环境：contos 6.9搭建Oracle 11.2.0.4

安装oracle软件后，netca创建监听却报下面的错误:

Oracle Net Services Configuration:

问题原因：是由于默认的主机名导致的；

解决办法：修改Linux为非默认主机名，具体操作如下：

[root@localhost ~]$ cat /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=testdb

GATEWAY=192.168.1.254

[root@localhost ~]$ cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

192.168.10.25 testdb

再执行

[root@localhost ~]$hostname testdb

让oracle用户退出重新登录就可以正常启动netca了，至此问题解决。。。

小结：Linux的服务器不要使用默认的主机名，记得要修改主机名。
