We too are using Raw devices to administrate a 200+ Gb database. While performance improvements have been recognized on our system in this past, the present and future implementation of RAID technologies are proving to pull their weight as well.
For the most part, we have associated symbolic links to provided the bridge
between Oracle and the physical devices, in other words, it is the symbolic
links which are used as the filename. In this respect problems can occur such
as inadvertently having two distinct links (ie. database file names) pointing
to
the same RAW devices. Since the two names are not the same Oracle is happy,
that is until is needs to read/write from the physical device. You now have
serious problems. How do I know this...guess !
I can provide more details if you wish. Best of luck
