一、介绍实验使用的例子

1.创建一个实验环境

先创建一个名字叫user_testtbs的表空间

SQL> create tablespaceuser_testtbs

2  datafile '/oradata/DB196/datafile/user_testtbs01.dbf' size 20M

3  autoExtend on;

Tablespace created.

在表空间下创建一个名字叫user_test的用户密码是user_test1234

SQL> create user user_test identified by user_test1234 default tablespaceuser_testtbsQUOTA unlimited ONuser_testtbs;

User created.

在这个用户下创建一个叫user_test.t_class的表

SQL> create table user_test.t_class

2

(name varchar2(20) not null,

3

age  number(20),

4  id

number(20),

5

sex  varchar2(5))

6

tablespaceuser_testtbs;

Table created.

给出一个导出文件的路径并且给这个路径设置好权限

# mkdir /expdp

chown -R oracle:oinstall  /expdp

chmod 777 /expdp

然后给这个用户各种授权啊

SQL> grant CREATE SESSION    TO user_test;

grant CREATE TRIGGER    TO user_test;

Grant succeeded.

创建一个路径，并且命名，这个路径叫exppump

SQL>create or replace directory exppump as '/expdp';

SQL>grant read,write on directory exppump

to user_test;

SQL>alter tablespaceuser_testtbsread only;

SQL>exec

sys.dbms_tts.transport_set_check(' user_testtbs',true);

SQL>select * from sys.transport_set_violations;

SQL>

Grant succeeded.

SQL> grant CREATE SEQUENCE   TO user_test;

Grant succeeded.

SQL> grant CREATE CLUSTER    TO user_test;

Grant succeeded.

SQL> grant CREATE TYPE       TO user_test;

Grant succeeded.

SQL> grant CREATE PROCEDURE  TO user_test;

Grant succeeded.

SQL> grant CREATE TABLE      TO user_test;

Grant succeeded.

SQL> grant CREATE INDEXTYPE  TO user_test;

Grant succeeded.

SQL> grant CREATE OPERATOR   TO user_test;

Grant succeeded.

SQL> grant CREATE VIEW       TO user_test;

对着这张表插入一堆没用的数据

SQL> insert into t_class values(

'dd',18,1,'man');

1 row created.

SQL> insert into t_class values(

'hl',28,2,'man');

1 row created.

SQL> insert into t_class values(

'hl',28,2,'man');

1 row created.

SQL> insert into t_class values(

'hl',28,2,'man');

1 row created.

SQL> insert into t_class values(

'hl',28,2,'man');

1 row created.

2.按照表的方式来导出

查看一下这个hl.dbf的文件到底有多大

@TORCL1:/home/oracle\/vi

expdp.par

userid='dbmgr/dba4only'用户密码

directory=exppump路径的名字刚才已经创建了这个路径 这里表现出一个结果

dumpfile=t_class.dmp导出来的文件名

filesize=21M文件的大小 命令是du -h /要导出文件的路径和文件名

parallel=4并行导出

version= 11.2.0.3.0这个比较关键 就是12C导出11G必须填写正确的版本号

tables=user_test.t_class导出的表 说清楚是哪个用户下的哪个表

job_name=expdp_user_test起个名字 自己好记住 不然系统默认给个怪异的名字不好记

Logfile=expdp.log日志名

@TORCL1:/home/oracle\/expdp parfile=expdp.par

create tablespace user_testtbs

datafile

autoExtend on;

Tablespace created.

SYS@ENMOEDU> create user user_test
