赶快去主库进行备份，然后使用最原始的方式恢复数据库；RMAN备份直接restore、recover的方式，主库编写脚本，进行备份控制文件，参数文件，全库备份；
rman target /

run
{allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup filesperset 3 as compressed backupset database format '/home/oracle/0705/fulldata%d%T%s%p';
backup archivelog all format '/home/oracle/0705/arch%d%T%s%p' delete input;
backup current controlfile format '/home/oracle/0705/ctl%d%T%s_%p';
}

单独备份一下控制文件
backup current controlfile for standby format '/home/oracle/ctl.bak';
将备份集全部scp到备库中
scp 0705/* 18.10.11.12:/home/oracle/0705
scp /home/oracle/ctl.bak 18.10.11.12:/home/oracle/0705

备库启动到no mount阶段，进行restore standby controlfile恢复控制文件

RMAN> restore standby controlfile from '/home/oracle/0705/ctl_DWJRDB_20180705_73_1';

备库启动到mount阶段

RMAN> catalog start with '/home/oracle/0705';

开始restore database操作

RMAN> restore database;

开始rocover database操作

RMAN> recover database;

RMAN> alter database open;

备库应用日志
SQL>alter database recover managed standby database using current logfile disconnect from session;

查看备库信息；
