Subject: oracle can ignore hints

We had a discussion on here regarding hints. some of you stated that Oracle cannot ignore a proper hint. I have a TAR open and asked about this. Here is the response.

"A hint simply adds weight to a cost estimation, it can still be overridden by the CBO if the values aren't seen as useful."
