环境：Oracle Linux Server release 6.4 oracle 11.2.0.1.0

问题描述与分析：经常会有在建立表空间时，在数据文件命名时中间或结尾处多个空格，该如何将这名字里面的空格去掉呢，下面我们实验如何去掉。改名思路：将表空间offline，系统级rename，数据库级rename，表空间online，检查数据。

1. 创建测试表空间

sys@ORCL>create tablespace aaa datafile '/11g/app/oracle/oradata/ORCL/aaa bbb.dbf' size 10m;

Tablespace created.

2. 将表空间offline

sys@ORCL>alter tablespace aaa offline;

Tablespace altered.

3. 直接修改数据文件名字报错

sys@ORCL>alter database rename file '/11g/app/oracle/oradata/ORCL/aaa bbb.dbf' to '/11g/app/oracle/oradata/ORCL/aaabbb.dbf';

alter database rename file '/11g/app/oracle/oradata/ORCL/aaa bbb.dbf' to '/11g/app/oracle/oradata/ORCL/aaabbb.dbf'

*

ERROR at line 1:

ORA-01511: error in renaming log/data files

ORA-01141: error renaming data file 8 - new file '/11g/app/oracle/oradata/ORCL/aaabbb.dbf' not

found

ORA-01110: data file 8: '/11g/app/oracle/oradata/ORCL/aaa bbb.dbf'

ORA-27037: unable to obtain file status

Linux-x86_64 Error: 2: No such file or directory

Additional information: 3

4. 修改操作系统级数据文件名字

[oracle@test ORCL]$ mv aaa\ bbb.dbf aaabbb.dbf

[oracle@test ORCL]$ ls

aaabbb.dbf redo01.log SYSAUX01.DBF TEST.DBF wmis01.dbf

control01.ctl redo02.log SYSTEM01.DBF UNDOTBS01.DBF

EXAMPLE01.DBF redo03.log temptbs01.dbf USERS01.DBF

5. 修改数据库级数据文件名字

sys@ORCL>alter database rename file '/11g/app/oracle/oradata/ORCL/aaa bbb.dbf' to '/11g/app/oracle/oradata/ORCL/aaabbb.dbf';

Database altered.

6. 将数据文件online

sys@ORCL>alter tablespace aaa online;

Tablespace altered.

sys@ORCL>select name from v$datafile where file#=8;

NAME

----------------------------------------------------------------------------------------------------

/11g/app/oracle/oradata/ORCL/aaabbb.dbf

总结：此次测试主要是在系统级改名字与在数据库级改名字，谁在前谁在后问题。上面我举了错误顺序的例子和报错。生产库改前最好还是弄个备份，DBA的救命稻草，有备无患！
