PS：遗憾的是恢复失败，google了很久，发现只能通过sys.dbms_backup_restore.restoreDatafileTo的方式来做不完全一致恢复。
?
2，使用sys.dbms_backup_restore.restoreDatafileTo来做不完全一致数据恢复
?
2.1，先做restoreDatafileTo的数据抽取工作，也就是将数据文件从备份集中抽取出来，记得数据文件路径要与线上保持一致。
执行命令如下：
SQL> DECLARE devtype varchar2(256); doneboolean; BEGIN devtype:=sys.dbms_backup_restore.deviceAllocate(type=>'',ident=>'t1'); sys.dbms_backup_restore.restoreSetDatafile; sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>01,toname=>'/home/oradata/powerdes/system01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>02,toname=>'/home/oradata/powerdes/sysaux01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>03,toname=>'/home/oradata/powerdes/undotbs01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>04,toname=>'/home/oradata/powerdes/users01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>05,toname=>'/home/oradata/powerdes/powerdesk01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>06,toname=>'/home/oradata/powerdes/plas01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>07,toname=>'/home/oradata/powerdes/pl01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>08,toname=>'/home/oradata/powerdes/help01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>09,toname=>'/home/oradata/powerdes/adobelc01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>10,toname=>'/home/oradata/powerdes/sms01.dbf'); sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>11,toname=>'/home/oradata/powerdes/plcrm01.dbf'); sys.dbms_backup_restore.restoreBackupPiece(done=>done,handle=>'/pddata2/oracle/backup/data/2015-03-30/full_POWERDES_20150330_3395.bak',params=>null); sys.dbms_backup_restore.deviceDeallocate; END; /
PS：handle是执行备份的bak文件；最后的/不能少。

执行过程需要一段时间，慢慢等待，后台的alert日志会依次有如下信息显示出来提示抽取成功：
