A colleague sent me an interesting note today. Specifically, Metalink Note 578455.1, which announces that Oracle
12g 12c will not support raw volumes for Datafiles, controlfiles, redo logs, OR voting disks and OCR.
Those of us acquainted with RAC might be shouting “WHAT?!?!” at about this time. This is because without raw volumes, our only choices for OCR and voting disk placement seems to be a CFS (such as OCFS).
However, wording in the Metalink note indicates that ASM will be able to support the OCR and voting disk (“and other database files”) in 12c. The note hints at broader support for NFS in 12c as well.
