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=oracle owner=oracle 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.
