由于监听程序原来是使用的是端口1532.现在修改成1521,结果不能启动说监听已经启动了.于是停止监听报错 TNS-01190: The user is not authorized to execute the requested listener command [Oracle@linuxidc admin]$ lsnrctl startLSNRCTL for Linux: Version 11.2.0.1.0 - Production on 03-JUL-2014 11:23:07Copyright （c） 1991, 2009, Oracle.

其中:Security ON: Local OS Authentication 此条提示信息表明监听处于Local OS Authentication认证模式.Oracle 10g版本以及之后的版本中推出了监听的本地操作系统认证安全特性.若监听程序是在当前用户下启动的，则当前用户具有管理监听的所有权利，其他用户对监听的管理将受到限制
因为数据库是11.2.0.1而且使用了oracle restart特性且用户为grid.注册了listener服务且只对默认端口1521有效.之前是1532所以oracle restart不会自动重启监听.由于将端口修改成了1521所以oracle restart自动重启了listener [grid@linuxidc ~]$ srvctl status listener Listener LISTENER is enabled Listener LISTENER is running on node（s）: linuxidc
