How to resolve error ORA-29491: invalid table for chunking?

Question

Hello,
I'm trying to implement DBMS_PARALLEL_EXECUTE to speed up a huge update I need to do. I'm stuck on a problem with the table I'm using to test my procedure. Here's a simple test that produces the same error. As best I can tell, the table I'm declaring here is missing some kind of requirement that lets DBMS_PARALLEL_EXECUTE make use of it, but the docs and searching for the error code haven't turned up any useful discussions. Please help.
drop table owner.why_cant_i_hold;
create table owner.why_cant_i_hold (
things VARCHAR2 (64),
amount INT,
CONSTRAINT why_cant_i_pk PRIMARY KEY (things)
insert into why_cant_i_hold values ('limes', 8);
insert into why_cant_i_hold values ('lemons', 8);
insert into why_cant_i_hold values ('watermelons', 5);
insert into why_cant_i_hold values ('cats', 4);
insert into why_cant_i_hold values ('teacups',10);
insert into why_cant_i_hold values ('mugs', 5);
insert into why_cant_i_hold values ('eggs', 15);
insert into why_cant_i_hold values ('jobs', 3);
commit;
-- got tasks?
COLUMN task_name FORMAT A10
SELECT task_name,
status
FROM user_parallel_execute_tasks;
--exec DBMS_PARALLEL_EXECUTE.CREATE_TASK('holding');
exec DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('holding', 'ODDEV03', 'why_cant_i_hold', true, 3);
It seems like a really simple case here. The output is all successful until
"Error starting at line 25 in command:
exec DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('holding', 'owner', 'why_cant_i_hold', true, 3);
Error report:
ORA-29491: invalid table for chunking
ORA-06512: at "SYS.DBMS_PARALLEL_EXECUTE", line 27
ORA-06512: at "SYS.DBMS_PARALLEL_EXECUTE", line 121
ORA-06512: at line 1"

Answer 1

Oh. This was an easy one, table names are never really lower-case. Changing the value in my chunking call fixed the simple test:
exec DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('holding', 'ODDEV03', 'WHY_CANT_I_HOLD', true, 3);
It doesn't help with why my more complicated test case isn't working, but I have details to check before I ask again.
EDIT: lesson learned... 'invalid table' doesn't mean the database can find the table you are talking about at all. I hope that's a help.
