由于导出和导入时需要关注索引是否被导入，进行实验。

本实验主要目的是理解content的两个参数项：date_only和metadata_only，其中涉及include。

1.分别使用以下三种方式导出分区表ACTIVE_PARTITION的数据、元数据

expdp  scott/scott

directory=HOME_O

dumpfile=scott_expdp1.dmp

logfile=scott_expdp1.log tables=ACTIVE_PARTITION

expdp  scott/scott

directory=HOME_O

dumpfile=scott_expdp2.dmp

logfile=scott_expdp2.log tables=ACTIVE_PARTITION content=data_only

expdp  scott/scott

directory=HOME_O

dumpfile=scott_expdp3.dmp

logfile=scott_expdp3.log tables=ACTIVE_PARTITION content=metadata_only

[oracle@ogg2 ~]$

expdp  scott/scott  directory=HOME_O   dumpfile=scott_expdp1.dmp  logfile=scott_expdp1.log

tables=ACTIVE_PARTITION

3.使用第一种方式导出的数据，导入时索引和数据都会被导入

5.content=metadata_only表示只导入结构，不导入数据；而content=data_only是只导入数据。两者依次导入则等同于不加该参数。

如果需要在导入时排除索引，可以添加其他参数。

下面使用exclude=index是无效的，从导入日志可以看到导入了CONSTRAINT，因此主键索引、唯一键索引都被导入了

注意，这时只看到了scott下的索引，scott2下是没导入的。

include参数的格式为：

INCLUDE =

object_type[:name_clause] [, ...]

其中object_type指定了可以包含的对象类型，可以通过以下视图查看：

全局   select OBJECT_PATH?from

DATABASE_EXPORT_OBJECTS;

用户级 select

OBJECT_PATH?from SCHEMA_EXPORT_OBJECTS  ;

表级   select OBJECT_PATH?from

TABLE_EXPORT_OBJECTS   ;

name_clause是可选的，可以用双引号包含具体的对象名称。

根据官方文档建议(utility

87页)：最好使用参数文件来包含此类需要添加较多双引号的参数。

如：

hr.par文件内容为：

SCHEMAS=HR

DUMPFILE=expinclude.dmp

DIRECTORY=dpump_dir1

LOGFILE=expinclude.log

INCLUDE=TABLE:"IN

('EMPLOYEES', 'DEPARTMENTS')"

INCLUDE=PROCEDURE

INCLUDE=INDEX:"LIKE

'EMP%'"

指定的导出(导入)语句为：

expdp hr

PARFILE=hr.par
