Certain Teradata configuration parameters must be set to be the same across all systems to be managed by Unity. The Unity Compatibility Advisor can be used to discover differences between Teradata Database systems that can affect the behavior of Unity. The configuration parameter list that must be the same across systems includes:
- The same character sets must be installed and available on all systems.
- The default character set must be the same on all Teradata Database and Unity systems.
- The same User Defined Types must be installed on all systems.
- All Teradata Database systems and connected Unity server(s) must have the same authentication mechanisms, which must be similarly configured to operate in a Unity environment. See Security Administration.
- All users that will connect through Unity must be valid, each user must have the same Teradata password and have the same default database across all systems.
- The following database control settings must be the same across all Teradata Database systems and Unity repositories:
- HashFuncDBC - This value must also be the same as the Unity HashFuncDBC parameter value.

- FixSRandomRange - Teradata Systems below 14.10.02 do not have a FixSRandomRange setting.If Unity is managing at least one Teradata system with a version less than 14.10.02, FixSRandomRange must be set to FALSE for all managed Teradata systems that have the setting configurable.
