fishcat论 RMAN使用crosscheck archivelog all注意
本帖最后由 fishcat 于 2013-1-30 10:20 编辑fishcat论 RMAN使用crosscheck archivelog all注意;
RAC环境当归档目录在本地的情况下，在一个节点crosscheck archivelog all会把另外一个节点的日志验证failed，然后delete expired archivelog all 则会将RMAN中这些日志的信息清除
导致备份的时候不会备份这些日志，却不报错。而实际情况是这些归档是存在的。
RMAN>crosscheck archivelog all;
