现象：从备份集还原出来的controlfile，用此进行rman还原时，报以下错误：
RMAN-06026: some targets not found - aborting restore
RMAN-06023: no backup or copy of datafile 3 found to restore
RMAN-06023: no backup or copy of datafile 2 found to restore
RMAN-06023: no backup or copy of datafile 1 found to restore
RMAN-06023: no backup or copy of datafile 3 found to restore
RMAN-06023: no backup or copy of datafile 2 found to restore
RMAN-06023: no backup or copy of datafile 1 found to restore
解决方法：
用dbms_backup_restore package进行恢复。
1，Startup nomount;
2，执行恢复：
DECLARE
devtype varchar2(256);
done boolean;
BEGIN
devtype:=sys.dbms_backup_restore.deviceAllocate (type=>\'\',ident=>\'t1\');
sys.dbms_backup_restore.restoreSetDatafile;
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>01,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\SYSTEM01.DBF\');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>02,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\UNDOTBS01.DBF\');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>03,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\SYSAUX01.DBF\');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>04,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\USERS01.DBF\');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>05,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\EXAMPLE01.DBF\');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>06,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\DRSYS\');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>07,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\INDX\');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>08,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\RBS\');
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>09,toname=>\'E:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\TOOLS\');
sys.dbms_backup_restore.restoreBackupPiece(done=>done,handle=>\'D:\HISDBRman\DF343_1_714024003\', params=>null);
sys.dbms_backup_restore.deviceDeallocate;
END;
/
devtype varchar2(256);
done boolean;
BEGIN

sys.dbms_backup_restore.deviceDeallocate;
END;
/
ps：如果有两到三个备份集，需要分开执行以上的代码，替换
sys.dbms_backup_restore.restoreBackupPiece(done=>done,handle=>\'D:\HISDBRman\DF343_1_714024003\', params=>null);
到另一个备份集。
3，看看control文件在不
如果rman备份集里有，就直接：
RMAN> restore controlfile from \'F:\tmp\DF344_1_714024149\';
如果没有，则：
alter database backup controlfile to trace;
找到trace文件，重建你的control文件
4，执行恢复：
SQL> recover database using backup controlfile until cancel;
5，如果4步骤中出现log问题不让恢复的话，参看：
http://www.cnblogs.com/Vegaslee/archive/2010/03/26/1696698.html 联机日志丢失，recover database until cancel不可以的解决方法
6， open resetlogs，好了。
