1.oracle 11G监听配置文件的路径
图形界面下的监听和数据库配置命令：
#netca 监听
#dbaca 数据库创建和配置。
/u01/app/oracle/product/11.2.0/db_1/network/admin
当然oracle的路径不是绝对就和上面的一样，但是oracle在linux下安装配置都会设置环境变量。
cd $ORACLE_HOME or cd $ORACLE_BASE
$ORACLE_HOME下面就可以找到network/admin中的监听配置文件。
[oracle@redhat admin]$ ls
listener1507241PM4645.bak listener.ora tnsnames1507244PM5648.bak
listener1507241PM4920.bak samples tnsnames1507244PM5827.bak
listener1507243PM1207.bak shrept.lst tnsnames.ora
listener1507244PM5648.bak tnsnames1507241PM4920.bak
listener1507244PM5827.bak tnsnames1507243PM1207.bak
ps：listener.ora中的host和tnsname.ora中的host要一致才行，当然做个/etc/hosts
的临时主机名解析也可以，listener.ora中是ip(hostname 也没问题)，而tnsname.ora中是hostname
2.监听启动停止和查看状态的命令。
ps：监听启动是需要时间的。
#lsnrctl stop
#lsnrctl start
#lsnrctl status
ps：如果有多个监听程序名，也可以查看特定的监听名称状态：lsnrctl status/stop/start listener1
[oracle@redhat ~]$ lsnrctl stop
