Hi Tim,

Went to a management meeting the other day to discuss the statuses of a number of projects.

At the meeting I asked the assembled managers "Hey guys, what are your opinions on what type of Oracle optimizer we should use ?"

They kinda looked at me with a glazed look in their eyes and one of them was brave enough to ask "What's an optimizer ?".

OK, it's not entirely true but I were (stupid enough) to ask the question, I'm sure it's the reaction I would receive, if not a lot worse.

Can't say I've (yet) worked in an organisation where management decides how to tune the databases !!

Cheers

Richard
