how Oracle works, and how to go about fixing performance problems.
If though you consider

I'm going to take some exception to what Cary has said on the subject, but I
believe in the end she'll agree with me.
LIO's are inherently cheaper than PIO's simply because you have to complete
the LIO before asking for a PIO. And no you can't work with data that has

She? Cary, you didn't tell us about this surgery ;-)
Dick, last time I saw Cary (October) he was very masculin. I bet this
SORRY!! Regrettably e-mail does not provide the required info, namely a picture. The

Why do people still talk about THE
buffer cache hit ratio ? There are lots
of them.

the ones you can get from v$buffer_pool_statistics,
and the ones you can get from v$segstat.

Rich,
Burn any source that talks about hit ratio's.
What exactly is running slow in your system and at what times ?
Talk directly to the user that is experiencing the slowdown and ask them
to repeat the behavior.
Set a 10046 trace and go find the slowdown while
Erm...sorry. I said :) when I should've said ;). Joke. Pun.
Tongue-in-cheek. Yer built too low. The fast ones keep going over
your head. Gotta keep your eye on the ball. Eye. Ball. That's
a joke there, son.
Again, sorry. We're in no change mode until after the Holidaze and
Foghorn
Rich,
you mean due to 'no change mode' you can't even change your hit ratio ... too bad.
Happy holidays everyone !!
