查看datafile也看不出什么蹊跷。

可能是什么其他的地方吧。

我用如下的sql导处数据文件的状态。

select f.tablespace_name||'|'||f.file_name||'|'||f.autoextensible||'|'||f.bytes/1024/1024||'M' ||'|'|| t.initial_extent||'|'||t.next_extent||'|'||t.extent_management||'|'||t.segment_space_management||'|'||t.bigfile from dba_tablespaces t,dba_data_files f where t.tablespace_name=f.tablespace_name;

结果如下：

TBS1|/u01/app/oracle/oradata/disk_1/tbs01.dbf|NO|5M|1048576|1048576|LOCAL|AUTO|N
O

SYSAUX|/u01/app/oracle/oradata/disk_4/sysaux01.dbf|NO|325M|65536||LOCAL|AUTO|NO
UNDOTBS|/u01/app/oracle/oradata/disk_5/undotbs01.dbf|YES|200M|65536||LOCAL|MANUAL|NO

SYSTEM|/u01/app/oracle/oradata/disk_4/system01.dbf|NO|325M|65536||LOCAL|MANUAL|NO

EXAMPLE|/u01/app/oracle/oradata/disk_5/example.dbf|YES|400M|1048576|1048576|LOCAL|AUTO|NO

INDX|/u01/app/oracle/oradata/disk_5/indx.dbf |NO|40M|65536||LOCAL|AUTO|NO

最后一行的 indx.dbf后面还有个空格，原来是这个文件导致的！！！

我有个好习惯，之前执行的语句都保留了下来，一翻，验证了我的想法。

create tablespace example datafile '/u01/app/oracle/oradata/disk_5/example.dbf' size 400M autoextend on maxsize 4g extent management local uniform. size 1M;

create tablespace indx datafile '/u01/app/oracle/oradata/disk_5/indx.dbf 'size 40M;

接下来该处理这个问题了。

        10--文件号是10
/u01/app/oracle/oradata/disk_5/indx.dbf

SQL> alter database datafile 10 offline;

Database altered.

SQL> alter database rename file '/u01/app/oracle/oradata/disk_5/indx.dbf ' to '/u01/app/oracle/oradata/disk_5/indx.dbf'
  2  ;
alter database rename file '/u01/app/oracle/oradata/disk_5/indx.dbf ' to '/u01/app/oracle/oradata/disk_5/indx.dbf'

貌似我写的文件空格不够标准？？？

SQL> select '|'||file_name||'|' from dba_data_files where file_id=10;

'|'||FILE_NAME||'|'

还是不行，晕了，这个问题还真是费劲啊。

这样做，

[oracle@oel1 disk_5]$ ll
total 54856
-rw-r----- 1 oracle dba  5251072 Oct 30 18:01 indx.dbf
drwxr-x--- 4 oracle dba     4096 Oct 30 10:27 PODD
-rw-r----- 1 oracle dba 20979712 Oct 30 08:34 temp01.dbf
-rw-r----- 1 oracle dba 50339840 Oct 30 18:01 tools.dbf
[oracle@oel1 disk_5]$ mv indx* indx.dbf1

SQL> alter database datafile 10 offline;

Database altered.

SQL> alter database rename file '/u01/app/oracle/oradata/disk_5/indx.dbf ' to '/u01/app/oracle/oradata/disk_5/indx.dbf1'
  2  ;

Database altered.
终于搞定了。

第5遍开始做dg

这次很快。中途抛了几个ORA错误提提神，影响不啊，最后终于看到了一个对号。

查看后台，正常了。
