标签：value err global copyright limited fse 不一致 error select

SYS@orcl11g>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须要介质恢复

SYS@orcl11g>select file#,name,status from v$datafile;
     FILE# NAME                                                         STATUS

         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

可是我们归档已经丢失，无法完毕介质恢复：

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: {<RET>=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改动文件头进行online：
