如何从备份集中恢复归档日志

这一类的操作是因为丢失了所有的控制文件，而RMAN的备份信息又存储在控制文件之中。

所以只能使用DMBS_BACKUP_RESTORE从备份集中恢复数据文件、归档日志等进行恢复。

本例示范如何恢复归档日志文件，恢复数据文件的例子参考:应对RMAN-06026错误，使用dbms_backup_restore进行恢复

SQL DECLARE

2 devtype varchar2(256);

3 done boolean;

4 BEGIN

5 devtype:=sys.dbms_backup_restore.deviceAllocate(type='',ident='t1');

6 sys.dbms_backup_restore.restoreSetArchivedLog(destination='D:\Oracle\oradata\eygle\archive');

7 sys.dbms_backup_restore.restoreArchivedLog(thread=1,sequence=6);

8 sys.dbms_backup_restore.restoreBackupPiece(done=done,handle='D:\oracle\oradata\eygle\bak\ARCH_EYGLE_20050702_7',params=null);

9 sys.dbms_backup_restore.deviceDeallocate;

10END;

执行不完全恢复以后，resetlogs打开数据库:
