About raw volumes versus CFS for data files

Keep these points in mind about raw volumes and CFS for data files:

• If you use file-system-based data files, the file systems containing these files must be located on shared disks. Create the same file system mount point on each node.
• If you use raw devices, such as VxVM volumes, set the permissions for the volumes to be owned permanently by the database account. For example, type:

  # vxedit -g dgname set group=dba owner=dba mode 660 \
/dev/vx/rdsk/dgname/volume_name

  VxVM sets volume permissions on import. The VxVM volume, and any file system that is created in it, must be owned by the Oracle database account.
