抱歉上文编辑不下,才续写此文
可为什么该目录会丢失呢,原因是因为ORACLE的BUG,且看故障元凶:Bug 4431215的定位过程,看如下三个日志,节点1在归档到8211发生错误,节点2在归档到6852发生错误,而1点钟有个RMAN定时JOB发起2级备份,备份后会删除归档日志,从RMAN日志可以看出,最大的备份号分别为8210和6851,这和节点ALERT日志是完全一致的,可见在RMAN备份后归档便发生了错误,而RMAN备份后的瞬间,归档目录是空的,这难免让人想到ORACLE在ASM环境下的一个BUG:“在ASM上建立的目录名称和SID前缀相同,则这个目录下的所有目录一旦为空,就会被ASM实例自动删除,不管这个目录是ASM自动建立,还是用户手工建立的。”。登陆ORACLE官方站点确认有该BUG:“Bug 4431215 - "backup archivelog all delete input" from RMAN removes ASM directory [ID 4431215.8]”,至此故障调查完成。

事实上只要处理时间稍微充裕那么一点,我们不难发现更简便的方法,通过ASMCMD直接创建丢失的archivelog目录就可以了。
我们最后的处理:
通过ASMCDM在+DATA下新建了archivelog目录,然后在此目录下新建子目录,为什么不建立文件(因为笔者没有找到10G ASM下建文件的命令,如果有人知道,烦请指导,谢谢)
