2.13 Send-host specification facility

When TP1/Client requests establishment of a connection to the server, the host that sends the request can be specified. This functionality is called the send-host specification facility.

If multiple network adapters are connected to the host on which the CUP is operating, TCP/IP determines the host that the CUP uses to request establishment of its connections. However, if you use the send-host specification facility, you can specify the host that sends the connection establishment requests.

The sending host is specified for DCCLTCUPSNDHOST of the client environment definition.

The following figure shows the difference when the send-host specification facility is used and when it is not used.
