oracle用户界面登陆

用户要切换到oracle

sqlplus / as sysdba    //sys用户是oracle的最高管理员所以要加上as
help index //查看命令列表，sql中不区分大写小写 show user //查看当前用户
quit //退出sql

创建数据库

[[email protected] ~]$ dbca     //会自动跳转出，如果不弹窗口执行: export DISPLAY=:0.0

如提示：No protocol specified，则输入

xhost local:oracle non-network local connections being added to access control list

敲回车运行后出现：

non-network local connections being added to access control list
xhost: bad hostname "non-network"
xhost: bad hostname "local"
xhost: bad hostname "connections"
xhost: bad hostname "being"
xhost: bad hostname "added"
xhost: bad hostname "to"
xhost: bad hostname "access"
xhost: bad hostname "control"
xhost: bad hostname "list"

此时再 输入 dbca,即可弹出图形界面
