Question

我最近在CentOS 7上安装了Oracle 11G XE。出于某种原因，监听器在启动后停止工作。我正在使用用于安装数据库实例的用户登录服务器。要运行lsnrctl命令，我需要更改为名为oracle的用户，并在每次更改为此用户时使用命令. ./dbenv.sh加载环境变量。

这是我执行lsnrctl start时的结果：

当我在几秒钟后执行命令lsnrctl status时，显示了什么：

我的listener.ora文件包含：

谢谢大家，我们解决了Windows问题，解决方案是更新Oracle驱动程序，现在一切正常。

为什么Oracle 11g XE监听器停止工作？
