oracle11g 云迁移报错 ORA-01180: can not create datafile 1
1，今天进行oracle云迁移，执行到rman的restore database;的时候报错信息：
RMAN> restore database;
Starting restore at 21-MAR-16
using channel ORA_DISK_1
creating datafile file number=1 name=/data/oracle/powerdes/system01.dbf
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 03/21/2016 20:47:09
ORA-01180: can not create datafile 1
ORA-01110: data file 1: '/data/oracle/powerdes/system01.dbf'
RMAN> exit
2，方案一：看到不能create，查看到/data/oracle/powerdes目录已经有 ，所以移除mv，此方案不能生效
[oracle@yueworldoracle_crm backup]$ mkdir /tmp/oracle/
[oracle@yueworldoracle_crm backup]$ mv /data/oracle/powerdes/*.dbf /tmp/oracle/
3，方案二：重新去原idc库上备份控制文件，再进行恢复，此方案还是不通
去原来的库上，备份控制文件：
RMAN> backup current controlfile;
Starting backup at 21-MAR-16
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=139 device type=DISK
channel ORA_DISK_1: starting full datafile backup set
channel ORA_DISK_1: specifying datafile(s) in backup set
including current control file in backup set
channel ORA_DISK_1: starting piece 1 at 21-MAR-16
channel ORA_DISK_1: finished piece 1 at 21-MAR-16

channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01
Finished backup at 21-MAR-16
RMAN> exit
将控制文件传输到云库上面：
[oracle@wgq__web_3_90 data]$ scp -P5001 /oracle/app/oracle/flash_recovery_area/POWERDES/backupset/2016_03_21/o1_mf_ncnnf_TAG20160321T211047_cgzwprbc_.bkp 2.15.27.6:/oracle/backup/

4，方案三：闪回区有归档，影响了restore，所以删除闪存区的归档日志
搜索归档目录，发现处于闪回区的目录下面：
[root@yueworldoracle_crm soft]# find /data -name archivelog
/data/oracle/app/oracle/flash_recovery_area/POWERDES/archivelog
[root@yueworldoracle_crm soft]# su - oracle
[oracle@yueworldoracle_crm ~]$ cd /data/oracle/app/oracle/flash_recovery_area/POWERDES/archivelog
[oracle@yueworldoracle_crm archivelog]$ ll

210M 2016_03_19
177M 2016_03_20
182M 2016_03_21
将这些归档日志移除到临时目录：
[oracle@yueworldoracle_crm archivelog]$ mkdir /data/backup2/
[oracle@yueworldoracle_crm archivelog]$ mv * /data/backup2/
[oracle@yueworldoracle_crm archivelog]$ ll
[oracle@yueworldoracle_crm archivelog]$ ll
total 0
[oracle@yueworldoracle_crm archivelog]$ pwd
/data/oracle/app/oracle/flash_recovery_area/POWERDES/archivelog
开始再做rman恢复操作，先启动到nomount状态：
[oracle@yueworldoracle_crm archivelog]$ rlwrap sqlplus / as sysdba
