归档误删除，RMAN备份失败

错误信息如下：

Starting backup at 16-AUG-14

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN> 

 

备份在进行容灾切换时在灾备端产生，没有COPY至生产端，导致备份时2个归档文件找不到，归档备份失败，之后的删除语句无法执行。

对归档进行crosscheck即可，标记为无效。

 

run
{
 allocate channel c1 device type disk maxpiecesize=4096M connect sys/pwd@SYMBOLS2;
 allocate channel c2 device type disk maxpiecesize=4096M connect sys/pwd@SYMBOLS1;
 crosscheck archivelog all;
 release channel c1;
 release channel c2;
}

 

 

再次执行全备及删除策略即可。

 

不建议在备份脚本中增加crosscheck archivelog all;，如果出现归档被误删，则可能无法及时发现归档丢失的问题。
