To debug locally-developed programs on a remote machine you must start cobdebugremote (Windows) or cobdebugremote32 (UNIX) (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:
If you have developed a COBOL remote project on a machine using a local Eclipse installation and a remote UNIX machine running Micro Focus Visual COBOL Development Hub, use debug configurations in the same way as locally-developed projects. However you do not need to start the cobdebugremote (Windows) or cobdebugremote32 (UNIX) process (or cobdebugremote64 for a 64-bit process) or identify a port for it to listen on, merely select the remote project in the debug configuration.
To debug a COBOL project, the project must be compiled for debugging and you need to create a debug configuration.
For more information, see the section on Remote Debugging in your product help.
