Hi Friends,

I have oracle 9i database running on RAC (raw disks) and want to migrate the data from the raw disks to file systems. How can I proceed?

Thx

What is a raw device?

A raw device, also known as a raw partition, is a disk partition that is
not mounted and written to via the UNIX filesystem, but is accessed via
a character-special device driver; it is up to the application how the
data is written, since there is no filesystem to do this on the
application's behalf.

You can move your data by using different ORACLE utilities.
1:IMPORT/EXPORT
2:RMAN (by using DB_FILE_NAME_CONERT/REDO_FILE_NAME_CONVERT)
3:DBCA (TEMPLATE choose option WITH DATA AND DIFFERENT FILE SYSTEM)

2:RMAN (by using DB_FILE_NAME_CONERT/REDO_FILE_NAME_CONVERT)

It is "LOG_FILE_NAME_CONVERT" parameter.
