You use a COBOL Application debug configuration to debug projects developed on a remote UNIX machine. Before you can debug
the remote application, you need to have an X window implementation installed and running, so that the output of a remote
application running on a UNIX machine can be viewed on your local machine. You do not need X window for other debug configuration
types.
Windows:
Micro Focus ViewNow X is provided as part of
Visual COBOL. See
Installing X Windows on Windows
in the
Installation section. Find the ViewNow X documentation on the
Micro Focus SupportLine
dropdown menu.
UNIX:
Ensure the local X11 server can receive connections from the remote machine. You can do this using the
xhost + command or by enabling SSH port forwarding. Alternatively, enable TCP/IP connections for X11 by setting a value in a configuration
file in a manner appropriate to your operating system. For example:
- Red Hat: run the
gdmsetup utility and deselect
Deny TCP connections to Xserver in the Security tab (this configures
DisallowTCP=false in /etc/gdm/custom.conf)
- SUSE: set DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="yes" in
/etc/sysconfig/displaymanager
Specify the details about the display that the X11 server tries to contact in the IDE preferences as follows:
- Click
Window > Preferences > Micro Focus > Debug.
- Type the display details in the
Default X Server (DISPLAY) field.
The default
Default X Server (DISPLAY) value is
clientMachineName:0.0.
- Optionally, in the
Default cobdebugremote port field, you can modify the default (8000) port number.
- Optionally, modify any of the remaining settings.
- Click
Apply and Close.
