Hints on object

Question

Hi All,
Can I use Oracle hints on object data? I'm using 10.2 version.
Sample SQL:
SELECT /*+ parallel(a,10) parallel(b,10)*/ Obj(a.#col1#,
a.#col2#,
) BULK COLLECT
INTO < Variable_Name >
FROM TABLE(CAST(#obj1# AS #obj1_Tt#)) a,
TABLE(CAST(#obj2# AS #obj2_Tt#)) b
WHERE < Filter Goes Here >
GROUP BY < GROUP BY Conditions Goes Here>
Thanks,

What are you actually trying to achieve?
Hints are a great tool for helping to locate the cause of performance issues, but they are something that should be rarely used in production code. Oracle provides other tools that also assist with finding performance issues without the need to use hints.
Perhaps if you explained what your business requirements are we can advise how to approach it.
