如何从数据库本机系统命令行模式，进入到oracle数据库超级用户操作界面？
1、需要配置安装VNC，然后通过VNC连接
2、安装和配置VNC
① 安装vnc
# yum install -y tigervnc-server tigervnc-server-module libXfont pixman xterm xorg-x11-twm 安装vnc及字体库
# chkconfig vncserver on 设置开机自动启动
②VNC配置
修改 /etc/sysconfig/vncservers 文件，添加以下内容
# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the lines below to start a VNC server on display :2
# as my 'myusername' (adjust this to your own). You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted! For a secure way of using VNC, see this URL:
# http://kbase.redhat.com/faq/docs/DOC-7028
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel. See the "-via" option in the
# `man vncviewer' manual page.
# VNCSERVERS="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"
VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1024x768 -nolisten tcp -depth 24"
# -alwaysshared代表允许多用户同时登录 -depth代为色深，参数有8,16,24,32
#红色为新增内容
③ 设置VNC密码
# vncpasswd
Password:
Verify:
连续两次输入同样的密码
设置的密码保存在 /root/.vnc/passwd
④ 修改防火墙配置，修改/etc/sysconfig/iptables
# vi /etc/sysconfig/iptables #编辑，添加以下代码，开启5901、5902端口
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5902 -j ACCEPT
:wq! 保存，退出
service iptables restart # 重启
⑤使用VNC连接centos主机
直接打开VNC，输入IP地址，冒号后面的1代表桌面号，这个要根据你的配置文件定义的桌面号
3、通过vnc登陆后，切换到oracle用户下面，即可进入到oracle的图形配置数据库界面
