Oracle Message O2F-00326 - Some characters in this name were not legal identifier characters

ERRORSome characters in this name were not legal identifier characters
CAUSEOne or more characters in the name of a database entity could not be translated to a character that may appear in a C or C++ identifier, such as a letter, an underscore, or a digit. The characters that could not be translated were replaced with underscores.
ACTIONMake sure that the name is spelled correctly, and that it is terminated by a blank, the end of a line, or an equals sign (=). You may use the translated name with added underscores, or you may specify an explicit translation for the name in the INTYPE file.
