客户的监控反馈有个监听无法连接，登录环境检查发现ora.LISTENER.lsnr的状态为Not All Endpoints Registered，如下
[root@db2 ~]# crsctl status res -t

经常遇到该类问题，有人使用oracle用户启停监听造成的，
[root@db2 ~]# ps -ef |grep LISTENER
root 2259 1936 0 13:58 pts/4 00:00:00 grep LISTENER
oracle 10681 1 0 Nov03 ? 00:20:01 /u01/app/oracle/product/11.2.0/db_1/bin/tnslsnr LISTENER -inherit
grid 32641 1 0 13:55 ? 00:00:00 /u01/app/grid/product/11.2.0/grid_1/bin/tnslsnr LISTENER -inherit
[root@db2 ~]#
处理办法：使用oracle用户把监听关闭 lsnrctl stop
orcl2:/home/oracle@db2> lsnrctl stop
