server

The NFS server name.

path

Up to four network paths to the NFS server, specified either by internet protocol (IP) address, or by name, as displayed using the ifconfig command on the NFS server.

local

Up to 4 paths on the database host, specified by IP address or by name, as displayed using the ipconfig command on the database host.

export

The exported path from the NFS server. Use a UNIX-style path.

mount

The corresponding local mount point for the exported volume. The path can use a Windows-style path, or the following path formats:

• nfs://server/export/path/file

• server:/export/path/file

• //server/export/path/file

mnt_timeout

(Optional) The time (in seconds) for which Direct NFS Client should wait for a successful mount before timing out. The default timeout is 10 minutes (600).

uid

(Optional) The UNIX user ID to be used by Direct NFS Client to access all NFS servers listed in oranfstab. The default value is uid:65534, which corresponds to user:nobody on the NFS server.

gid

(Optional) The UNIX group ID to be used by Direct NFS Client to access all NFS servers listed in oranfstab. The default value is gid:65534, which corresponds to group:nogroup on the NFS server.

nfs_version

(Optional) The NFS protocol version used by the Direct NFS Client. Possible values are NFSv3, NFSv4, and NFSv4.1, and pNFS. The default version is NFSv3. To specify NFSv4.x, then you must configure the nfs_version parameter accordingly in the oranfstab file. Specify nfs_version as pNFS, if you want to use Direct NFS with Parallel NFS.

security_default

(Optional) The default security mode applicable for all the exported NFS server paths for a server entry. sys is the default value. See the description of the security parameter for the supported security levels for the security_default parameter.

security

(Optional) The security level, if you want to enable security using Kerberos authentication protocol with Direct NFS Client. This parameter can be specified per export-mount pair. The supported security levels for the security_default and security parameters are:

• sys: UNIX level security AUTH_UNIX authentication based on user identifier (UID) and group identifier (GID) values. This is the default value for security parameters.

• krb5: Direct NFS runs with plain Kerberos authentication. Server is authenticated as the real server which it claims to be.

• krb5i: Direct NFS runs with Kerberos authentication and NFS integrity. Server is authenticated and each of the message transfers is checked for integrity.

• krb5p: Direct NFS runs with Kerberos authentication and NFS privacy. Server is authenticated, and all data is completely encrypted.

The security parameter, if specified, takes precedence over the security_default parameter. If neither of these parameters are specified, then sys is the default authentication.

For NFS server Kerberos security setup, review the relevant NFS server documentation. For Kerberos client setup, review the relevant operating system documentation.

management

Enables Direct NFS Client to use the management interface for SNMP queries. You can use this parameter if SNMP is running on separate management interfaces on the NFS server. The default value is server.

community

The community string for use in SNMP queries. Default value is public.
