启动监听程序报错：

说明：在rhel5.8上安装完成oracle11g数据库后，使用netca创建完监听，启动监听时报错。还未使用dbca创建实例。

[oracle@rusky-oracle11g ~]$ lsnrctl start

TNS-12560: TNS:protocol adapter error
TNS-00507: Connection closed

处理方法：修改/etc/hosts文件如下

[root@rusky-oracle11g ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
#127.0.0.1 rusky-oracle11g.com rusky-oracle11g 把此行注释，添加第二行如下，否则启动监听程序时报错。
127.0.0.1    localhost.domain    localhost 
192.168.1.203 rusky-oracle11g.com rusky-oracle11g

/etc/resolve.con文件默认如下，未做修改：

[oracle@rusky-oracle11g ~]$ cat /etc/resolv.conf 
search com

再次启动监听正常：

[oracle@rusky-oracle11g ~]$ lsnrctl start
