TCP/IP Customization

Welcome to the IBM TCP/IP Configuration Demo for z/OS. In preparation for customizing TCP/IP, IBM recommends you complete the input worksheet.

Getting Started

TCP/IP customization panels are divided into five categories:

  1. Basic Settings - where you configure:

  2. Network Connections - where you configure:

  3. Telnet 3270 server - where you configure the Telnet 3270 server.

  4. FTP servers - where you configure one or more FTP servers.

  5. FTP clients - where you configure one or more FTP clients.

Navigate through the panels for each of these main categories to enter your configuration data. Once you have completed your customization tasks, select Save from the main TCP/IP customization panel to save the data onto the workstation. You can also select the CANCEL button, which will discard any data you have entered.

To begin, select a category and click the Customize button (or double click on the category). Panels will be displayed specific to that category. Throughout the customization phase, use the OK, Close or Finish buttons to indicate that you have completed configuration data for a panel or set of panels, or use the CANCEL button to discard data.

Push buttons
Click Customize or double click one of the tasks to enter the customization panels.
Click Report to show the current TCP/IP configuration files for TCPIP.DATA, PROFILE.TCPIP, and OMPROUTE. This includes the TN3270 configuration.


Click Save to close the TCP/IP console and save the data onto the workstation.
Click Cancel to close the TCP/IP console and discard any changes to the configuration data.

Scope of the TCP/IP configuration

Information is collected allowing for the creation of a simple TCP/IP configurations with simple instances of OMPROUTE, and all device types including static VIPA. To define more complex configurations see "z/OS IBM Communications Server: IP Configuration Guide". Information collected for TN3270 server, FTP servers, and FTP clients is extensive and provides all the options most customers would need.

The panels ask for information that is converted into TCP/IP configuration files, configuration statements and parameters. However, if you are familiar with TCP/IP configuration, you will notice that the configuration demo does not ask for a value for a specific TCP/IP parameter that you are expecting it to. A single query of a data field on a panel may result in multiple TCP/IP configuration statements. For example, you may add a Channel-to-Channel (CTC) device. On the customization panel, information such as the Device name, Device number, Link name, and IP address of the link will be collected. This information will be used to create the DEVICE, LINK, HOME, and the static or dynamic route configuration statements. Whenever possible, existing defaults for configuration parameters are used. The information collected allows for the creation of the following files and configuration statements:

  1. tcp.data

  2. profile.tcp

  3. OMPROUTE

  4. TN3270

  5. FTP Servers

  6. FTP Clients

For TCP/IP to function correctly, corresponding VTAM definitions may be required, which are beyond the scope of the IBM TCP/IP Configuration Demo for z/OS configuration.

The output

The configuration demo marks each TCP/IP configuration as either 'Not customized', 'Customized', or 'Incomplete'. Initially a configuration will be 'Not customized' until you select the Save button on the main TCP/IP customization panel. At that time, your data is analyzed for completeness. If it is complete, the data is saved on your workstation. If it incomplete, specific messages will describe why it is incomplete and how to complete it. You may save incomplete configurations, which will be marked as 'Incomplete'.

To view the configuration files, select the Report button on the main TCP/IP customization panel. All of the configured profiles will be displayed and you can save them to your workstation by selecting the Save button. The FTP configuration files for server and client can be seen by selecting the FTP task and selecting the Customize button. Then from the main FTP table, select the Report button to view the configuration files. The configuration file member names will be TCPDATA, PROFILE, PORTS, TN3270 and OMPROUTE, which represent the TCP/IP configuration files typically known as TCP.DATA, PROFILE.TCP and OMPROUTE. The PORTS and TN3270 files are INCLUDEd from the PROFILE file. Additionally, for each FTP server you define a new configuration file and start procedure will be created as members. You choose the member names when defining the FTP servers. Likewise, for each FTP client you define a new configuration file will be created as member in the data set.

Installation

Once the configuration files are saved, please read the installation instructions for various options on how to proceed.
