首先把Oracle备份文件传到目标端，解压，如下所示是每天的备份，其中20190816是0级别的差异增量备份
，其余的都是1级的差异增量备份。
[oracle@beijing-fuli-Hadoop-03 /data/backup/oracle]$ ll
total 0
drwxr-xr-x 2 oracle oinstall 332 Aug 18 18:39 20190816
drwxr-xr-x 2 oracle oinstall 298 Aug 18 18:41 20190817
drwxr-xr-x 2 oracle oinstall 298 Aug 18 18:44 20190818
1.恢复参数文件（参数文件会在自动备份控制文件的时候进行备份）
RMAN>restore spfile from '/data/backup/oracle/20190818/db2_lev1_c-2174667026-20190818-1a';
然后创建成pfile,进行相应的修改，
create pfile from spfile;
2.恢复控制文件（选择最后一次备份的控制文件即可）
RMAN> restore controlfile from '/data/backup/oracle/20190818/controlfile20190818184413.bak';
Starting restore at 18-AUG-19
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=129 device type=DISK
channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:01
output file name=/data/u01/app/oracle/oradata/db2/control01.ctl
output file name=/data/u01/app/oracle/fast_recovery_area/db2/control02.ctl
Finished restore at 18-AUG-19
3.恢复数据文件并借助归档日志实现数据一致性
3.1告诉rman备份文件在哪里：
RMAN> catalog start with '/data/backup/oracle';
3.2具体恢复，基于时间的恢复，选择一个比较大的时间，就是肯定在备份时间之后的时间！
run {
set until time "to_date('2019-08-28 20:30:13','yyyy-mm-dd hh24:mi:ss')";
restore database;
recover database;
}
3.3打开数据库：
SQL> alter database open resetlogs;
Database altered.
如果你还有更多的 归档日志，可以把日志传输到目的端，然后再进行前面的步骤三，至于到底需要传那几个归档，需要你来判断，就是说只要包含最近一次备份完成后的那个点（scn)即可，然后都是oracle自动去识别哪些是需要应用的archive log，不需要你认为的指定，所以原则是竟可能多传输archive,千万别少传输！
首先在完成最后一次增量备份后，再主库insert一条数据，
SQL> insert into liuwenhe.test values (1010101);
SQL>commit;
SQL> alter system ARCHIVE LOG CURRENT;
然后把最近的archive log传给目的端，
[oracle@beijing-fuli-hadoop-02 archive]$ scp 1_32* oracle@10.9.21.115:/data/backup/oracle
The authenticity of host '10.9.21.115 (10.9.21.115)' can't be established.
