Cause:
unpublished Bug 9694190 "11.2.0.1 UPGRADE TO 11.2.0.2 ODM BECOMES INVALID WITH A FEW INVALID PACKAGE BODIES"

Solution:
SQL> CONNECT / AS SYSDBA;
SQL> DROP USER DMSYS CASCASE;
SQL> DELETE FROM SYS.EXPPKGACT$ WHERE SCHEMA = 'DMSYS';
SQL> SELECT COUNT(*) FROM DBA_SYNONYMS WHERE TABLE_OWNER = 'DMSYS';

If the above SQL returns non-zero rows, create and run a SQL script as shown in the following example:

SQL> SET HEAD OFF
SQL> SPOOL /DROP_DMSYS_SYNONYMS.SQL
SQL> SELECT 'Drop public synonym ' || SYNONYM_NAME || ' ;'
FROM DBA_SYNONYMS WHERE TABLE_OWNER = 'DMSYS';
SQL> SPOOL OFF
SQL> @/DROP_DMSYS_SYNONYMS.SQL
SQL> EXIT;
