我昨天在OEL5上安装了Oracle 11g，并且能够访问EM（https://localhost.localdomain:1158/em）。但是，当尝试连接时，它无法连接。
我可以连接到db vis sqlplus并验证Listener和dbconsole是否正在运行。我多次关闭并启动了DB，dbaconsole和Listerner，但仍然无法访问EM（https://localhost.localdomain:1158/em）。此外，在重新启动机器后完成此操作但仍然存在同样的问题。
我检查了以下有警告和错误的日志文件：

我花了最近两天在线查看，但未能解决此问题。它可能是localho的一个问题，非常感谢任何帮助/建议，如果你能提供易于遵循的说明，因为我是Linux和Oracle 11g的新手。
非常感谢提前.st.localdomain，但我不确定如何检查或更新。
