谁说不能多个心跳?
Administering Multiple Cluster Interconnects on UINIX-Based Platforms
In Oracle RAC environments that run on UNIX-based platforms, you can use the CLUSTER_INTERCONN ...
oracle的多个心跳并不提供冗余,只是增加不同节点间通信的through put,其中的一个断掉的话,有些节点会自动重起
看reference http://download.oracle.com/docs/ ... ams025.htm#CHDCAEFG
Note that multiple private addresses provide load balancing, but do not provide failover unless bonded. If you specify multiple addresses in init.ora using CLUSTER_INTERCONNECTS, instead of bonding multiple addresses at the operating system level, then typically availability is reduced, because each network interface card failure will take down that instance. |
