O2F-00331:

A syntactically illegal name was seen in the INTYPE file
Cause: A syntax error occurred in a name used in the INTYPE file.
Action: If the name is quoted, make sure that the quotes are at the beginning and at the end of the name. If a period (which separates a schema name from a type name) appears, make sure that the schema name and the type name are both present.
