如何把資料導入不同的表空間?

很多人在進行資料遷移時，希望把資料導入不同于原系統的表空間，在導入之後卻往往發現，資料被導入了原表空間。

本例舉例說明解決這個問題:

1.如果預設的使用者具有DBA權限

那麼導入時會按照原來的位置導入資料，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.回收使用者unlimited tablespace權限

這樣就可以導入到使用者預設表空間

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
