After reinstalling XDM, got invalid package XDB.DBMS_RESCONFIG

Hi all,I did deinsall and reinstall XDB because of some unknown WH issue that could relate to XDB.

When I verify the XDB objects I found invalid object DBMS_RESCONFIG:

SQL> alter PACKAGE XDB.DBMS_RESCONFIG compile BODY;

Warning: Package Body altered with compilation errors.

SQL> show errors
Errors for PACKAGE BODY XDB.DBMS_RESCONFIG:

LINE/COL ERROR
-------- -----------------------------------------------------------------
67/8     PL/SQL: SQL Statement ignored
69/26    PL/SQL: ORA-00932: inconsistent datatypes: expected REF got CHAR
179/8    PL/SQL: SQL Statement ignored
181/26   PL/SQL: ORA-00932: inconsistent datatypes: expected REF got CHAR

What is the cause of that datatype error?

Any help please?
