Appendix E. Establishing the host communication

To communicate with HCD from an HCM client on your workstation, you must set up the host communication depending on your operating system:

• For information regarding z/OS, refer to Setting up TCP/IP definitions for z/OS
• For information regarding z/VM, refer to information unit Setting up TCP/IP definitions for z/VM in z/OS and z/VM HCM User’s Guidez/OS and z/VM HCM User’s Guide.

The host communication is also used when communicating between different HCD systems, for example, for tasks like HMC-wide activation.
