Implement the TCP/IP Sockets Interface Parameters

Use this procedure to enable TCP/IP support.

Access to sockets interfaces requires UNIX System Services authorization provided by an OMVS segment security definition.

To implement the TCP/IP sockets interface parameters

1. Enter U next to the TCP/IP Sockets Interface parameter group.

   The first SOCKETS - TCP/IP Sockets Interface panel appears.

2. Tab to the TCP/IP Software Type input field, and enter the required value.

   Only one type of TCP/IP software can be configured as the sockets interface in each region.

3. Complete the remaining fields on the first panel.

   Note: For more information, press F1 (Help).

   The Inbound Connections Port field contains a default port number. If another region on this system is already using that number, tab to the field and change it.

   Important! The port number must be unique on a system.

4. Press F8.

   The second panel for this parameter group appears.

5. Complete the fields on the panel.

   Specify the details of the TCP/IP software as follows:

   • If you are using the IBM Communications Server, enter your TCPIP.DATA data set name in the TCPIP.DATA DSN field and review the Domain Name Resolution fields.
   • If you are using CA TCPaccess CS, tab to the CA TCPaccess CS SSID field and enter the required SSID. If you are unsure of the CA TCPaccess CS subsystem ID, access the CA TCPaccess CS startup procedure and check the value of the SSN parameter.
6. Press F6 (Action) to set the specified values and start the interface.
7. Press F3 (File) to save your settings.

   The Customizer : Complete Setup panel appears with the TCP/IP Sockets Interface Reviewed field marked as YES.

8. Press F3 (Exit).

   The Customizer : System Parameters panel appears.

If you enabled TCP/IP support using CA TCPaccess CS, see the following section.
