Okay. Here's one for you.
I"m at the Hotsos Performance Tuning Symposium (probably 2003), the add-on dy with Steve Adams. Someone (probably Mark Bobak) mentions that Steve is connected as sys and not with an unprivileged account. There was some relevance as to how something would run differently while connected as user sys.
Steve's response was - that he always connected as sys. That's typically the schema that he was working in. And for research and development of what he was working on - on a single user database on a laptop, it was appropriate. Elsewhere, it most likely would not be.
I faintly recall having to restore and re-run an upgrade of a dev db that had the ixora views installed into it. those were not something that you'd want to leave lying around come upgrade time. really hosed things.
Highly informative session, though. lots of "ums" and block dumps.
Didn't keep track of which had a higher count, but there were well
over 200 block dumps.
Never really did fully implement the use of single table hash clusters. Was really fired up to do so after the session.
Maybe in 11g.
