Overview of ReFS File System

The ReFS prevents corruption of the file metadata that occurs in standard NTFS volumes which makes data inaccessible.

This release supports Oracle Database installation on Resilient File System (ReFS). ReFS uses checksums for file metadata, and an allocate-on-write method to update data which minimizes the risk of corruption.

ReFS supports volumes from 256 zettabytes to a maximum of 4 petabytes. ReFS stores and protects data from common errors that cause data loss. ReFS is resilient to power outages. ReFS also protects data based on volumes, directory, and files.

Setting File Permissions

Oracle Universal Installer, Oracle Database Configuration Assistant, and Oracle Database Upgrade Assistant set file permissions when Oracle Database software is installed or upgraded.
