原 scan ip 只有一个，现在增加两个 scan ip

1、编辑两个节点的/etc/hosts 文件

[root@rac12c01 ~]# vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

#Public-IP

192.168.10.10 rac12c01

192.168.10.11 rac12c02

#Private-IP

10.10.20.10 rac12c01-priv

10.10.20.11 rac12c02-priv

#Virtual-IP

192.168.10.12 rac12c01-vip

192.168.10.13 rac12c02-vip

#Scan-IP

192.168.10.14 scan-rac

##add two scan

192.168.10.15 scan-rac

192.168.10.16 scan-rac

2、查看确认当前 scan 配置

[grid@rac12c01 ~]$ srvctl config scan

SCAN name: scan-rac, Network: 1

Subnet IPv4: 192.168.10.0/255.255.255.0/ens33, static

Subnet IPv6:

SCAN 1 IPv4 VIP: 192.168.10.14

SCAN VIP is enabled.

SCAN VIP is individually enabled on nodes:

SCAN VIP is individually disabled on nodes:

[grid@rac12c01 ~]$ srvctl status scan

SCAN VIP scan1 is enabled

SCAN VIP scan1 is running on node rac12c01

[grid@rac12c01 ~]$ srvctl status scan_listener

SCAN Listener LISTENER_SCAN1 is enabled

SCAN listener LISTENER_SCAN1 is running on node rac12c01

3、停止 Scan 监听和 scan 服务

[grid@rac12c01 ~]$ srvctl stop scan_listener

[grid@rac12c01 ~]$ srvctl stop scan

[grid@rac12c01 ~]$

4、修改 scan 配置

[grid@rac12c01 ~]$ which srvctl

/u01/app/12.2.0/grid/bin/srvctl

[grid@rac12c01 ~]$ exit

logout

[root@rac12c01 ~]# /u01/app/12.2.0/grid/bin/srvctl modify scan -n scan-rac

[root@rac12c01 ~]#

5、更新 scan listener

[root@rac12c01 ~]# /u01/app/12.2.0/grid/bin/srvctl modify scan_listener -u

6、确认 scan 是否新增完成，确认状态

[root@rac12c01 ~]# su - grid
