Database Overall → Direct NFS
The NFS_VERSION parameter allows the user to specify the NFS protocol to be used by Direct NFS Client. Possible values are nfsv3, nfsv4, and nfsv4.1. If no version is specified, nfsv3 is used by default.
Business Benefit: NFS Version 4 provides performance advantages over NFS Version 3, and the NFS_VERSION parameter allows the user to take advantage of those capabilities when available.
