Define the Communications Control Unit to z/OS
If you have not already done so, define the communications control
unit for the z/OS host, such as the 3172 or the 3745 control unit, to
z/OS. Use either an z/OS configuration program (MVSCP) or a
hardware configuration definition (HCD), depending on the version
of your z/OS system:
• When using a version earlier than z/OS 4.1.0, use an MVSCP.
• When using a version of z/OS 4.1.0 or later, use an HCD or an
MVSCP.
For more information about using these methods, refer to:
• MVS/ESA* Migration Planning: Dynamic I/O Configuration
• MVS/ESA Hardware Configuration: Using the Dialog
Modify the TCP/IP Profile in z/OS
The TCP/IP profile contains system configuration statements used
to initialize the TCP/IP address space. Of those statements, the
following are subject to special considerations when you are
printing from PSF on TCP/IP-attached printers. Samples of these
statements are printed in bold in the example shown in Figure 35.
