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

查询发现仍然导入了user表空间
$ sqlplus bjbbs/passwd

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

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

至此数据即被导入到正确的用户表空间中了。 |
