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：

【Vegas原创】用dbms_backup_restore解决RMAN-06026 06023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

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;
/

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：
