Debugging using a live recording

Restriction: Reverse Debug and Live Recording functionality is licensed and installed separately from undo.io. You can enable reverse debug functionality by downloading the extension from the Micro Focus Marketplace.

This functionality is only supported on the following platforms:

Red Hat Linux (x86 and x64)
SUSE Linux Enterprise Server (SLES) 12 SP2 (x64 only)
CentOS 8.2 (x64 only)
Ubuntu Linux 20.04.x (LTS) (x64 only)

Additional restrictions apply. For details, see the Reverse Debug and Live Recording topic in the Known Issues and Restrictions section of this documentation.

Windows Platforms: To use this option, you must connect to Visual COBOL Development Hub running on one of the supported UNIX platforms listed above.

You can create a recording of your application execution, and then load the recording into the debugger to watch the execution path. To play the recording back, you must ensure that it is played on a machine that is using the same operating system as the one that it was created on.

As your program runs, the recorder captures everything that influences the running of the program, including all input, disk access, keyboard strokes, database connections and processes, interactions with the operating system, etc. After loading the recording into the debugger, you can move forwards and backwards seamlessly through the recording.
