a single path. To use the load balancing feature, you must use the Direct NFS
configuration file named oranfstab, which can be placed in several locations,
depending on its scope. This file has syntax to define multiple physical IP addresses
(path) for a given NFS server (server). For example, this entry in oranfstab indicates
three physical interfaces on the same network (net mask 255.255.255.0) to
NFSServer1:
server: NFSServer1
path: 132.34.34.12
path: 132.34.34.13
path: 132.34.34.14
export: /vol/oradata1 mount: /u01/oradata1
The 11.1.0.7 release introduces a new parameter for oranfstab. The parameter,
called “local”, lets you specify outbound paths from the Oracle server to the NFS
server. For example, on this same system you might have the following oranfstab
entry with two outbound NIC ports:
server: NFSServer1
local: 132.34.34.21
local: 132.34.34.22
path: 132.34.34.12
path: 132.34.34.13
path: 132.34.34.14
export: /vol/oradata1 mount: /u01/oradata1
If you are using a shared Oracle home and you have placed oranfstab in a shared
location, what is indicated in “local” will be common to all Oracle servers sharing
the Oracle home. Obviously, using a hard-coded local IP address will not work in
this case. You can use a generic entry for the local path (e.g., localhost1), and then
define the actual IP address in your /etc/hosts file. This way, the path name can
be the same for all servers (localhost1), but the IP address can be different for each
server in /etc/hosts.
The /etc/hosts file for Oracle server, server 1 (having IP addresses 132.34.34.21
and 32.34.34.22) contains this:
132.34.34.21 localpath1.customer.com localpath1
132.34.34.22 localpath2.customer.com localpath2
The /etc/hosts file for Oracle server, server 2 (having IP addresses 132.34.34.31
and 132.34.34.32) contains this:
132.34.34.31 localpath2.customer.com localpath1
132.34.34.32 localpath2.customer.com localpath2
Since Direct NFS is used only to access data files, it is not necessary to indicate the
vNFS host used for Oracle_Home in the oranfstab configuration file. Your System
