The use of raw devices makes limitations of ext2fs unimportant; if
you use a raw device, you won't have a filesystem on it. Typically
Oracle can run with either a file or a raw device. The raw device
is accessed with open(2), read(2), and write(2), and thus depends
only on the block disk device driver.

Yeah, this is great: now we have an application that can make
even FreeBSD look slow. ;^)

A friend of mine is a sysadmin at a big HP and Oracle shop. One
organization developed an application using NT and MS-SQL Server,
because they thought they were going to save a ton of money.
When they fielded it, it didn't last three hours under the load
thrown at it. They ended up redeveloping it on Oracle and HP-UX,
and moving it to a part of a server owned by another group.
Oracle on an Pentium 200 or K6 probably could have handled their
load, they had a max of 12 users poking at the database. ;^)

I'm anxious to try it under Linux emulation. I'll probably poke
and prod at the demo version for a little while; I've got an
OpenLinux 1.2 system at work to hack on if needed.
