Are you referring to
http://download-west.oracle.com/docs/cd/B10501_01/rac.920/a96600/migrate.htm#1018519 ? (If not, I'd welcome a pointer)

"If you are converting the single-instance database files on file system to raw devices, then copy the database datafiles, control files, redo logs, and sever parameter file to their corresponding raw devices using the dd command on UNIX or the OCOPY command on Windows platforms."

I simply interpreted the OPs question differently - 'switching to raw' and 'moving to a raw partition and changing all the appropriate pointers' were different things in my mind. Thinking about it now - you're right.

No argument at all about using RMAN to do the moves. Received on Wed Sep 15 2004 - 10:02:20 CDT
