Rational Developer for System z, Version 7.6

4B. Define host connection

If you selected the Recording interactions with a terminal application radio button on the third page of the New Service Flow Project wizard, then the fourth page of the wizard is the Define host connection page, which allows you to create a flow containing a sequence of Invoke screen operation nodes, each node managing a screen of a terminal application.

Recording interactions with a terminal application

To create a flow containing a sequence of Invoke screen operation nodes:
  1. On the Define host connection page:
    • Use this page to specify the settings for a host connection file that will allow you to connect to the host on which your terminal application runs.
    • This page is similar to the Specify Destination page and the Basic Settings page of the New Host Connection wizard.
    • For help with the fields of this page see the help for the corresponding fields in the New Host Connection wizard (see Destination settings and Basic settings).
  2. Click Next to go to the next page of the wizard if there is one (see 5. COBOL import settings and 6. PL/I import settings) or click Finish to terminate the wizard and create the new service flow project.
  3. When the wizard terminates:
    1. The wizard creates the new service flow project.
    2. The wizard creates a host connection file in the Hosts subfolder of the terminal applications subproject of the new service flow project.
    3. The wizard opens the host connection file in the host editor and attempts to connect to the host.
    4. If you specified an interface operation on page 2 of the wizard, then the wizard also performs the following steps:
      • It creates an input message file and an output message file containing messages defined according to the patterns that you specified on page 2 of the wizard.
      • It creates an interface operation file that contains:
        • A default port type of programs.
        • The name of the operation that you specified on page 2 of the wizard.
        • References to the new input message file and the new output message file.
      • It creates a variable message file.
  4. At this point, you can record a flow by using the flow recording feature of the host editor (see Recording a flow in the host editor).
