RAC Failover的问题

coolingverse

当RAC其中一个几点宕掉了以后, 另一个节点出现

1. Fri Feb 24 19:38:56 2012
   
2. ospid 26163: network interface with IP address 192.168.1.1 is DOWN
   
3. Fri Feb 24 19:39:56 2012
   
4. ospid 26163: network interface with IP address 192.168.1.1 is now UP
   
5. Fri Feb 24 19:41:56 2012
   
6. ospid 26163: network interface with IP address 192.168.1.1 is DOWN
   
7. Fri Feb 24 20:25:58 2012
   
8. ospid 26163: network interface with IP address 192.168.1.1 is now UP

查看crs日志vip2已经正常的漂移到了rac1上了

1. 2012-02-24 19:28:15.326: [  CRSRES][796287] Attempting to start `ora.portal2.vip` on member `portal1`
   
2. 2012-02-24 19:28:22.173: [  CRSRES][796287] Start of `ora.portal2.vip` on member `portal1` succeeded.

192.168.1.1是心跳线所用的IP, 并且不能自动的failover到正常的节点, 是不是心跳的网卡不断的重启引起的不可以正常的failover呢?

谢谢, 刘大给解释解释.

现象 节点2 频繁的重启  ， 节点1 因为节点2的重启 频繁的发生 reconfiguration

伴随有  ospid 4968: network interface with IP address 192.168.1.1 is now UP  的警告

这可能是由于 192.168.1.1 相关的network interface 不可用导致的  node eviction reboot

建议你 检查 linux 下的dmesg 和 /var/log/messages 确认2个节点的 private network 始终可用。

coolingverse

数据库的版本是10.2.0.4.0
/var/log/messages     和dmesg的输出 这个没法获取到

请给出 DB 版本 ，上传压缩后的alert.log 和 /var/log/messages     和dmesg的输出
