无法使用tns连接到Oracle

Question

我使用的是Oracle 11g R2数据库。我使用Oracle SQL Developer。如果我创建了一个新连接并检查了基本连接类型并填写了我可以连接的字段。如果我选择TNS并在下拉菜单中选择我想要的，它会显示失败E/S异常：网络适配器无法建立连接。

这是tnsnames.ora。我用它连接到2个数据库，dblilly和astrea。我可以正确连接到astrea。侦听器已打开，实例已准备就绪。你看到我错过的东西了吗？你需要更多的信息来帮助我吗？

我可以连接与此设置：

但我不能用这个

在listener.ora中，ENVS参数周围缺少一个结束"和一个结束）。

您的TNSNames文件设置为使用服务，但是在sqldeveloper中，您是通过SID连接的。您还应该更改tnsname以指定SID而不是服务名称。

SID与服务名称
