I believe that the reason for not locating "regular files" such as you $ORACLE_BASE and $ORACLE_HOME trees on OCFS stems from the fact that when the database opens a file on OCFS it uses the o_direct flag. When a file is opened with o_direct regular file access is not permitted. You might want to take a look at patches 2883583 and 2913284. These contain o_direct enabled file utilities like dd, cp, tar etc. If you're not doing a production implementation, you might want to take a look at the OCFS2 Beta4, it's available from http://oss.oracle.com/projects/ocfs2/ The new version offers a lot more flexibility management wise than the previous version. You might also want to take a look at Polyserve as an alternative to OCFS. I've been quite impressed with their CFS.
