TNS-03505:Failed to resolve name

上网google了一下,说是环境变量有问题。 看了一下,环境变量确实有点问题。 Oraclepath 是放在中间,,官方要求是将Oraclepath放到最前面。 这里要注意的地方,如果在界面上来修改环境变量,是需要重启电脑的。这样太麻烦了。 直接在dos里修改,就不用重启了,这样也方便很多。

1. 在界面修改

我的电脑->属性->高级->环境变量,找到PATH,把里面的顺序改一下,顺便看一下ORACLE_HOME这个变量,如果没有,就加上去。

这种修改方法需要重新启动电脑。

C:\>DOS窗口修改后,我们可以检查我的电脑”->“属性”->“高级”->“环境变量中设置的 PATH 值,它也自动修改了。不用担心DOS窗口中的修改会影响环境变量的值,DOS窗口中的环境变量只是Windows环境变量的一个副本而已。但是对副本的修改却会引发Windows环境变量的刷新,这就达到了我们不用重启电脑的目的。
