今天上班发现公司测试库的temp表空间数据文件包增到11g ，询问开发说昨天作了数据库压力测试.出于磁盘空间考虑，重新把temp表空间数据文件做小.

SQL> select FILE_NAME,TABLESPACE_NAME from dba_temp_files;

FILE_NAME
--------------------------------------------------------------------------------
TABLESPACE_NAME
------------------------------
/opt/oracle/product/9i/oradata/cwt/temp01.dbf
TEMP

[oracle@localhost cwt]$ ls -lh
total 13G

-rw-rw---- 1 oracle dba 11G Mar 20 14:58 temp01.dbf

[@more@]

SQL> ALTER DATABASE TEMPFILE '/opt/oracle/product/9i/oradata/cwt/temp01.dbf' DROP
2 INCLUDING DATAFILES;

Database altered.

SQL> select FILE_NAME,TABLESPACE_NAME from dba_temp_files;

no rows selected

SQL> ALTER TABLESPACE temp
2 ADD TEMPFILE '/opt/oracle/product/9i/oradata/cwt/temp01.dbf' SIZE 100m reuse;

Tablespace altered.

SQL> select FILE_NAME,TABLESPACE_NAME,bytes/1024/1024/1024 from dba_temp_files;

FILE_NAME
--------------------------------------------------------------------------------
TABLESPACE_NAME BYTES/1024/1024/1024
------------------------------ --------------------
/opt/oracle/product/9i/oradata/cwt/temp01.dbf
