Unity authenticates the user on all systems listed in the session routing rule.

If any of the Teradata systems in the session routing list return a user authentication error, such as a wrong password, Unity rejects that client session on all Teradata systems.

The default Teradata database for the user must be the same on all Teradata systems. If the default user is not the same, Unity rejects the session.

If startup text is defined, it is chosen randomly from any one of the systems where the logon succeeded. Make sure that if a startup text is defined, it is the same across all systems where the user logs in.
Startup queries only run during normal logons and not when connections are opened during recovery processes.
