RMAN-06023

 

1.      执行还原时显示DATAFILE 12即APP01.ORA OFFLINE,没有被还原:

 

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

 

ORA-00289: suggestion : D:\ORACLE_HOME\RDBMS\ARC00006.001

 

ORA-00280: change 32493938 for thread 1 is in sequence #6

 

 

 

 

 

Specify log: { =suggested | filename | AUTO | CANCEL}

 

cancel

 

Media recovery cancelled.

 

SQL> alter database open resetlogs;

 

 

 

Database altered.

 

 

 

SQL>

 

 

 

至此,数据库成功恢复!,现在赶紧做一个数据库备份吧.
