Hi!
Not only file headers are affected by big-little
endian problem AFAIK, whole contents of files themselves are as well (multibyte
char data for example).
But in 10g you need RMAN to convert files from one
endian format to another.

yes in 10g ?
Hmm.
Quoting Page 2 of http://otn.oracle.com/products/database/oracle10g/pdf/OW_General_OracleDatabase10G_Revolution_10R1_081903.pdf
"To assist in migrating to Enterprise Grid Computing,
Oracle Database 10g
enables very high-speed movement of
data from one database to another across platforms and database versions.
For highest performance, transportable tablespaces move data at the
datafile level for fast �plug-and-play�. Transportable tablespaces can now
operate across platforms. Among other things, this allows databases to be
migrated to a new platform at the speed of file transfer."

Cloning
from one OS to another simply doesn't work because the file
header formats are different between the different OS's. You can't
just copy a datafile from Linux to Solaris, for example, and expect to
read it.

I don't see how this would work. You still have to move
the physical data file to the new machine. What makes a transportable
tablespace trasportable is that you notify the data dictionary of the
move.
If this works, couldn't you just clone from one OS to another
by copying dbf files? Thinking out loud here, a clone would include a few
things not in transportable tablespaces: redo logs, control files, rbs
tspace, system tspace. Control files can be rebuilt, redo logs aren't
necessary with a clean shutdown (you can recreate the shell. Data doesn't
matter). Would the physical structure of SYSTEM and RBS be that
different??? Hmmm...
Any
thoughts?

I have heard rumors that the 10g
tweak on transportable is to allow you to move cross-platform. Rumors
only, I have NO inside information!
