我已经在我的Linux Mint 17.3系统上安装了Oracle database Express Edition 11g Release 2 for Linux x64。安装过程成功。我能够使用sqlplus连接到数据库，创建新用户，执行命令等。在安装期间配置数据库时，我使用了默认端口，即8080和1521。但我无法从我的系统连接到APEX url，即localhost:8080/APEX/f？p=4950。在过去的几个小时里，我一直在寻找解决方案，但在任何地方都找不到

lsnrctl命令的输出如下：

SQL> connect username/password@XE
ERROR:

descriptor

但通常从终端，如果我使用

sqlplus用户名/密码连接，我会成功连接。
我想我必须让XE
和XEXDB
服务运行，但到目前为止我还不能。这方面的任何帮助都将非常有用。提前谢谢。
经过几个小时的“谷歌搜索”和一些“狂饮”，我终于可以解决我的问题了。以下是我为解决我的问题所做的：
alter system set local_listener='（地址=（协议=TCP）（主机=IAMARISH15-HP-15-Notebook-PC）（端口=1521））'范围=两者

步骤#1解决了XE和XEXDB服务未显示的问题，之后当我运行lsnrctl status
时，XE和XEXDB服务都显示，我可以使用用户名使用命令行SQL工具登录/password@XE
命令。但APEX web界面仍然不可用
然后我更新了tnsnames.ora和listener.ora文件，使其包含XEXDB的条目和Presentation=HTTP行的DESCRIPTION条目

之后，我使用以下命令重新加载它们的值：
/etc/init.d/oracle-xe force-reload

这解决了这个问题，我可以连接到APEX web界面，创建新的工作区、用户等。
经过几个小时的“谷歌搜索”和一些“Bing”，我终于可以解决我的问题了。以下是我为解决我的问题所做的：
alter system set local_listener='（地址=（协议=TCP）（主机=IAMARISH15-HP-15-Notebook-PC）（端口=1521））'范围=两者

DEFAULT_SERVICE_LISTENER = (XE)

之后，我使用以下命令重新加载它们的值：
/etc/init.d/oracle-xe force-reload

这解决了问题，我可以连接到APEX web界面并创建新的工作区、用户等。
请看一看：我认为这不适用于我的情况。在我的例子中，没有ip发生更改，而且，lsnrctl status
不返回任何错误/失败消息。但我觉得是由于缺少（DESCRIPTION=（ADDRESS=（PROTOCOL=tcp）（HOST=127.0.0.1）（PORT=8080））（Presentation=HTTP）（Session=RAW））
行与此XE
服务未运行有关，导致apex web界面不可用。但我不知道如何修复它，我不想为了修复apex而把一切都搞糟。请看一看：我认为这不适用于我的情况。在我的例子中，没有ip发生更改，而且，lsnrctl status
