如何在更改主机名后启动 Oracle TNSListener？

Question

跑步时

lsnrctl status

我可以看到它使用的是旧主机名，但我不知道它从哪里提取该值。

我的 Oracle 在 Windows7 x64 上的安装是 11.2.0，如果这有什么不同的话。

当您运行时lsnrctl status，它告诉您的一件事是侦听器参数文件（listener.ora 文件）的位置

如果你打开那个文件，可能会有这样的条目

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

指定主机的位置。更改那里的主机并重新启动侦听器。
