Figure 5-22 shows the properties that must be configured for CTC Links.
Complete these fields as follows:
Mainframe IP Address – The IP address of the mainframe this connection is to
communicate with. This must match the HOME IP address assigned in the
TCP/IP Profile.
Link Description – A description of the link being defined.
Channel Adapter – Use your mouse to select the PCI ESCON Adapter this
connection is to be defined on.
ESCON Path – Use your mouse to select a path from those defined for this
ESCON adapter. If no paths are available, you will have to define the ESCON
configuration. Click on Configure ESCON… Refer to Chapter 4.
Read Device – Select the device from the list of available devices on the selected
Path. The device must be the first of two consecutive devices that will be used by
this connection. If no devices are available, click on Configure ESCON…
IOBufferSize – The IO Buffer Size is defined in the Mainframe’s TCP/IP
configuration. The value entered in this field must be between 8192 and 65535
and must match the value defined on the mainframe. In the mainframe TCP/IP
Profile this value is set with either the LARGEENVELOPEPOOLSIZE or
IOBUFFERSIZE parameter depending on the version of TCP/IP in use. The
recommended IOBufferSize for CTC connections is 65535.
