Creating a TCP/IP service

Because the client connects to your web services over an HTTP transport you must define a TCP/IP service to receive the inbound HTTP traffic.

Procedure

Use the CICS Explorer® to create a TCPIPSERVICE definition to handle inbound HTTP requests.
  1. Create a TCPIPSERVICE definition by selecting Definitions > TCP/IP Service Definitions. Right-click in the TCP/IP Service Definitions view and select New to create a new definition. Type DFH$EXWS in the Resource Group text box, and type EXMPPORT in the Name text box. You must specify a port number; type in the number of any unused port in your CICS® system. Click Finish to create the TCPIPSERVICE definition.
  2. Double-click the TCPIPSERVICE definition. In the Attributes tab in the TCP/IP Service Definition (EXMPPORT) editor, set the following attributes:
    • Urm must be DFHWBAAX
    • Protocol must be HTTP
    • Transaction must be CWXN
  3. Use the default values for all other attributes.

Optional: Those users that do not use CICS Explorer can use the CEDA transaction to amend and install the resources contained in groups DFH$EXBS and DFH$EXWS.
