Red Hat Enterprise Linux 5下有關dmrc文件錯誤的解決辦法

平臺：
Red Hat Enterprise Linux 5
2.6.18-194.el5
​
​故障描述，使用oracle用戶登錄linux時報錯：
User's $HOME/.dmrc file is being ignored. This prevents the defaults session and language from being saved. File should be owned by user and have 644 permissions. User's $HOME directory must be owned by user and not writable by other users.

​​故障原因，用戶錯誤地執行了下面的命令：
chmod -R 775 /home/oracle

​​解決辦法，依次執行下面的命令：
sudo chown oracle /home/oracle/.dmrc
chmod 644 /home/oracle/.dmrc
sudo chown oracle /home/oracle
chmod 755 /home/oracle
