重建scan監聽命令
（1）查看集羣各資源狀態
crsctl stat res -t
（2）停止現有scan監聽
srvctl stop scan_listener
（3）移除集羣中scan監聽
srvctl remove scan_listener
（4）添加新的scan監聽
srvctl add scan_listener -l LISTENER
（5）查看集羣監聽是否添加成功
crsctl stat res –t
（6）開啓scan監聽
srvctl start scan_listener
1、查看集羣中監聽的狀態
[root@vast1 ~]# su - grid
[grid@vast1 ~]$ crsctl stat res -t

3、分別查看三個scan_listener狀態，均爲關閉
[grid@vast1 ~]$ lsnrctl status listener_scan1

4、移除集羣中scan監聽 查看集羣狀態中scan監聽已經消失。
[grid@vast1 ~]$ srvctl remove scan_listener
Remove scan listener? (y/[n]) y
[grid@vast1 ~]$ crsctl stat res -t

5.添加scan監聽，集羣會根據/etc/hosts文件中的scanIP來創建scan監聽
[grid@vast1 ~]$ srvctl add scan_listener -l LISTENER
[grid@vast1 ~]$ crsctl stat res -t

[grid@vast1 ~]$ srvctl start scan_listener
[grid@vast1 ~]$ crsctl stat res -t

7分別查看scan監聽狀態
[grid@vast1 ~]$ lsnrctl status listener_scan1
LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 24-OCT-2016 08:19:11
Copyright © 1991, 2011, Oracle. All rights reserved.
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
Linux Error: 2: No such file or directory
這裏發現listener_scan1沒有開啓，不必擔心，是因爲listener_scan1在節點二上，這個可以從集羣信息中看到。
[grid@vast1 ~]$ lsnrctl status listener_scan2
LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 24-OCT-2016 08:19:17

這是發現scan_listener中還是沒有數據庫的信息，不必擔心，等一會兒到週期，數據庫就會將信息動態推送給scan_listener（大概1分鐘左右）。
如果時間太久，還是沒有信息則嘗試手動推送一下。命令如下
[root@vast1 ~]# su - oracle
[oracle@vast1 ~]$ sqlplus / as sysdba;
