After you implement routing rules and create user mappings, you can monitor the results from Unity session list in the Unity UI or in the unityadmin command line.
All session related actions, such as stopping and aborting a session, must be performed from the Unity environment and not directly on the managed Teradata system. If you attempt to manage a session on one of the managed Teradata systems, Unity treats the action as a system failure and automatically restores the affected session to its previous state.
