To locate, view, and handle failed events, use Flow Manager, a tool that is installed with the IBM WebSphere InterChange Server Express product. Flow Manager allows you to easily construct a query to locate and display unresolved flows. After you display the unresolved flows, you can select any flow in the display and choose to submit it, discard it, or perform other actions.
