Oracle 12c, Desupport for Raw Storage Devices

Oracle 11g 때부터 raw device를 지원한다, 안한다 이야기가 많더니만,

드디어 Oracle 12c에서는 지원하지 않는다는 문장이 메뉴얼에 등장했네요. 

8.1.10.1 About Upgrading Oracle Database Release 10.2 or 11.1 and OCFS and RAW Devices

If you are upgrading an Oracle Database release 10.2.0.5 or release 11.1.0.7 environment that stores Oracle Clusterware files on OCFS on Windows or RAW devices, then you cannot directly upgrade to Oracle Database 12c. You must first perform an interim upgrade to Oracle Database release 11.2 and migrate the Oracle Clusterware files to Oracle Automatic Storage Management (Oracle ASM). Then you can upgrade from release 11.2 to Oracle Database 12c.

8.1.12 Desupport for Raw Storage Devices

Starting with Oracle Database 12c, block file storage on raw devices is not supported. You must migrate any data files stored on raw devices to Oracle ASM, a cluster file system, or Network File System (NFS).

This also affects the OCR and voting files for Oracle Clusterware. You cannot store the OCR or voting files on raw devices. Oracle Clusterware files must be moved to Oracle ASM before upgrading.
