Of course they are not.  I'm simply trying to understand the capabilities
and limitations of the Oracle cluster filesystem.  With an NFS mounted
filesystem, you can have two servers mount the same volume and perform
simultaneous reads/writes while the NFS mechanism takes care of locking,
etc.  This scenario works fine for a mailserver.

My question is can two non-clustered servers, or two non-clustered
applications, mount the same OFCS2 volume and perform simultaneous
reads/writes without fear of data corruption on the volume?
