在Oracle 10g环境下搭建数据库监听，可以按照以下步骤进行：

1、配置监听器参数文件

需要创建一个监听器参数文件，在Oracle安装目录下的networkadmin文件夹中，创建一个新的文本文件，例如listener.ora，并编辑该文件，添加以下内容：

“`

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

)

“`

HOST和PORT分别表示监听器的主机名和端口号，如果使用IPC通信，还需要设置KEY参数。

2、启动监听器服务

在命令行中，切换到Oracle安装目录下的bin文件夹，然后执行以下命令启动监听器服务：

“`

lsnrctl start

“`

如果一切正常，将看到类似以下的输出信息：

“`

Service "orcl" has 1 instance(s).

Instance "orcl", status READY, has 1 handler(s) for this service…

The command completed successfully

“`

3、测试监听器服务

可以使用tnsping命令测试监听器服务是否正常工作，在命令行中执行以下命令：

“`

tnsping orcl

“`

如果一切正常，将看到类似以下的输出信息：

“`
