Okay,

I found this by accident ...

I was trying to get explain plan on a query that involved a in-line-query that selects from financials database. This in-line query was alias'd as "A". Current cost of query was ~2800.

So, to test for explain plan I added hint

/*+ diving_site(A) */ -- note the spelling mistake here ... the cost of the query changed to 25. I corrected the spelling mistake and make it driving_site, cost went back to ~2900.

Has anyone experienced this before? Our original db is 9202 and financials is on a RBO, 805 db accessed through a db_link.
