Home -> Community -> Mailing Lists -> Oracle-L -> RE: Oracle RAC
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.
