Interactive Debugging of an Orchestration in HAT

To perform interactive debugging of an orchestration in HAT, you must deploy and execute at least one instance of the orchestration you want to debug. To do so, you will have to perform the following steps:

1. Deploy and execute the orchestration you want to debug at least once. This will generate an instance of the orchestration that you can attach to in HAT. Without this step, HAT will not know about your orchestration and will not have a way to display it.

2. View the orchestration in the Orchestration Debugger by executing one of the canned queries or by running a custom query. This exposes the orchestration so that you can set class-level breakpoints.

3. Set a class-level breakpoint on the orchestration shapes you are interested in debugging. Future instances of the orchestration will break at the shapes specified.

4. Generate one or more new orchestration instances by submitting appropriate messages. You should use messages that exercise the appropriate shapes in the orchestration. For example, if you have a decision shape, make sure your sample message will trigger the branch you are interested in.

5. Attach to the orchestration instance by using Debug | Attach.

6. Review variable names and values including message part contents.

7. Resume the orchestration. If no more breakpoints are encountered, the debugger will detach from the instance.

8. Remove class-level breakpoints.
