Re: Why "Separating Data and Indexes improves performance" is a myth?

I believe Stephan Haisley has built a 9i database
with a 7.5K block size (not for production reasons,
of course).

There is an argument for using a (slightly) unusual size
block if your main purpose is to handles large numbers
of uniformly sized LOBs. Whether it would work or not
is something to be investigated.

I don't think you can even create a tablespace with a blocksize that's =
not a power of 2 with Oracle 9.0 or higher, but I can tell you that an =
8.1 database with a blocksize of 3K and a locally managed autoallocate =
tablespace makes for some amusing ORA-600s.
