Recommended File System

Oracle strongly recommends that you install the Oracle Database Client home (Oracle database binaries, trace files, and so on) on Oracle ACFS, NTFS, or ReFS; the database files themselves must be placed on Oracle ASM if using Oracle ACFS; otherwise they can be placed on NTFS, or ReFS.

Oracle recommends that you use Oracle ACFS, Oracle ASM, NTFS or ReFS to ensure security of these files.
