To debug locally-developed programs on a remote machine you must start cobdebugremote32 (or cobdebugremote64 when debugging 64-bit processes) before communication can be established. See the Visual COBOL help for more information on cobdebugremote.
To debug remotely-developed programs on a remote machine:
You use a local Visual COBOL installation to develop remote projects on a remote UNIX machine that has Micro Focus Visual COBOL Development Hub installed.
To debug a COBOL project, it must be compiled for debugging, and you need to create a debug configuration.
For more information, see the section on Remote Debugging in your Visual COBOL product help.
