12c rac中,当脑裂发生时,哪个节点会幸存下来?

适用于:

Oracle Database - Enterprise Edition - Version 12.1.0.2 and later

Information in this document applies to any platform.

目的:

理解 从12.1.0.2开始,当脑裂发生时,哪个节点会幸存下来?

细节:

在11.2或者之前更老的版本中,当脑裂发生时, the lowest number node 会幸存下来。随着 node weight的引入,这个规则在12.1.0.2中有了改变。

从12.1.0.2开始,在脑裂发生时,higher weight的node将会幸存下来。
