ORA-01153: an incompatible media recovery is active

早上在DG备库上启动MRP进程时，alter database  recover managed standby database using current logfile disconnect from session; 系统报ORA-01153: an incompatible media recovery is active。从字面意思看，有一个不兼容的恢复处于活动状态。

alter database recover managed standby database cancel，取消MRP应用。再重新启动MRP应用，

alter database recover managed standby database cancel;

lter database  recover managed standby database using current logfile disconnect from session; 这时启动日志实时用户没有报错
