《Oracle简单常用的数据泵导出导入(expdp/impdp)命令举例(下)》

目的：指导项目侧自行进行简单的数据泵迁移工作。

本文实验环境：Oracle 11.2.0.4，利用数据库自带的scott示例用户进行试验测试。

1.首先需要创建Directory

2.使用expdp导出用户数据

2.1 只导出scott用户的元数据，且不包含统计信息；
2.2 只导出scott用户的数据；
2.3 只导出scott用户下的emp，dept表及数据；
2.4 只导出scott用户下的emp，dept表结构；
2.5 导出scott用户下所有的内容；
2.6 并行导出scott用户下所有的内容；

3.查询当前用户用到的表空间

特别注意：如果后续要导入的数据库版本低，所有导出命令就需要在后面加一个version=指定版本。

例如11g -> 10g，假设10g具体版本为10.2.0.1，那么就加一个版本的参数version=10.2.0.1。

1. 首先需要创建Directory

这里目录名字定义为"jy"，
若是windows平台，对应系统目录为"E:\jingyu";

create or replace directory jy as 'E:\jingyu';

若是Unix/Linux平台，对应系统目录为"/tmp/jingyu".

create or replace directory jy as '/tmp/jingyu';

注意：目录在系统上需要真实存在（mkdir -p /tmp/jingyu），且有访问的权限。

drwxr-xr-x. 2 oracle oinstall 4.0K May 22 16:48 jingyu

2. 使用expdp导出用户数据

2.1 只导出scott用户的元数据，且不包含统计信息；

expdp system directory=jy schemas=scott content=metadata_only exclude=statistics dumpfile=scott_meta.dmp logfile=scott_meta.log

$ expdp system directory=jy schemas=scott content=metadata_only exclude=statistics dumpfile=scott_meta.dmp logfile=scott_meta.log

2.2 只导出scott用户的数据；

2.3 只导出scott用户下的emp，dept表及数据；

这里如果用scott用户导出，需要注意scott用户对于directory的权限问题：需要dba用户赋予scott用户read,write目录的权限。
即：grant read, write on directory jy to scott;

SQL> grant read, write on directory jy to scott;

Grant succeeded.
