So I believe your unstated point is that the only thing that needs to be reduced is Mr. E's marketing hype. ;-)

Though there has been an average increase in the total number of init parameter of 83% from
versions 7.3.4 - 9.2.0.4, the percentage of tunable/undocumented parameters has gone from 62%/38%
in 7.3.4, to 31%/69% in 9.2.0.4.

version      undoc  tunable  total  %undoc  %tunable
-------------------------------------------------------------------------
7.3.4           97      158    255      38        62    
8.1.7.4        300      204    504      60        40
9.2.0.4        587      258    845      69        31

To achieve the stated goal of 100 tunable parameters in 10g, with an expected
growth rate of 30% ( a guesstimate ) or so in the total number  of parameters, 10g
should look somthing like this:

version      undoc  tunable  total  %undoc  %tunable
-------------------------------------------------------------------------
10.0.0         999      100   1099      91         9

Larry Ellison has publicly stated that his goal is to produce a database with
less then 100 tunable parameters. Allegedly, he came rather close with 10g.
As far as 10g is concerned, I'm rather disappointed with the marketing hype
being created with oracle not making an early version available. I don't plan
on migrating to 10g until I learn it well and if some oracle sales guy
tries to exert pressure on me to migrate, he will get a very stable sign
used by English archers after the battle at Agincourt to signify that they
still have all the fingers needed to operate a longbow. I've had my fill of
white papers and articles and now I want to see the software.
