O2I-00126:

You must specify an INTYPE file with SCHEMA_NAMES=FROM_INTYPE
Cause: The option SCHEMA_NAMES=FROM_INTYPE requests that schema names be written to the OUTTYPE file as given in the INTYPE file. However, an INTYPE file was not specified.
Action: Either supply the name of an INTYPE file, or specify the SCHEMA_NAMES option ALWAYS or IF_NEEDED.
