Snippet Name: TABLESPACE: Using Raw Devices

Description: A raw device is a portion of a physical disk that Oracle uses for its database files. Raw devices are not like regular file management systems. The information they store cannot be identified or accessed by users.

A raw device is created when an extended partition is created and logical partitions are assigned to it without applying any formatting.

You can partition a raw device to store data and control files, and also use the entire raw device to store data.
