Details

In release 11.2, the Oracle installer and DBCA (Database configuration assistant) will no longer support raw/block devices for database files. . In addition, there will no longer be raw/block device support for storing the OCR and Voting Disks for new installs. Customers who create a new 11.2 database will need to store their database files in either ASM, a file system, or on an NFS filer. RAC database files must be stored on ASM, a certified clustered file system, or a certifed NFS filer.  OCR and Voting Disks must be stored on ASM or a certified NFS filer.

Customers who upgrade an 11.1 or earlier database stored on RAW/Block devices will be able to continue to store their database files on RAW/Block devices. The restriction on RAW/Block devices only applies to new databases created via DBCA. In addition, Enterprise Manager will fully support an upgraded 11.2 database with files stored on RAW, including the ability to create and move files on RAW.

Actions

Customers who wish to create 11.2 databases on RAW must use the command line interfaces to create datafiles on RAW (i.e., CREATE DATABASE/TABLESPACE). Alternatively, they can create an 11.1 database and upgrade it to 11.2.

Oracle plans to fully desupport RAW/Block device storage effective with the next major release following 11.2. At this time, customers will need to migrate any data files stored on RAW/Block devices to ASM, a cluster file system, or NFS. Thus, we recommend new databases not be deployed on RAW/Block devices.
