本文教你如何把数据导入不同的表空间……
问：我在进行数据迁移时，本来希望把数据导入到不同于原系统的表空间，在导入之后意外的发现数据却被导入了原表空间。请问应给怎么解决这个问题?
答：我来举一个简单的例子:
首先如果缺省的用户具有DBA权限，那么导入时会按照原来的位置导入数据，即导入到原表空间。
| $ imp bjbbs/passwd file=bj_bbs.dmp fromuser=jive touser=bjbbs grants=n Import: Release 8.1.7.4.0 - Production on Mon Sep 22 11:49:41 2003 (c) Copyright 2000 Oracle Corporation. All rights reserved.

查询发现仍然导入了USER表空间
| $ sqlplus bjbbs/passwd SQL*Plus: Release 8.1.7.0.0 - Production on Mon Sep 22 11:50:03 2003 (c) Copyright 2000 Oracle Corporation. All rights reserved. Connected to: Oracle8i Enterprise Edition Release 8.1.7.4.0 - 64bit Production With the Partitioning option JServer Release 8.1.7.4.0 - 64bit Production SQL> select table_name,tablespace_name from user_tables; TABLE_NAME TABLESPACE_NAME ------------------------------ ------------------------------ HS_ALBUMINBOX USERS HS_ALBUM_INFO USERS HS_CATALOG USERS HS_CATALOGAUTHORITY USERS HS_CATEGORYAUTHORITY USERS HS_CATEGORYINFO USERS HS_DLF_DOWNLOG USERS ... JIVEWATCH USERS PLAN_TABLE USERS TMZOLDUSER USERS TABLE_NAME TABLESPACE_NAME ------------------------------ ------------------------------ TMZOLDUSER2 USERS 45 rows selected. |
2.回收用户unlimited tablespace权限即可以导入到用户缺省表空间
| SQL> create user bjbbs identified by passwd 2 default tablespace bjbbs 3 temporary tablespace temp 4 / User created. SQL> grant connect,resource to bjbbs; Grant succeeded. SQL> grant dba to bjbbs; Grant succeeded. SQL> revoke unlimited tablespace from bjbbs; Revoke succeeded. SQL> alter user bjbbs quota 0 on users; User altered. SQL> alter user bjbbs quota unlimited on bjbbs; User altered. SQL> exit Disconnected from Oracle8i Enterprise Edition Release 8.1.7.4.0 - 64bit Production With the Partitioning option JServer Release 8.1.7.4.0 - 64bit Production |
最后重新导入数据
| $ imp bjbbs/passwd file=bj_bbs.dmp fromuser=jive touser=bjbbs grants=n Import: Release 8.1.7.4.0 - Production on Mon Sep 22 12:00:51 2003 (c) Copyright 2000 Oracle Corporation. All rights reserved.

Import terminated successfully without warnings. SQL> select table_name,tablespace_name from user_tables; TABLE_NAME TABLESPACE_NAME ------------------------------ ------------------------------ HS_ALBUMINBOX BJBBS HS_ALBUM_INFO BJBBS HS_CATALOG BJBBS HS_CATALOGAUTHORITY BJBBS .... JIVETHREAD BJBBS JIVETHREADPROP BJBBS JIVEUSER BJBBS JIVEUSERPERM BJBBS JIVEUSERPROP BJBBS JIVEWATCH BJBBS PLAN_TABLE BJBBS TMZOLDUSER BJBBS TABLE_NAME TABLESPACE_NAME ------------------------------ ------------------------------ TMZOLDUSER2 BJBBS 45 rows selected. |
至此数据即被导入到正确的用户表空间中了。
