很多人在進行數據遷移時,希望把數據導入不同于原系統的表空間,在導入之后卻往往發現,數據被導入了原表空間。
本例舉例說明解決這個問題:
1.如果缺省的用戶具有DBA權限
那么導入時會按照原來的位置導入數據,即導入到原表空間
$ imp bjbbs/passwd file=bj_bbs.dmp fromuser=jive touser=bjbbs grants=n

查詢發現仍然導入了USER表空間
$ sqlplus bjbbs/passwd

2.回收用戶unlimited tablespace權限
這樣就可以導入到用戶缺省表空間
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
