---------------------------------

是安装Oracle的时候可以选择的。
legato是一家做备份的厂商，可能为了占领市场和Oracle绑在一起了。

你仔细看看安装Oracle的过程是否有选择LEGATO组件的，不选就是了。
还有安装Oracle的时候最好先安装，最后手动建库，这样成功的机率高。

---------------------------------

这个问题是由于在安装oracle时安装了legato相关备份软件而引起的，这种报错对数据库不会有什么影响。

如果要使系统不产生这些信息，可以找到/etc/rc.d/rc3.d下的对应于legato(nsr)的相应链接，将其disable掉就可以了。

---------------------------------

在LEGATO Single Server Version (LSSV) 安装及卸载指导书中发现 和其他没有安装legato软件的相比：多了 /nsr/目录及/etc/init.d/networker

vi    /etc/init.d/networker  

从语句中可以看出， 需要注釋掉 start 部分的語句 .   才能保證log文件中不會報錯 .

当然或者关闭它的服务也可以达到目的 。

[root@dell-node1 init.d]# ./networker  stop  
[root@dell-node1 init.d]#
[root@dell-node1 init.d]# nsr_shutdown -a
