Oracle tns监听器错误
我刚刚安装了 Oracle 10g 当我尝试连接到 oracle db 时出现错误：
无法启动 OracleOraHome92TNSListener
当我进入服务并尝试启动它时， ，它说该文件不存在。服务文件是 C:\oracle\ora92\BIN\TNSLSNR （TNSLSNR 是一个文件而不是目录）
C:\oracle\ora92\BIN\TNSLSNR 在我的机器上根本不存在。你知道如何得到它吗？
无法在本地计算机上启动 Oracle Ora92 Listener 服务。错误 2：系统找不到指定的文件
I've just installed Oracle 10g When I try to connect to oracle db i get an error:

Could not start the Oracle Ora92 Listener service on Local Computer.Error 2: The system cannot find the file specified

这是我看到的几个问题。你说你安装了10g但错误是9.2错误。可能是您的计算机上已有 Oracle 9i，但配置错误或卸载，从而导致了该错误。
您需要检查磁盘并找到安装 Oracle 10g 的 ORACLE_HOME（目录）。一旦发现可以调整 PATH 以及 ORACLE_HOME 和 TNS_ADMIN 环境变量以指向正确的位置。这应该允许您启动数据库和侦听器。
如果您需要安装 10g 的 Oracle 客户端，那么下面的信息也会很有帮助。
Oracle客户端可以单独安装。只需访问此地址，下载客户端并将其解压缩到子目录中，然后通过从该目录运行 setup.exe 来运行 Oracle Universal Installer。

Here's a couple of issues I see. You say you installed 10g but the error is a 9.2 error. It could be that your computer already had an Oracle 9i on it that was mis-configured or uninstalled and that is leading to the error.
You need to check your disk and find the ORACLE_HOME (directory) where Oracle 10g was installed. Once you find that you can adjust the PATH and ORACLE_HOME and TNS_ADMIN environment variables to point to the right place. This should allow you to start the database and the listener.
If you need to install the Oracle Client for 10g then this information below will be helpful as well.
The Oracle client can be installed separately. Just go to this address, download the client and unzip it into a subdirectory and then run the Oracle Universal Installer by running setup.exe from the directory.
