Peter,

Yes it works with Clustered file system but you have to spend extra dollars to buy the product. I am aware of Clustered file system. You can get more information from the following website:

Sorry, fundamental error in this.  RAC DOES work with clustered file system=
s as well, and has NEVER required raw files under real operating systems li=
ke VMS.  The raw requirement is purely and simply a Unix limitation, since =
*nix can't share file systems without it until you get to the clustered fil=

e systems that have recently come out.

Pawan,

We have AIX (5.2), EMC storage, Oracle9i (9.2.0.5.0) RAC (3 nodes). Yes, R= AC works only with RAW files. =

I use RMAN to backup Production database.  I create development database us=
ing Production backup(done by RMAN) in NON-RAC system.  All my development =
databases are using FILE SYSTEM (not RAW).  RMAN backup is done at block-le=
vel therefore it does not matter whether you are backing up RAW datafiles o=

r FILE SYSTEM datafiles.

Since RAW files name are not Oracle standand, I have created a SOFT LINK to= create datafiles. For example:

RAW FILE:

	/dev/sys1_1024m
	/dev/rsys1_1024m

DATAFILE (Soft Link):

$ ln -s /dev/rsys1_1024m /u01/oracle/oradata/prod/prod_raw_system_1_1024m.= dbf

Now my datafile name in Production database is /u01/oracle/oradata/prod/pro= d_raw_system_1_1024m.dbf.

I strongly advise you to put the size in RAW file name because you can not = find out the size of RAW file.

I am using OEM, you do not need any third party software. You have to know= lot of GV$ views.
