我安装了 Oracle 11gR2,现在我正在尝试从远程系统访问数据库。

我的 listener.ora 仍然是默认的:

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /media/oracle/app/oracle

./lsnrctl services返回:

oracle@ubuntu:/media/oracle/app/oracle/product/11.2.0/dbhome_1/bin$ ./lsnrctl services

LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 05-MAY-2010 05:00:49

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))

         (ADDRESS=(PROTOCOL=tcp)(HOST=ubuntu.localdomain)(PORT=47616))
The command completed successfully

我无法使用端口 1521 获得远程连接,但上面列出的端口 47616 可以工作。我不介意使用与 1521 不同的端口,但问题是该端口在每次重新启动时都会更改。

出了什么问题?

谢谢!

这不是编程问题,可能属于服务器故障。

但是,我会想到以下内容:

localhost 是否在 /etc/hosts 中定义?而且,如果您想从网络访问侦听器,则不应在本地主机上侦听,而应在外部地址上侦听。

端口 1521 可用吗?通过运行 netstat -tlnp 进行验证。
