Thanks for the note on 6.0.27. It's funny how things are introduced early in releases sometimes. OPS was in 5, CBO in 6, some waits in 6 (the x$trace stuff). And it's all still around in 9 :-))).

However, Mogens is correct in that it was first officially released and supported in the first Production release of Oracle7, 7.0.13.

Seems to me it was introduced in 7.2. I'm sure Mogens knows for sure. :)
