Poll: your oldest Oracle version

I’m doing some research for an uncoming Oracle conference – to help, please answer this poll. Thank you!

Update: thanks to everyone who voted – it certainly looks like there is a significant number of places still running Oracle versions older than 10g. It is likely that many of these will be getting ready to upgrade or be decommissioned, but even then our 7/8i/9i database skills will be relevant for some time to come.

If you haven’t voted yet, the poll is still open.
