There are many things that people do to Oracle systems to try to improve performance – adding hardware, tweaking parameters, adding indexes, changing block sizes, tuning the SQL.
When all else fails, you might even consider shouting at it – but don’t, it won’t work, as demonstrated in this video clip.
Thanks to Oak Table member Mario Broodbakker for sending me the link.
Incredible…
But looking the other way around: if your rack is in a very noisy room than you can have bad performance!
Incredible…

lascoltodelvenerdi,
If you read through all the comments attached to that posting, you’ll see various ideas about exactly why the scream had the effect it did; and some observations about the known impact of noise (viz: vibration) on disc drives and how manufacturers of the discs and racks go about minimising the impact of “steady state” noise.
