                   1 .系统中设置了DISPLAY环境变量

                      执行：

                               unset DISPLAY

                       然后再执行runInstaller.sh，执行成功

                   2.重新启动系统。以oracle的身份登录系统，然后执行./runInstaller

问题二：linux创建oracle时提示 file etc oratab is not accessible

原因是安装oracle的时候，忘记去执行 一个root.sh文件了，当然了，需要用root用户执行：

原因是安装oracle的时候，忘记去执行 一个root.sh文件了，当然了，需要用root用户执行：
解决办法：
               [root@localhost 10.2.0]#cd /oracle/product/10.2.0/db_1

               [root@localhost 10.2.0]# ./root.sh

              The following environment variables are set as:
               ORACLE_OWNER= oracle
               ORACLE_HOME= /opt/oracle/product/10g

               Enter the full pathname of the local bin directory: [/usr/local/bin]:
              Copying dbhome to /oracle/product/10.2.0/db_1/bin

               ./root.sh: line 155: [: too many arguments
               ./root.sh: line 175: [: too many arguments
              Copying dbhome to Copying dbhome to /oracle/product/10.2.0/db_1/bin ...
              ./root.sh: line 175: [: too many arguments
             Copying oraenv to Copying dbhome to /oracle/product/10.2.0/db_1/bin ...
             ./root.sh: line 175: [: too many arguments
             Copying coraenv to Copying dbhome to /oracle/product/10.2.0/db_1/bin ...

             Creating /etc/oratab file...
             Entries will be added to the /etc/oratab file as needed by
             Database Configuration Assistant when a database is created
             Finished running generic part of root.sh script.
             Now product-specific root actions will be performed.

问题三：centos 6.5中文版 安装ORACLE 11G R2 乱码

解决方法：export LC_ALL=en_US.UTF-8
