Oracle DNFS (Direct Network File System) is a solution provided by Oracle to access NFS located in NAS. It makes the integration of NFS and DB easier and optimal. This direct integration provides performance improvements with fast and scalable access. This article explains the activation of DNFS and the cloning of the Oracle DNFS database.<\/p>\n

Activating DNFS (Direct Network File System)<\/h2>\n

Use the operating system to c<\/span>reate the ZFS Storage, User and Group IDs.<\/p>\n

Enable DNFS on database servers (on specific nodes in a Real Application Environment); this article describes how to open a backup taken from an RAC server consisting of 2 nodes, as a single instance.<\/p>\n
