今天遇到OracleOraDb11g_home1TNSListener服务启动不了的问题，百度了各类方法，总算结合出一个靠谱的步骤。spa
1. 配置Oracle的listener.ora文件code
安装路径下\product\11.2.0\dbhome_1\NETWORK\ADMIN目录下，其中listener修改成：blog
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 计算机全名)(PORT = 1521)) ) )
安装路径下\product\11.2.0\dbhome_1\NETWORK\ADMIN目录下，其中tnsnames修改成：cmd
ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 计算机全名)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) )
2. 修改注册表 register( cmd --> regedit)it
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/OracleOraDb11g_home1TNSListener中的ImagePath改成：class
安装路径下\product\11.2.0\dbhome_1\BIN\TNSLSNR.EXE （以前后面的.EXE没有）
3. 配置环境变量变量
ORACLE_HOME：安装路径下\product\11.2.0\dbhome_1
4. 重启OracleServiceORCL服务，再启动OracleOraDb11g_home1TNSListener服务便可运行。百度
