Yes, you are right. The plan I got from sql_plan is different from the one
I got via explain plan.

Well,
you better get the plan from v$sql_plan, as the explain plan does not do
bind-peeking (when you use the cursor_sharing=force setting). so the plan
given by explain can be different from what you have when you actually
execute the statement (depeding on bind values, whether this is the first
time you execute the statement or not , and the presence of histograms)

No. I am using the following to get the explain plan:

select plan_table_output from
table(dbms_xplan.display('PLAN_TABLE',null,'ALL')) (found it on metalink)

thank you

Did you checked in v$sql_plan the real execution plan with
CURSOR_SHARING_EXACT ?

    Hi all:

    Can someone recommend a good article on the cursor sharing in
Oracle
    9. I
    just found a query that runs in 5 seconds
     with CURSOR_SHARING_EXACT and in more than 1 hour without it
    (cursor_sharing is set to force on the DB level)

    I'm trying to find out why it happens.

    thank you
