The plan that I see in v$sql_plan appears to be different from what I see
in explain plan. There is an article on
metalink that deals with this issue. The thing that I don't understand is
that the plan I see in s$sql_plan seems to
be the same as the plan for the query that finishes in seconds. Yet, this
one runs for over an hour

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
