解决办法：
在hosts文件中的127.0.0.1 后面添加对应的主机名，如：
vi /etc/hosts
127.0.0.1 localhost.localdomain localhost rhel5.6
解决办法：
1. 退出oracle，用root登陆；
2. root命令行下输入：
[root@localhost ~]# xhost local:oracle non-network local connections being added to access control list
屏幕提示
xhost: bad hostname “non-network”
xhost: bad hostname”local”
xhost: bad hostname “connetcions”
xhost: bad hostname “being”
xhost: bad hostname “added”
xhost: bad hostname “access”
xhost: bad hostname “control”
xhost: bad hostname “list”
3. 再试试su oracle
[root@localhost ~]# su – oracle
，
