天萃荷净 运维DBA工作人员反映,在使用RMAN备份Oracle数据库时出现ORA-00245和RMAN-08132错误,分析原因为备份控制文件异常导致

1.rman备份数据库报错ORA-00245和RMAN-08132

ORA-00245: control file backup operation failed

RMAN-08132: WARNING: cannot update recovery area reclaimable file list

RMAN> 

从这里可以看出数据库文件,归档日志,spfile和controlfile都备份完成,后面又出现一个controlfile失败,应该是控制文件快照备份失败。

2.Oracle错误ORA-00245和RMAN-08132原因

RMAN creates a copy of the control file for read consistency, this is the snapshot controlfile. 
Due to the changes made to the controlfile backup mechanism in 11gR2 any instances 
in the cluster may write to the snapshot controlfile. Therefore, 
the snapshot controlfile file needs to be visible to all instances.

The same happens when a backup of the controlfile is created directly from 
sqlplus any instance in the cluster may write to the backup controfile file.

In 11gR2 onwards, the controlfile backup happens without holding the control file enqueue. 
For non-RAC database, this doesn't change anything. 

But, for RAC database, the snapshot controlfile location 
must be in a shared file system that will be accessible from all the nodes.

The snapshot controlfile MUST be  accessible by all nodes of a RAC database. 

大致意思就是rman的snapshot controlfile必须放在共享存储之上。

3.Ora错误ORA-00245和RMAN-08132解决方法

The snapshot controlfile MUST be accessible by all nodes of a RAC database, 
if the snapshot controlfile does not reside in on a shared device this error will raise.

1. Check the snapshot controlfile location:
RMAN> show all;

2. Configure the snapshot controlfile to a shared disk:
RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/snapcf_.f';
