本实验是关于data 的exp 一个用户scott 下面imp到另外一个用户中。

---------
在instance = sheng 的导出scott.emp

[Oracle@aoracle ~]$ exp scott/oracle tables=emp file='/u01/rman/file01.txt';

下面imp到另外一个用户的table 中。

下面建立另外一个user：
SQL> select name from v$tablespace;

NAME
------------------------------
SYSTEM
UNDOTBS2
SYSAUX
USERS
TEMP

SQL> create tablespace TB_DBS datafile '/u02/sheng/tbsdbs01.dbf' size 20m;

Tablespace created.

SQL> select name from v$tablespace;

NAME
------------------------------
SYSTEM
UNDOTBS2
SYSAUX
USERS
TEMP
TB_DBS

6 rows selected.

SQL> create user dbs identified by dbs default tablespace tb_dbs;

User created.

SQL> select username,account_status from dba_users where username like 'DBS%';

USERNAME ACCOUNT_STATUS
------------------------------ --------------------------------
DBSNMP OPEN
DBS OPEN

下面连一下：
SQL> CONN DBS/DBS
ERROR:
ORA-01045: user DBS lacks CREATE SESSION privilege; logon denied

Warning: You are no longer connected to ORACLE.

SQL> grant create session ，resource to dbs;

Grant succeeded.

SQL> conn dbs/dbs
Connected.
SQL> select * from tab;

no rows selected

SQL>

好，，下面把scott 用户下的emp table imp 到dbs 用户下：

[oracle@aoracle ~]$ imp system/manager file='/u01/rman/file01.txt' fromuser=scott touser=dbs;
