ORACLE 删除用户及空闲表空间释放空间
(2011-03-10 10:44)
第一步：删除过期用户
- DROP USER colin CASCADE;
第二步：查询过期用户相关的表空间是否还有对象
- SELECT OWNER, SEGMENT_NAME, SEGMENT_TYPE, TABLESPACE_NAME
-
FROM DBA_SEGMENTS
-
WHERE TABLESPACE_NAME IN
-
(SELECT TABLESPACE_NAME
-
FROM DBA_TABLESPACES
- WHERE TABLESPACE_NAME LIKE '%COLIN%')
第三步：转移过期用户表空间上的对象到其他表空间
- ALTER TABLE tab_colin MOVE TABLESPACE colin_song_tbs;
-
- ALTER INDEX idx_tab_colin REBUILD TABLESPACE colin_song_idx_tbs;
第四步：查询无对象的表空间
- SELECT 'DROP TABLESPACE ' || TABLESPACE_NAME ||
-
' INCLUDING CONTENTS AND DATAFILES;'
-
FROM DBA_TABLESPACES
-
WHERE NOT EXISTS (SELECT 12
-
FROM DBA_SEGMENTS
-
WHERE DBA_SEGMENTS.TABLESPACE_NAME =
- DBA_TABLESPACES.TABLESPACE_NAME);
第五步：删除之 把上述查询出来的语句贴到文本编辑里检查下（PS:这里会包含一个temp的临时表空间一定要去掉啊)
- SQL> drop tablespace STAT_FTFY_CHRGSTAY_DTBS including contents and datafiles;
-
-
Tablespace dropped
-
SQL> drop tablespace STAT_FTFY_CHRGNEW_WIXTBS including contents and datafiles;
-
-
Tablespace dropped
-
SQL> drop tablespace STAT_FTFY_CHRGSMR_MIXTBS including contents and datafiles;
-
- Tablespace dropped
最后去看下你的系统空间应该释放了吧
