应客户要求在xx公有云上面安装19c rac,通过各方的努力,最后安装情况如下
1. 两个节点root.sh执行成功,crs启动正常,asm磁盘组访问正常,但是有一个节点asm实例无法启动,一个节点的db实例无法启动

从日志看异常节点的169.254.14.18:32056和169.254.17.231:19443无法使用udp进行通讯,参考:Only One Instance of a RAC Database Can Start at a Time: Second Instance Fails to Start due to “No reconfig messages from other instances” – LMON is terminating the instance (Doc ID 2528588.1),从而使得asm和db实例只能启动一个节点.到目前为止,初步看很可能是公有云的对于169.254网段的某些限制导致.
对于两个节点asm磁盘组mount,crs正常启动.这个是由于使用的是fiex asm技术实现(在asm实例启动正常情况下直接启动本地asm实例,在本地asm实例无法正常启动,通过fiex asm实现磁盘组正常mount)
