参考：438580.1
备份spfile:
SQL> create pfile='d:\initsid.ora' from spfile;
控制文件备份：
SQL> alter database backup controlfile to '+DG1';
SQL> alter system set control_files='+DG1\ORCL10G\CONTROLFILE\<system generated control file name from diskgroup DG1>' SCOPE=SPFILE;
恢复控制文件到新位置：
$ rman target /
RMAN > shutdown immediate;
RMAN > startup nomount;
RMAN> restore controlfile to '<new_diskgroup i.e +DG1>' from '+DG2\ORCL10G\CONTROLFILE\mycontrol.ctl';
RMAN > alter database mount;
拷贝数据文件到新位置：
RMAN> backup as copy database format '+DG1';
RMAN> switch database to copy;
RMAN> recover database ;
RMAN> alter database open resetlogs;
TEMP文件位置更新：
SQL> alter tablespace TEMP add tempfile '+DG1' SIZE 10M;
SQL> alter database tempfile '+DG2/orcl10g/tempfile/temp.265.626631119' dro
LOGfile文件位置更新：
SQL> alter database add logfile member '+DG1' to group 1;
SQL> alter database add logfile member '+DG1' to group 2;
SQL> alter database add logfile member '+DG1' to group 3;
SQL> alter database add logfile member '+DG1' to group 2;
SQL> alter database add logfile member '+DG1' to group 3;
SQL> alter database drop logfile member 'complete_name';
检查所有文件位置：
SQL> select name from v$controlfile
union
select name from v$datafile
union
select name from v$tempfile
union
select member from v$logfile
union
select filename from v$block_change_tracking
union
select name from v$datafile
union
select name from v$tempfile
union
select member from v$logfile
union
select filename from v$block_change_tracking
