Use the schemaFile argument to specify the fully qualified name of the schema that you want to load.
If you are loading a partial file, this may be a .scm file or a .cls file for a class or interface extract. This can also be a multiple schema file (.mul) for loading multiple schemas.
When deleting a user-defined schema (by using the optional deleteSchema argument) or loading a report view, formats, folders, users, definitions, or all report data file (by using the optional reportViewFile, reportFormatsFile, reportFoldersFile, reportUsersFile, reportDefnFile, or reportLoadAllFile argument), you do not have to specify the otherwise mandatory schemaFile. However, you must always specify the path argument.
