环境：
源环境：系统linux-32 oracle:10.2.0.4
目标环境：系统linux-64 oracle:10.2.0.4
准备工作：copy controlfile,spfile备份集。全库备份集。archivelog备份集。
一：restore spfile
使用rman进入其他instance，才可以恢复出spfile
rman> restore spfile to '/u01/micsprod.spfile' from '/u01/micsprodbak/2012_09_06/o1_mf_s_793317938_84kcflvf_.bkp';
根据恢复的spfile，用linux下strings命令打开，，复制到vi下，把controlfile注释掉，编辑成pfile。
sql> startup nomount pfile='/u01/micsprod.pfile';
sql> create spfile from pfile='/u01/micsprod.pfile';
sql> shutdown immediate
sql> startup nomount
二：restore controlfile
[oracle@micsgmm ~]$ rman target /
rman> restore controlfile from '/u01/micsprodbak/2012_09_06/o1_mf_s_793317938_84kcflvf_.bkp';
sql> alter database mount;
sql> show parameter control
name type value
------------------------------------ ----------- ------------------------------
control_file_record_keep_time integer 7
control_files string /u01/app/oracle/oradata/micspr
od/controlfile/o1_mf_85lf9xxp_
.ctl, /u01/app/oracle/flash_re
covery_area/micsprod/controlfi
le/o1_mf_85lf9yjz_.ctl
三：restore datafiles
由于备份集和目标路劲不同，所以要注册备份集和指定恢复后的路劲
rman> catalog start with '/u01/micsprodbak/2012_09_06_1/o1_mf_nnnd0_level0_060912_84k09py2_.bkp'; (注册备份集)
（指定恢复后的路劲）
