Explain plan/autotrace for stored procedure

Question

Hello,
I have an stored procedure executing a select statement. I would like to use autotrace or explain plan or something to check how my select statement is executed.
So far I've only accomplished to use autotrace on statements i write in sql*plus. The problem here is that my select statement uses some user defined types (lists of numbers and dates). Also if possible I would like my application to call the procedure providing the parameters. I feel kind of lost here.
My query is something like this:
int_list list_of_numbers;
int_list2 list_of_numbers;
date_list list_of_dates;
select * from table1, table(int_list) i1, table(int_list2) i2, table(date_list) d1 where ....

Answer 1

No, i do not have a "close cursor" procedure, but I just leave the tracing on for now. When in production I will turn it off.
This is just a test system so I have full control over everything.
Yes, I granted execute on dbms_session and alter session to my user, because I received an error when trying to execute the stored procedure. But with dbms_support and monitor I can't even compile my stored procedure.
I granted execute on dbms_monitor to my user and the procedure compiled fine! When trying to grant execute on dbms_support sql*plus complained on not even finding that package/procedure/whatever.
Thank you for all your help!
