In this step you will create a host connection file that
allows you to connect to your target z/OS® host.
The z/OS host must have CICS® Transaction Server for z/OS V3.1 or later installed and
the catalog sample application (egui) must be available on CICS (see Required environment, materials, and assistance).
Create a host connection file
To create
a host connection file for your z/OS host:
In the EST Project Explorer, right-click the CatalogSample.Terminal subproject.
Click . The New Host Connection wizard
opens.
On the first page of the New Host Connection wizard, titled Specify
Destination:
In the File name input field, type the
name that you want to use for the host connection file (for example, system).
Click Next.
On the second page of the New Host Connection wizard, titled Basic
Settings:
In the Host name input field, type the
IP address or the host name of your z/OS host
(for example, system.company.com).
In the Port input field, type the number
of the host port that you want to attach to (for example, 623).
Do not change the contents of the remaining input fields.
Click Finish. The wizard creates the
new host connection file and opens it in the host editor.
Note: - When a host connection file is opened in the host editor, the
host editor automatically attempts to connect to the host using the
values specified in the host connection file.
- The connection should be successful.
- If the connection fails, then you can attempt to connect to the
host system by following these steps:
- If the session is not connected:
- Click the Properties tab at the bottom
of the host editor window.
- The Host Connection Settings window opens
in the editor area. In the Properties window, verify that the host
connection is configured properly.
- If you make any changes, press Ctrl-S to save your changes.
- Click the Terminal tab at the bottom of
the host editor window. The session window opens in the editor area.
- On the toolbar at the top of the session window, click the Connect
to Host
icon.
- If the session is still not connected:
- Verify that the line is active and that the host is configured
properly.
- Click the Connect to Host
icon
again.
For now, close the host editor.
Note: The new host connection
file should be displayed in the Hosts subfolder.
To open this subfolder, in the EST Project Explorer, expand .
