对于Oracle 11g RAC 的安装，与Oracle 10g(clusterware)类似，grid 安装完毕后需要执行orainstroot.sh和root.sh，如果是AMD芯片，Oracle说不认识啊，那就要恭喜一下你又多了一次patch的亲密接触，这个错误提示是Failed to create or upgrade OLR。客官，中招了？接着往下看...
1、安装时的环境

3、问题分析
关于这个问题，Meatlink 上[ID 1068212.1]有关于这个问题的描述，同时也说明明了由bug 8670579所引起的，而且还是未公开的，说是
不认识新的AMD芯片，我倒...
一起来看看解决办法吧。
Cause
Unpublished bug 8670579 which relates to the identification of newer AMD chips and therefore only affect platforms
using the newer AMD chips.
