dataguard ORA-16037: user requested cancel of managed recovery operation

今天用脚本检测到主库跟备库未同步，收到邮件如下，立刻登录到备库去查看，发现备库有大量的归档未应用

查询备库日志

tlog
Errors in file /u01/app/oracle/diag/rdbms/xyxdbdg/xyxdb/trace/xyxdb_pr00_13300.trc:
ORA-16037: user requested cancel of managed recovery operation
Recovery interrupted!

查询进程状态mrp

检查发现1319序号日志丢失，其他日志都存在

由于主库下面的归档已经删除，直接在主库里面将1319归档还原．

总结：

出现此错误原因应该是主库rman策略

CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

管理员在配置此策略的时候没有生效

其实出现此错误如果归档过多可以考虑在备库基于scn恢复
