Do not use database SYSUDTLIB as the target database name in a COPY statement. Using SYSUDTLIB as the source database in a COPY FROM statement is allowed, but specifying a target database name that is different than SYSUDTLIB is required. This allows SYSUDTLIB to be copied from a source system to a different database on a target system. When used as the source database in a COPY FROM statement, database SYSUDTLIB is not linked to database DBC. Therefore, only database SYSUDTLIB is copied.
