oracle 10g cluster rac vip始终在节点2的问题处理

环境:oracle 10g crs+hp_unix+hacmp
用crs_stat -t 查看资源组状态

ora.rac1.gsd application ONLINE ONLINE rac1
ora.rac1.ons application ONLINE ONLINE rac1
ora.rac1.vip application ONLINE ONLINE rac2
ora.rac2.gsd application ONLINE ONLINE rac2
ora.rac2.ons application ONLINE ONLINE rac2
ora.rac2.vip application OFFLINE OFFLINE rac2
可以看出rac1节点的vip漂在rac2节点上
用crs_relocate ora.rac1.vip -c rac1 也切不回来
用netstat -in 查看ip,发现vip地址全部在节点2上
检查rac1节点crs vip日志
2010-05-14 21:08:20.053: [ RACG][1] [16231][1][ora.rac1.vip]: checkIf: Default gateway is not defined (host=rac1)
Interface lan0 checked failed (host=rac1)
checkIf: Default gateway is not defined (host=rac1)
Interface lan2 checked failed (host=rac1)
Default gateway is not defined
rac1节点网关没定义
马上检查rac1和rac2网关设置

设置成功
停止节点资源
srvctl stop nodeapps -n rac1
srvctl stop nodeapps -n rac2
启动节点资源
srvctl start nodeapps -n rac1
srvctl start nodeapps -n rac2

检查,vip分配在各自节点上
./crs_stat -t
Name Type Target State Host

总结:vip和网关有很大的关系，公网ip一定要设置网关（每个节点）
