SYS@orcl11galter database datafile 6 online;alter database datafile 6 online*ERROR at line 1:ORA-01113: file 6 needs media recoveryORA-01110: data file 6: /opt/oracle/oradata/orcl11g/zbdba01.dbf 有时候我们数据文件offline之后，再online需要

SYS@orcl11g>alter database datafile 6 online;
alter database datafile 6 online
*
ERROR at line 1:
ORA-01113: file 6 needs media recovery
ORA-01110: data file 6: '/opt/oracle/oradata/orcl11g/zbdba01.dbf'

有时候我们数据文件offline之后，再online需要介质恢复

SYS@orcl11g>select file#,name,status from v$datafile;
 FILE# NAME        STATUS
---------- ------------------------------------------------------------ ------------------------------------------------------------
  1 /opt/oracle/oradata/orcl11g/system01.dbf   SYSTEM
  2 /opt/oracle/oradata/orcl11g/sysaux01.dbf   ONLINE
  3 /opt/oracle/oradata/orcl11g/undotbs01.dbf   ONLINE
  4 /opt/oracle/oradata/orcl11g/users01.dbf   ONLINE
  5 /opt/oracle/oradata/orcl11g/zbdba.dbf   ONLINE
  6 /opt/oracle/oradata/orcl11g/zbdba01.dbf   RECOVER
  7 /opt/oracle/oradata/orcl11g/test.dbf    ONLINE

但是我们归档已经丢失，无法完成介质恢复：

SYS@orcl11g>recover datafile 6;
ORA-00279: change 1986632 generated at 10/28/2014 05:16:11 needed for thread 1
ORA-00289: suggestion : /opt/oracle/flash_recovery_area/ORCL11G/archivelog/2014_10_28/o1_mf_1_74_b4yqrglr_.arc
ORA-00280: change 1986632 for thread 1 is in sequence #74


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

ORA-00308: cannot open archived log '/opt/oracle/flash_recovery_area/ORCL11G/archivelog/2014_10_28/o1_mf_1_74_b4yqrglr_.arc'
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3

所以这时候我们直接修改文件头进行online：

[oracle@ogg1 lib]$ bbed parfile=par.txt

比较简单的就是用指令进行恢复，但是这个得看情况，很多人恢复不了。然后笨的方法就是用MiniTool数据恢复工具这些免费数据恢复软件进行恢复，当然后面的耗时比较长

文件可以用软件恢复的，个人推荐你用安易，，数据恢复软件。彻底删除的文件，永久删除的文件也支持的。常见的卸载软件丢失的数据，硬盘被格式化了或者提示未被格式化要恢复文件，u盘内存卡等也支持恢复。软件恢复的很全面，值得一用。
