SYS.ODCIARGDESC, ODCICOLINFO, ODCICOST, ODCIINDEXINFO

 I am preparing to upgrade a database from 9.2.0.8 to 10.2.0.4.  The prep utility (utlu102i.sql) says that there are five objects owned by sys that are invalid.  I checked DBA_OBJECTS, and there are four types that are invalid:

ODCIARGDESC

ODCICOLINFO

ODCICOST

ODCIINDEXINFO

Can anyone tell me what these types are related to, and how to make them valid?  A simple

alter type sys.odciargdesc compile;

does not work.
