ORA-00245: 控制文件备份失败

但是在备份log中，控制文件已经备份成功，应该是备份完成后的控制文件快照备份失败。MOS中有以下文档ORA-245: In RAC environment from 11.2 onwards Backup Or Snapshot controlfile needs to be in shared location (文档 ID 1472171.1)，其中有一段是

5. In RAC environment, Rman backup fails if snapshot controlfile is not in shared location.

ORA-00245: control file backup operation failed

在RMAN中使用show all发现，snapshot果然只是在单个节点中，

CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/app/11.2.0/db_1/dbs/snapcf_db1.f'; # default

修改到shared disk中。

CONFIGURE SNAPSHOT CONTROLFILE NAME TO '<shared_disk>/snapcf_<DBNAME>.f';
