如果发现解析有问题，只认第一个 scan ip

默认是 multi on 的（可多个 scan ip ），如果 off 的话会导致该问题

1. 修改 hosts

2. 确认 sacn 信息

srvctl config scan

srvctl status scan

srvctl status scan_listener

[gridßnodel —IS srvctl config scan SCAN name: node-scan, Network . 1/192.168.83.a/255.255.255.uetha SCAN VIP name: scanl, IP: [gridßnodel srvctl status scan SCAN VIP scanl is enabled SCAN VIP scanl is running on node node2 [grid@nodel srvctl status scan_listener SCAN Listener LISTENER_SCANI is enabled SCAN listener LISTENER_SCANI is running on node node2

3. 关闭 scan 监听、 scan 服务

srvctl stop scan_listener

srvctl stop scan

4. 修改 scan 配置

找 srvctl 位置

which srvctl

[gridßnodel —IS which srvctl 'oracle/ grid/crs_l /bin/srvctl

root 执行（ node-scan 是 scan 的别名）

/oracle/grid/crs_1/bin/srvctl modify scan -n node-scan

5. 更新 scan 监听

root 跑

/oracle/grid/crs_1/bin/srvctl modify scan_listener -u

6. 起 scan 监听、 scan 服务

srvctl start scan

srvctl start scan_listener

(grid@nodel —IS srvctl start scan —IS srvctl start scan_listener [grid@nodel

7. 查看 scan 信息

srvctl config scan

[gridOnode1 —IS srvctl config scan SCAN SCAN SCAN SCAN name: node-scan, VIP name: VIP name: VIP name: scanl , scan2, scan3, Network: 1/192.168.83.e/255.255.255.e/ethe 168.83. 190 168.83. 189 168.83. 188 IP: IP: IP: / node-scan/ 192. / node-scan/ 192. / node-scan/ 192.

8. 确认集群信息

有了 3 个 scan 监听和 scan 服务（两个 1 节点上，一个 2 节点上）
