说明： 版本：Oracle 11.2.0.4.0 RAC
将 scan ip 由 192.0.0.101 改成 192.0.0.100 如果修改的是VIP地址，可以参考我的另一篇文章《Oracle RAC 修改VIP地址》

停scan
root@cjc-db-06:/oracle/grid/product/11.2/bin#./srvctl stop scan_listener root@cjc-db-06:/oracle/grid/product/11.2/bin#./srvctl stop scan
停止scan_listener后scan ip 自动移除
ip a
修改 /etc/hosts 记录的scan ip地址
vi /etc/hosts # scan # 192.0.0.101 cjc-scan 192.0.0.100 cjc-scan
修改ocr注册信息
