$ ./runInstaller
********************************************************************************
Your platform requires the root user to perform certain pre-installation
OS preparation. The root user should run the shell script 'rootpre.sh' before
you proceed with Oracle installation. rootpre.sh can be found at the top level
of the CD or the stage area.
Answer 'y' if root has run 'rootpre.sh' so you can proceed with Oracle
installation.
Answer 'n' to abort installation and then ask root to run 'rootpre.sh'.

解决方法：
步骤:
① root用户下export DISPLAY= xx.xx.xx.xx:0.0 其中xx.xx.xx.xx为我本地电脑的IP
② vi /etc/ssh/sshd_config
找到#X11Forwarding no 这一行，将其改为 X11Forwarding yes (前面的#要去掉)
③重新启动ssh:
stopsrc -s sshd
startsrc -s sshd
④ 然后断开xshell重新登录系统（任意用户），就可以调出图像界面了。
2、打补丁时，报如下错误。
