标题: exp/imp小练习

环境：平台分别是REDHAT 5.5和WINDOWS SP3，ORACLE数据库都是11gr2

一、导入表
1.在windows环境中，用用户SCOTT下创建一张新表并插入一些数据
SQL> conn scott/tiger
已连接。
SQL> create table aa(name varchar2(20));

表已创建。

SQL> insert into aa values('james');

已创建 1 行。

SQL> insert into aa values('wade');

已创建 1 行。

SQL> insert into aa values('bosh');

已创建 1 行。

SQL> commit;

提交完成。

SQL> select * from aa;

NAME
--------------------
james
wade
bosh

2.导出表aa
C:\Documents and Settings\Administrator>exp scott/tiger file=f:\exp\exp_table.dmp tables=(aa);

Export: Release 11.2.0.3.0 - Production on 星期二 10月 16 15:56:23 2012

连接到: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
已导出 ZHS16GBK 字符集和 AL16UTF16 NCHAR 字符集

即将导出指定的表通过常规路径...
. . 正在导出表 AA导出了 3 行
导出成功终止, 但没有警告。

3.查看linux中SCOTT用户没有表aa
SQL> conn scott/tiger
Connected.
SQL> select table_name from tabs;

TABLE_NAME
------------------------------
DEPT
EMP
BONUS
SALGRADE

4.将导出文件上传到linux中

5.进行导入
[oracle@dbserver ~]$ imp scott/tiger file=/home/oracle/exp_table.dmp tables=aa

Import: Release 11.2.0.1.0 - Production on Tue Oct 16 16:05:12 2012

Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production

Export file created by EXPORT:V11.02.00 via conventional path
import done in US7ASCII character set and AL16UTF16 NCHAR character set
import server uses ZHS16GBK character set (possible charset conversion)
export client uses ZHS16GBK character set (possible charset conversion)
. importing SCOTT's objects into SCOTT
. importing SCOTT's objects into SCOTT
. . importing table "AA" 3 rows imported
Import terminated successfully without warnings.

6.进行确认
[oracle@dbserver ~]$ sqlplus scott/tiger

SQL*Plus: Release 11.2.0.1.0 Production on Tue Oct 16 16:05:53 2012

二、导入用户模式
1.在linux中的oracle上新建一个用户james并授予相应权限
[root@dbserver ~]# su - oracle
[oracle@dbserver ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Tue Oct 16 15:11:18 2012

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> create user james identified by james ;

User created.

SQL> grant connect,resource to james;

Grant succeeded.

2.用用户james登录创建一张表并插入一些数据
SQL> conn james/james
Connected.
SQL> create table lbj(id number);

Table created.

SQL> insert into lbj values(23);

1 row created.

SQL> insert into lbj values(34);

1 row created.

SQL> insert into lbj values(55);

1 row created.

SQL> commit;

Commit complete.

SQL> select * from lbj;

3.导出用户james
[oracle@dbserver ~]$ exp system/oracle owner=james file=/home/oracle/exp_owner.dmp

Export: Release 11.2.0.1.0 - Production on Tue Oct 16 15:16:41 2012

4.在windows中的oracle上创建用户james并授予同样的权限
C:\Documents and Settings\Administrator>sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on 星期二 10月 16 15:30:26 2012

连接到:

With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> create user james identified by james ;

User created.

SQL> grant connect,resource to james;

Grant succeeded.

5.用james登录并确定他没有表

SQL> conn james/james
已连接。

SQL> select table_name from tabs；
未选定行。

6.将linux中导出的文件拷贝到windows中

7.进行导入
C:\Documents and Settings\Administrator>imp system/oracle fromuser=james touser=james file=f:\exp\exp_owner.dmp

Import: Release 11.2.0.3.0 - Production on 星期二 10月 16 15:23:00 2012

连接到: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production

经由常规路径由 EXPORT:V11.02.00 创建的导出文件
已经完成 ZHS16GBK 字符集和 AL16UTF16 NCHAR 字符集中的导入
导出客户机使用 US7ASCII 字符集 (可能的字符集转换)
. 正在将 JAMES 的对象导入到 JAMES
. . 正在导入表 "LBJ"导入了 3 行
成功终止导入, 没有出现警告。

8.用james登录确认导入成功
SQL> conn james/james
已连接。

SQL> select table_name from tabs;

TABLE_NAME
------------------------------
LBJ

SQL> select * from lbj;
        ID

F:\DATABASE\INSTALL\ORADATA\ORCL\USERS01.DBF
F:\DATABASE\INSTALL\ORADATA\ORCL\EXAMPLE01.DBF

SQL> create tablespace dbkj datafile 'F:\DATABASE\INSTALL\ORADATA\ORCL\dbkj01.d
f' size 10m;

表空间已创建。

2.新建一个用户并指定其默认表空间
SQL> create user dj identified by dj default tablespace dbkj;

用户已创建。

SQL> grant connect,resource to dj;

授权成功。

3.用新建用户创建新表并插入数据
SQL> conn dj/dj
已连接。
SQL> create table tt(name varchar2(10),age number);

表已创建。

SQL> insert into tt values ('james',27);

已创建 1 行。

bosh               30
kobe               33

4.将表空间离线准备导出
SQL> conn / as sysdba
已连接。
SQL> alter tablespace dbkj read only;

表空间已更改。

5.导出表空间
C:\Documents and Settings\Administrator>exp system/oracle tablespaces=dbkj file=f:\exp_tbs.dmp log=f:\exp_tbs.log
