oracleRAC无备份情况恢复ocr和olr
最大的悲剧莫过于数据库坏了备份没了。让我想起了前几年流行的一句话：最大的悲剧是人活着，钱没了。总之备份重于一切。 情景介绍： 在11G中ocr的asm磁盘组被用户不小心删了且所有备份都误删，olr呢也损坏了。至此悲剧重演。 恢复过程：(其实就是使用root.
最大的悲剧莫过于数据库坏了备份没了。让我想起了前几年流行的一句话：“最大的悲剧是人活着，钱没了”。总之备份重于一切。
情景介绍：
在11G中ocr的asm磁盘组被用户不小心删了且所有备份都误删，olr呢也损坏了。至此悲剧重演。
恢复过程：(其实就是使用root.sh重建ocr的过程，重建之后可能需要重新注册相关资源如listener or database 实例等!)
1、清空所有节点cluster配置信息：(11G中存在rootcrs.sh脚本，该脚本默认存在于$GRID_HOME/crs/install)。
注，该脚本需要在root下执行，否则会有错误提示
