system数据文件520块损坏修复--bbed

原创 Oracle 作者：dbSeeSee 时间：2016-06-28 00:08:25 0 删除 编辑
关于这个数据块就不做多的介绍，网上有很多资料


  1. SQL> select header_file,header_block from dba_segments where segment_name='BOOTSTRAP$';
  2.  
  3. HEADER_FILE HEADER_BLOCK
  4. ----------- ------------
  5.           1 520
下面试验几种段头块被破坏，恢复的情况
1、使用离线备份
2、复制同位置好的数据块
3、修改为原来的值


1、使用离线备份

  1. [oracle@kvm61 ~]$ cp /oracle/oradata/sdk/system01.dbf /oracle/oradata/sdk/system01.dbf.2
同时加入到bbed配置中

  1. [oracle@kvm61 ~]$ vi bbed.conf
  2. 1 /oracle/oradata/sdk/system01.dbf 723517440
  3. 2 /oracle/oradata/sdk/sysaux01.dbf 639631360
  4. 3 /oracle/oradata/sdk/undotbs01.dbf 204472320
  5. 4 /oracle/oradata/sdk/users01.dbf 595066880
  6. 5 /oracle/oradata/sdk/example01.dbf 108134400
  7. 6 /oracle/scripts/sql/TBS_A.DBF 25165824
  8. 7 /oracle/oradata/sdk/users01.dbf.2 595066880
  9. 8 /oracle/oradata/sdk/system01.dbf.2 723517440

  1. [root@kvm61 ~]# su - oracle
