九乡新闻网读书的重要性发展历史:RMAN-06023找不到备份集处理一例--rainnyzhong的博客
来源：百度文库 编辑：九乡新闻网 时间：2024/10/05 21:34:12
RMAN TARGET SYS/SYS@RAINNY CATALOG CATALOG/CATALOG@OEMREP
(1) 还原SPFILE
RMAN>STARTUP FORCE NOMOUNT;
RMAN>RESTORE SPFILE;
(2) 还原CONTROL FILE
RMAN>SHUTDOWN IMMEDIATE;
RMAN>STARTUP NOMOUNT;
RMAN>RESTORE CONTROLFILE;
RMAN>ALTER DATABASE MOUNT;
RMAN>RESTORE DATABASE;
RMAN>RECOVER DATABASE;
这时报:datafile 12 need to be restored!
(3) 试图还原datafile 12
RMAN>restore datafile 12;
报: RMAN-06023: no backup or copy of datafile 12 found to restore
RMAN>list backup of database
在备份列表中datafile 12又明明存在,为什么还会报找不到备份集呢?也许是我有做过表空间时间点恢复的原因.
2. 在此只好用dbms_backup_restore包来还原数据文件12:APP01.ORA
sqlplus /nolog
SQL>conn sys/sys@rainny as sysdba;
SQL>shutdown immediate;
SQL>startup nomount;
开始执行还原数据文件12:
DECLARE
devtype varchar2(256);
done boolean;
BEGIN
devtype:=sys.dbms_backup_restore.deviceAllocate (type=>'',ident=>'I1');
sys.dbms_backup_restore.restoreSetDatafile;
sys.dbms_backup_restore.restoreDatafileTo(dfnumber=>12,toname=>'D:\ORACLE_HOME\ORADATA\RAINNY\APP01.ORA');
sys.dbms_backup_restore.restoreBackupPiece(done=>done,handle=>'F:\zq_orabackup\RAINNY_20061222_0OI5J6KU_1_1.BAK', params=>null);
sys.dbms_backup_restore.deviceDeallocate;
END;
/
数据文件12被还原,mount数据库,我们现在要恢复数据库:
SQL> alter database mount;
Database altered.
SQL> recover database using backup controlfile until cancel;
ORA-00279: change 32493938 generated at 12/22/2006 15:32:30 needed for thread 1

Media recovery cancelled.
SQL> alter database open resetlogs;
