When database DBC is restored, Teradata ARC automatically restores database SYSUDTLIB and its UDT definitions. DBC is always restored first and SYSUDTLIB restored second, before any other objects are restored. Do not restore SYSUDTLIB as a separate object.
Using the EXCLUDE option to exclude DBC on a RESTORE statement excludes SYSUDTLIB also.
Refer to Restoring the Database DBC for specific instructions on restoring database DBC.
