关于linux /etc/sysconfig/network中的NOZEROCONF=yes参数

关于linux /etc/sysconfig/network中的NOZEROCONF=yes参数

今天从CSSD Fails to Join the Cluster After Private Network Recovered if avahi Daemon is up and Running (Doc ID 1501093.1)文章中看到了这个参数，
在该文章中，有如下的论述：

Solution

The solution is to shutdown and disable 3rd party zeroconf mDNS process, in this case, avahi-daemon
To shut it down, as root:

# /etc/init.d/avahi-daemon stop

To disable it, as root:

# /sbin/chkconfig  avahi-daemon off

On Oracle Linux/Redhat Linux, "NOZEROCONF=yes" must be included in /etc/sysconfig/network

另外，如下的文章介绍了该参数：
How To Prevent Bogus Entry 169.254.0.0/255.255.0.0 Automatically Added To Routing Table (Doc ID 1161144.1)
在该文章中，有如下的描述：

The route entry "169.254.0.0/16" is the IPV4 "link local" block.It is allocated for communication between hosts on a single link. Hosts obtain these addresses by auto-configuration, such as when a DHCP server may not be found.

This routing entry is added automatically because RHEL/OEL enable Zero configuration networking(zeroconf) by default.

To disable the zeroconf route during system boot or network service restart,
 edit the /etc/sysconfig/network file and add the following NOZEROCONF value to the end of the file:


NETWORKING=YES
HOSTNAME=localhost.localdomain
NOZEROCONF=yes


 More information about zeroconf could be found at: http://en.wikipedia.org/wiki/Zero_configuration_networking

这么说，若是Oracle Linux/Redhat Linux作为Oracle DB Server使用，是不是要强制：把NOZEROCONF=yes添加到/etc/sysconfig/network中？
感觉是要把NOZEROCONF=yes添加到/etc/sysconfig/network中!

但是在RAC 和 Oracle Clusterware 最佳实践和初学者指南 (Linux) (Doc ID 1525820.1)中，并没有NOZEROCONF的描述。
