重建scan监听命令
（1）查看集群各资源状态
crsctl stat res -t
（2）停止现有scan监听
srvctl stop scan_listener
（3）移除集群中scan监听
srvctl remove scan_listener
（4）添加新的scan监听
srvctl add scan_listener -l LISTENER
（5）查看集群监听是否添加成功
crsctl stat res –t
（6）开启scan监听
srvctl start scan_listener
1、查看集群中监听的状态
[root@vast1 ~]# su - grid
[grid@vast1 ~]$ crsctl stat res -t

3、分别查看三个scan_listener状态，均为关闭
[grid@vast1 ~]$ lsnrctl status listener_scan1

4、移除集群中scan监听 查看集群状态中scan监听已经消失。
[grid@vast1 ~]$ srvctl remove scan_listener
Remove scan listener? (y/[n]) y
[grid@vast1 ~]$ crsctl stat res -t

5.添加scan监听，集群会根据/etc/hosts文件中的scanIP来创建scan监听
[grid@vast1 ~]$ srvctl add scan_listener -l LISTENER
[grid@vast1 ~]$ crsctl stat res -t

6、开启scan监听
[grid@vast1 ~]$ srvctl start scan_listener
[grid@vast1 ~]$ crsctl stat res -t

7分别查看scan监听状态
[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
这里发现listener_scan1没有开启，不必担心，是因为listener_scan1在节点二上，这个可以从集群信息中看到。
[grid@vast1 ~]$ lsnrctl status listener_scan2
LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 24-OCT-2016 08:19:17

这是发现scan_listener中还是没有数据库的信息，不必担心，等一会儿到周期，数据库就会将信息动态推送给scan_listener（大概1分钟左右）。
如果时间太久，还是没有信息则尝试手动推送一下。命令如下
[root@vast1 ~]# su - oracle
[oracle@vast1 ~]$ sqlplus / as sysdba;
