Oracle Disk Manager Network File System Management
Oracle Disk Manager (ODM) can manage network file systems (NFS) on its own, without using the operating system kernel NFS driver. This is referred to as Direct NFS. Direct NFS implements NFS version 3 protocol within the Oracle Database kernel. This change enables monitoring of NFS status using the ODM interface. The Oracle Database kernel driver tunes itself to obtain optimal use of available resources.
