ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/app/oracle/oradata/orcl/system01.dbf'复制代码恢复用的是
第一步，根据备份的spfile建立相应的目录，adump,bdump,cdump,udump.
第二步，恢复spfile，restore spfile from '/u01/app/rman_backup/controlfileback/cntrl_%s_%p_%s'; 更改$OARCLE_SID目的数据库的sid，然后用恢复的spfile启动数据库到mount状态。
第三步，恢复controlfile， restore controlfile from '/u01/app/rman_backup/controlfileback/cntrl_%s_%p_%s'; 然后建立controfile中对应的数据文件，联机日志文件所对应的目录。
第四步，像controlfile中注册rman信息。catalog start with '/u01/app/‘；
第五步，取回备份数据。 restore database;
第六步，开始恢复 recover database;
第七步，alter database open resetlogs;
