启动oracle数据库时，提示没有监听器 如果，你在控制面板/管理工具/服务中双击打开oracleorahome92tnslistener的服务看到其“可执行文件的路径”一栏为空时的处理方法： 首先运行regedit.exe启动注册表编辑器，在hkey_local_machine/system/controlset002/下的services和currentcontrolset/services下找到oracleorahome92tnslistener项，在右边窗口按右键，新建/字符串，取名imagepath。 双击新见的建，在“数值数据”项输入d:\oracle\ora92\bin\tnslsnr.exe（根据你自己的实际情况进行修改），确定完成。 再次在服务中双击打开oracleorahome92tnslistener的服务看到其“可执行文件的路径”一栏已经显示了其正确的值。这时你可以启动监听了。
