一、描述
单实例ADG数据库，备库system01.dbf文件损坏，需要重新恢复数据文件，保证主库库数据一致。

二、处理过程

1、数据库启动到mount状态
Recovery Manager: Release 11.2.0.4.0 - Production on Thu Dec 12 20:42:35 2019

connected to target database (not started)

RMAN> startup mount;

Oracle instance started
database mounted

Total System Global Area 3089920000 bytes

Fixed Size 2257232 bytes
Variable Size 654315184 bytes
Database Buffers 2415919104 bytes
Redo Buffers 17428480 bytes

2、使用RMAN恢复
$rman target sys/xxxx@devdb auxiliary sys/xxx@devdbdg

Recovery Manager: Release 11.2.0.4.0 - Production on Thu Dec 12 20:43:53 2019

connected to target database: DEVDB (DBID=931475173)
connected to auxiliary database: DEVDB (DBID=931475173, not open)

RMAN> run {
allocate channel d1 type disk ;
allocate channel d2 type disk ;
backup as copy reuse
datafile 1 auxiliary format '/oradata/devdbdg/system01.dbf';
}2> 3> 4> 5> 6>

using target database control file instead of recovery catalog
allocated channel: d1
channel d1: SID=1145 device type=DISK

allocated channel: d2
channel d2: SID=1715 device type=DISK

Starting backup at 12-DEC-2019 20:45:23
channel d1: starting datafile copy
input datafile file number=00001 name=/oradata/devdb/system01.dbf

output file name=/oradata/devdbdg/system01.dbf tag=TAG20191212T204523
channel d1: datafile copy complete, elapsed time: 00:00:15
Finished backup at 12-DEC-2019 20:45:38
