Hi, I have searched metalink and found very few documents related to the error: ORACLE CLUSTER REGISTRY CAN EXIST ONLY AS A SHARED FILE SYSTEM FILE but none of them were related to my issue. Could someone please tell me if my configuration would work: oracle_base=/u01/app/oracle (non shared, available on both host 1 and host 2) I read on puschitz's oracle 9i and 10g rac installation that it is better than OUI decides oracle_home. Hence I have left it unset for now. ora_crs_home=/u01/app/oracle/product/crs (non shared, available on both host 1 and host 2) /u01 is not shared. I have shared /u02 for datafiles, voting disk and OCR. These are my settings. I use iscsi to simulate shared disk and have used OCFS2 for cluster file system. your comments please. I'm following: http://www.dbasupport.com/oracle/ora10g/RAC_9i_to_10g02.shtml and puschitz 10g rac installation to upgrade from 9.2.0.8 to 10.1 Thanks in advance.
