1.查看监听：lsnrctl status

2.停止监听：lsnrctl stop

3.修改oracle安装目录的下的配置文件listener.ora：一般路径为自己Oracle安装目录+/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

4.查看local_listener

　　su - oracle

　　sqlplus / as sysdba

　　show parameter local_listener

　　alter system set local_listener = "(address = (protocol = tcp)(host = 192.168.1.1)(port = 11521))";

　　show parameter local_listener

　　exit

5.启动监听：lsnrctl start

6.查看状态：netstat -an|grep 11521
