Oracle XE没有绑定IP4端口1521

Question

我在Ubuntu 12.4中安装了Oracle 11g XE，并且在使用TCP端口绑定Oracle时遇到了困难。 IP6绑定似乎很好但不是IP4（tcp 0.0.0.0:1521）。

这是oracle-xe状态：

和监听器配置：

root@pearBox:~# cat /u01/app/oracle/product/11.2.0/xe/network/admin/listener.ora
# listener.ora Network Configuration File:

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/xe)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
      (ADDRESS = (PROTOCOL = TCP)(HOST = pearBox)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

我将主机名更改为“HOST = 127.0.0.1”，它在localhost上绑定，但我无法从网络访问Oracle实例！

如果您能帮助解决此问题，我将不胜感激。

Answer 1

刚发现这篇文章，我遇到了同样的问题。 这是在安装后更改我的主机名的结果。 我能够通过更新两者中的主机名来纠正这种情况：

/u01/app/oracle/product/11.2.0/xe/network/admin/tnsnames.ora

和

/u01/app/oracle/product/11.2.0/xe/network/admin/listener.ora

Answer 2

我建议看看防火墙规则 - > https://help.ubuntu.com/12.04/serverguide/firewall.html

Answer 3

更改主机名对我有用，因为我通过检查发现不匹配：

1. uname -a
2. 监听器日志：log.xml
3. / etc / hosts文件

我在域中添加了完整的主机名

感谢您的帮助，因为我在获得此参考之前已经搜索了一周的互联网帖子。
