mkdir -p /u01/app/oracle/oradata/hk

mkdir -p /u01/app/oracle/fast_recovery_area/hk

二、设置init和sid

echo 'db_name=hk' > $ORACLE_HOME/dbs/inithk.ora

more $ORACLE_HOME/dbs/inithk.ora

export ORACLE_SID=hk

rman target /

set dbid 3515046639 --原始数据库dbid

三、开始恢复

startup nomount; --启动到nomount

-----恢复spfile文件

restore spfile from '/u01/app/oracle/oradata/hk/hk_spfile_81t2a2gm_1_1.bak';

startup nomount force;-----重启实例到nomount状态

查看spfile文件中控制文件路径，并创建或者如下

restore controlfile from '/u01/app/oracle/oradata/hk/hk_Controlfile_c-3278571708-20180506-01';

ORA-19870: error while restoring backup piece /u01/app/oracle/oradata/hk/hk_Controlfile_c-3278571708-20180506-01

ORA-19504: failed to create file "/oradata/hk/control01.ctl"

ORA-27040: file create error, unable to create file

Linux-x86_64 Error: 2: No such file or directory

mkdir -p /oradata/hk

restore controlfile from '/u01/app/oracle/oradata/hk/hk_Controlfile_c-3278571708-20180506-01';

alter database mount；启动实例到mount状态

restore database; //还原数据文件

channel ORA_DISK_1: ORA-19870: error while restoring backup piece /backup/database/hk_full_6mt1jcvt_1_1

ORA-19505: failed to identify file "/backup/database/hk_full_6mt1jcvt_1_1"

ORA-27037: unable to obtain file status

-------检查/backup/database权限和路径，

restore database;

recover database;

archived log thread=1 sequence=1735

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

recover database until scn 34275591;
