Marvin,

You have inadvertently stumbled into a "RELIGOUS" issue.

If you look in the Oracle Performance Tuning Guide (small pamphlet
that comes with the three books they deign to send) you will find
contradictory statements regarding raw partitions.

I personally prefer file systems.  If Oracle could sell a file system 
manager, they would.  I do not trust that blocks are written without 
a parity check.

However, if you need parallel Server you are stuck , well maybe stuck.  On EMC drives
you may get around the requirement for raw partions.

Eyal Aronnof of Quest Software has done a study of this from a conversation I
had with him a year ago.  If I remember correctly he was getting fantastic
times from striped file system (LVM)  
contact Gil Asherie gil_at_quests.com he may be able to confirm.
