进行测试之前先将数据库做全备：

1、利用dbms_backup_restore恢复控制文件
SQL> DECLARE
2 devtype varchar2(256);
3 done boolean;
4 BEGIN
5 devtype := dbms_backup_restore.DeviceAllocate(type => &,ident => ‘testctl’);
6 dbms_backup_restore.RestoresetdataFile;
7 dbms_backup_restore.RestoreControlFileto(’/app/oracle/oradata/ora9i/control01.ctl’);
8 dbms_backup_restore.RestoreBackupPiece(’/backup/full708756233′,done => done);
9 dbms_backup_restore.RestoresetdataFile;
10 dbms_backup_restore.RestoreControlFileto(’/app/oracle/oradata/ora9i/control02.ctl’);
11 dbms_backup_restore.RestoreBackupPiece(’/backup/full708756233′,done => done);
12 dbms_backup_restore.RestoresetdataFile;
13 dbms_backup_restore.RestoreControlFileto(’/app/oracle/oradata/ora9i/control03.ctl’);

15 dbms_backup_restore.DeviceDeallocate;
16 END;

当然也已可用rman进行控制文件恢复
引用

2、利用dbms_backup_restore恢复数据文件
引用
SQL> DECLARE
2 devtype varchar2(256);
3 done boolean;
4 BEGIN
5 devtype := dbms_backup_restore.DeviceAllocate (type => &,ident => ‘testdatafile’);
6 dbms_backup_restore.RestoreSetDatafile;
7 dbms_backup_restore.RestoreDatafileTo(dfnumber => 1,toname => ‘/app/oracle/oradata/ora9i/system01.dbf’);
8 dbms_backup_restore.RestoreDatafileTo(dfnumber => 2,toname => ‘/app/oracle/oradata/ora9i/undotbs01.dbf’);
9 dbms_backup_restore.RestoreBackupPiece(done => done,handle => ‘/backup/full708756233′, params => null);
10 dbms_backup_restore.DeviceDeallocate;
11 END;
12 /
PL/SQL procedure successfully completed.
3、利用dbms_backup_restore恢复归档日志
引用
SQL> DECLARE
2 devtype varchar2(256);
3 done boolean;
4 BEGIN
5 devtype := dbms_backup_restore.DeviceAllocate (type => &,ident => ‘testarchlog’);
6 dbms_backup_restore.RestoreSetArchivedLog(destination=>’/app/oracle/product/9.0.2/dbs/arch’);
7 dbms_backup_restore.RestoreArchivedLog(thread=>1,sequence=>1);
8 dbms_backup_restore.RestoreArchivedLog(thread=>1,sequence=>2);
9 dbms_backup_restore.RestoreArchivedLog(thread=>1,sequence=>3);
10 dbms_backup_restore.RestoreBackupPiece(done => done,handle => ‘/backup/arch708756383′, params => null);
11 dbms_backup_restore.DeviceDeallocate;
12 END;
