Xwindow开不起来吧

需要仔细的描述一下，你是在什么操作系统的什么版本上安装哪个版本的Oracle

[Abner]

学习中，研究一下

[宋哥]

和视窗有关，简单的办法是在图形界面直接用root登录，而不是用其他用户登录再转到root

[宋哥]

检查一下环境变量DISPLAY

解决了，感谢各位。一开始我是在root账户下su - oracle的，然后运行./runInstaller报上面的错误。之后我直接以oracle账户登入图形界面之后运行./runInstaller可以进入安装界面了。

有问题可再提哟，我等一会结贴，有价值的都送分。。。。

我说反了，其实这个问题我碰到过，时间长了，记错的了。

[宋哥]

我想原因大概是用root登陆后，图形屏幕已经被root占了，后转的Oracle用户无法使用图形屏幕。
