ORA-21700 in re-creating ADT for OLAP_TABLE

Question

I'm trying to create a script that can automate the process of generating abstract data types for use in an OLAP_TABLE function. I'm following the examples in the documentation. Everything runs great the FIRST time I run my script, but when I drop my types and re-create them, when I run the next SELECT statement against the OLAP_TABLE function, I get:
ERROR at line 1:
ORA-21700: object does not exist or is marked for delete
My script drops the ADTs before creating, but somehow they are not REALLY being dropped.
SET ECHO ON
SET SERVEROUT ON
DROP TYPE ts_table_6;
DROP TYPE ts_row6;
CREATE TYPE ts_row6 AS OBJECT(
CONJ2002 VARCHAR2(400),
CONJ2002_DATA number(16),
PERIOD VARCHAR2(10),
PERIOD_NAME VARCHAR2(20));
CREATE TYPE ts_table_6 AS TABLE OF ts_row6;
SELECT CONJ2002, period, period_name, conj2002_data FROM TABLE(OLAP_TABLE(
'REFVLMTA DURATION QUERY',
'ts_table_6',
'limit CONJ2002 to first 3',
'MEASURE CONJ2002_DATA from CONJ2002.DATA
DIMENSION CONJ2002 from CONJ2002
DIMENSION PERIOD from PERIOD WITH
ATTRIBUTE PERIOD_NAME from period.name'));
Again, it works the first time, but not the second time. I need to bump up the ADT names to ts_row7 and ts_table_7. SQL Plus says the types are being dropped.
Any ideas?

This could be a caching problem and the recourse is to reinitialize the referencing object. You can flush the SQL library cache with the following command:
alter system flush shared_pool;
Also, you might want to use the force phase of the drop type command:
drop type ts_table_6 force;
drop type ts_row_6 force;
If these solutions do not work, please contact Oracle Support. This may be a bug.
