症状
RMAN 备份失败显示1153 (ORA-01153 / ORA-1153)
MRP0: Background Media Recovery terminated with error 1153
ORA-01153: an incompatible media recovery is active

MRP0: Background Media Recovery terminated with error 1153
原因
虽然在为备用数据库运行托管的恢复时可以创建RMAN备份，但客户使用keep选项时可能对于RMAN备份不进行同样操作。在11g中当指定了keep子句时，RMAN 尝试创建一个一致性备份，但这是不可能的，因为在备用数据库上在运行媒体恢复。请参阅本文获取有关使用keep选项备份的一致性的一些有用的背景资料：

解决方案
要在11g中在备用数据库上使用keep子句创建备份，你必须停止托管恢复并在只读模式下按照以下文档打开数据库：
<Note 1274127.1> RMAN-6764 "standby database must be open read only before creating a KEEP backup"
