生产一套Oracle 11.2.0.4 的 RAC DG数据库，由于心跳网络的调整需要，原本能正常运行的，发现网络调整后，集群服务启动不正常。启动过程报错如下：

从上面的具体报错，可以看到ora.cluster_interconnect.haip这个资源启动失败，导致集群启动失败，查看/u01/app/11.2.0/grid/log/sbhis1/agent/ohasd/orarootagent_root//orarootagent_root.log 这个日志，查找ora.cluster_interconnect.haip启动失败原因，从该日志可以看到以下报错：

从上面的关键字报错“PROBE: got conflicting source”，可以从MOS上找到相关的解决方案：
HAIP fails to start if default gateway is configured for VLAN for private network on network switch
Issue: HAIP fails to start if default gateway is configured for VLAN for private network on network switch
orarootagent_root.log shows: PROBE: conflict detected src { 169.254.12.247, }, target { 0.0.0.0,
}
The solution is to remove default gateway setting on network switch for private network (VLAN), refer to Note 1366211.1 for more details.
MOS 1366211.1文档有说明报错原因是该心跳网络所在的VLAN配置了网关，HAIP无法获取169.254.x.x 这个段的IP，也就导致ora.cluster_interconnect.haip启动失败。
1、解决方法一：调整网络
知道了原因，解决起来也就简单了，让网络部把这个RAC的心跳单独弄到一个vlan上，并把该vlan的网关设置去掉，这样调整后，就顺利启动集群。
2、解决方法二：禁用HAIP
上面是一种解决方式，有没有另外的解决方法呢，答案是肯定的，把HAIP这个特性禁用了，是不是就可以了。HAIP这个特性是从11.0.0.2版本开始，Oracle提供的私网的高可用性和负载均衡，需要有多块网卡来做配置。如果你在操作系统层面已经做了网卡绑定配置，如linux bonding ，那其实是可以禁用的。要该如何禁用这个HAIP呢？
（1）禁用HAIP资源
--使用root用户执行以下命令。
--停止所有节点的CRS
/u01/app/11.2.0/grid/bincrsctl stop crs
--依次在每个节点中执行以下命令（节点1执行完毕后再在节点2执行）
# /u01/app/11.2.0/grid/bin/crsctl start crs -excl -nocrs
# /u01/app/11.2.0/grid/bin/crsctl stop res ora.asm -init
# /u01/app/11.2.0/grid/bin/crsctl modify res ora.cluster_interconnect.haip -attr "ENABLED=0" -init
(2)修改ASM资源的依赖关系
```language
--查看当前ASM资源的关联关系：
# /u01/app/11.2.0/grid/bin/crsctl stat res ora.asm -p -init

##可以看到ASM资源和HAIP资源的依赖关系。
--修改ASM的关联关系（所有节点执行）
# /u01/app/11.2.0/grid/bin/crsctl modify resource ora.asm -attr "START_DEPENDENCIES='hard(ora.cssd,ora.ctssd)pullup(ora.cssd,ora.ctssd)weak(ora.drivers.acfs)'" -f -init
# /u01/app/11.2.0/grid/bin/crsctl modify resource ora.asm -attr "STOP_DEPENDENCIES=hard(intermediate:ora.cssd)" -f –init
（3）修改cluster_interconnects参数
--修改ASM实例的cluster_interconnects参数
--grid用户执行，修改具体的私网地址
SQL> alter system set cluster_interconnects='10.10.10.11' scope=spfile sid='+ASM1';
SQL> alter system set cluster_interconnects='10.10.10.12' scope=spfile sid='+ASM2';
--修改DB实例的cluster_interconnects参数
--oracle用户执行，修改具体的私网地址
SQL> alter system set cluster_interconnects='10.10.10.11' scope=spfile sid='sbhis1';
SQL> alter system set cluster_interconnects='10.10.10.12' scope=spfile sid='sbhis2';
(4)重启集群
# /u01/app/11.2.0/grid/bin/crsctl stop crs -f
# /u01/app/11.2.0/grid/bin/crsctl start crs
--重启完，检查HAIP是否禁用
$ crsctl stat res -t -init
若ora.cluster_interconnect.haip为offline则为禁用状态。然后执行如下命令：
ifconfig -a 或ip a |grep 169.254
查看是否还有169.254开头的地址，如果没有了，那么说明已经禁用成功。
