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
