I liked the O'Reilly book, but don't know if they updated it for 8i - time
to do it soon, if it hasn't been done! 9i is coming this summer...

Subject: RE: OT: Reading the Oracle Tea Leaves
Well, we run lots (70 odd) of smallish (4-16Gb) databases that
usually don't
need a lot of tuning. Hence, if we do have to tune something, its a
real
pain because we don't have the experience of doing it every day.
So, as far
as I'm concerned, roll on autotuning. There's plenty to keep us
occupied at
'higher' levels.
However, on the 'career' front, I'd like to learn more, so could
anybody
recommend a good book on tuning?
TIA

I didn't assert that DBA's will become expendable, nor did I state a
timeframe for when autotuning will become a usable option. I doubt
autotuning will ever be perfect, but any DBA who thinks he is, has a
vainglorious opinion if himself.
I believe in the fullness of time, between 5 and 10 years,
autotuning will
be good enough for at least 80% of the Oracle databases. We tune
based on
our expericences and on the experiences of others. Many of these
experiences could be codified as rules. We also fine tune our
"rules" or
derive new ones as new situations arise. I doubt autotuning will be
doing
the five or ten year period.
If you think autotuning is a death knell, keep in mind here is more
to being
a DBA than changing init.ora parameters and that the skillset
required will
change over time.

I foresee the database being sold as a turn key product configured
by Oracle
at a reduced price. In order to receive the discount the purchaser
would
have to agree not to mess with the init<SID>.ora parameters, nor
take any
action which would enable or disable any database options. "What?!,
not
change init.ora parameters", you scoff. Remember that Oracle 9i has
some
autotuning capability. I expect, at first, autotuning will not work
as
advertised, but over time will mature into a powerful product.
