进入主题，开始增配scan ip
1、修改rac所有节点的/etc/hosts信息
[grid@db1
~]$ vi etc/hosts
127.0.0.1 localhost
10.138.129.101 db1
10.138.129.102 db2
10.138.129.103 db1-vip
10.138.129.104 db2-vip
192.168.20.1 db1-priv
192.168.20.2 db2-priv
10.138.129.105 scan-ip
10.138.129.106 scan-ip
---------新增的scanIP
10.138.129.107
scan-ip ---------新增的scanIP
2、停止scan 监听，注意先听监听才能停scan
[grid@db1
~]$ srvctl stop scan_listener
[grid@db1
~]$ srvctl stop scan
[grid@db1
~]$srvctl status scan_listener
SCAN Listener
LISTENER_SCAN1 is enabled
SCAN listener
LISTENER_SCAN1 is not running
3、配置scan，注意需要用root权限执行
[root@db1
bin]# pwd
/u01/app/11.2.0/grid/bin
[root@db1 bin]# ./srvctl modify scan -n scan-ip
-----修改scan信息，-n 后面接 hosts中的san ip 网络名
[root@db1 bin]# ./srvctl modify scan_listener -u
------添加scanIP的监听，若不执行该命令，将只有一个listener_scan1监听，执行后将根据scan
ip数自动增加listener_scan2，listener_scan3.
4、启动scan
[grid@db1
~]$ srvctl start scan
[grid@db1 ~]$ srvctl
start scan_listener
[grid@db1
~]$ srvctl status scan
SCAN VIP scan1 is
enabled
SCAN VIP scan1 is running on node
db1
SCAN VIP scan2 is enabled
SCAN VIP scan2 is running on node db2
SCAN VIP scan3 is enabled
SCAN VIP scan3 is running on node db1
[grid@db1
~]$ srvctl config scan
SCAN name: scan-ip,
Network: 1/10.138.129.0/255.255.255.0/eth2
SCAN VIP name: scan1, IP:
/scan-ip/10.138.129.105
SCAN VIP name: scan2,
IP: scan-ip/10.138.129.106
SCAN VIP name:
scan3, IP: scan-ip/10.138.129.107
[grid@db1
~]$ srvctl status scan_listener
SCAN Listener
LISTENER_SCAN1 is enabled
SCAN listener
LISTENER_SCAN1 is running on node db1
SCAN
Listener LISTENER_SCAN2 is enabled
SCAN
listener LISTENER_SCAN2 is running on node db2
SCAN Listener LISTENER_SCAN3 is enabled
SCAN listener LISTENER_SCAN3 is running on node
db1
