® with an OMVS segment. This allows usage of TCP/IP by FM/CICS.

  You can customize FM/CICS for national languages other than English.
- Verifying the customization of FM/CICS
  After you have completed the initial installation and customization of FM/CICS, you can perform the following steps to verify your customization. You might need to refer to the File Manager for z/OS User’s Guide and Reference for CICS.

IPv6 support

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

If TCP/IP on the system where the CICS® 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 FM/CICS is able to obtain the correct host name of the system.
You can test your TCP/IP configuration by running the FMNCHKH REXX exec member in FMN.SFMNSAM1.
TCP/IP and the resolver on the system where the File Manager 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 File Manager batch job run on the same system.

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