修改RACBDB SCAN 配置步骤如下：
1. 修改racb1/racb2主机/etc/hosts配置文件
删除10.39.229.219 raca-scan
增加 10.39.229.229 racb-scan
2. 修改SCAN，并UPDATE SCAN Listener中的配置
root@racb1:/>srvctl modify scan -n racb-scan
root@racb1:/>srvctl modify scan_listener –u
root@racb1:/>srvctl config scan
SCAN name: racb-scan, Network: 1/10.39.229.0/255.255.255.0/en17
SCAN VIP name: scan1, IP: /racb-scan/10.39.229.229
