oracle数据泵从11g迁移数据库到12c的PDB(expdp/impdp)

均在服务器端

oracle11g数据导出
–创建目录
先在D盘创建物理路径D:\dump
进入sqlplus

sqlplus / as sysdba

创建逻辑目录

create or replace directory dir as 'D:\dump';

–授权

grant read,write on directory dir to SZGW_YS;

–查询

select * from dba_directories;

退出sqlplus

ctrl+c

–导出

expdp SZGW_YS/SZGW_YS@orcl schemas=SZGW_YS dumpfile=SZGW_YS.dmp DIRECTORY=dir

–删除

drop directory dir;

数据导入Oracle12C
–登录cdb

sqlplus system/cnten as sysdba

–查询当前容器

show con_name

–查询容器中所有pdb

show pdbs

–创建pdb数据库

CREATE pluggable DATABASE pdborcl admin USER pdbadmin identified BY pdbadmin roles=(connect)
file_name_convert= ('C:\app\Administrator\oradata\orcl\pdbseed', 'C:\app\Administrator\oradata\orcl\pdborcl');  

–切换到pdb数据库

alter session set container=pdborcl

–打开数据库

alter database open

–创建目录
先在c盘创建物理目录C:\dump
并将导出的DMP文件存放到该目录下

 create or replace directory dir as 'C:\dump';

–查询

select * from dba_directories;

–1：创建临时表空间

 create temporary tablespace SZGW_YS_TEMP
 tempfile 'C:\app\Administrator\oradata\orcl\tablespace\SZGW_YS_TEMP.dbf'
 size 50m
 autoextend on
 next 50m maxsize 20480m
 extent management local;

–创建数据表空间

 create tablespace SZGW_YS_DATA
 datafile 'C:\app\Administrator\oradata\orcl\tablespace\SZGW_YS_DATA.dbf'
 size 50m
 autoextend on
 next 50m maxsize 20480m
 extent management local;

–删除用户

drop user SZGW_YS cascade;

–第3步：创建用户并指定表空间

create user SZGW_YS identified by SZGW_YS default tablespace SZGW_YS_DATA temporary tablespace SZGW_YS_TEMP; 

–第4步：给用户授予权限

grant connect,resource,dba to SZGW_YS;

–授权

grant read,write on directory dir to SZGW_YS;

–查看目录及权限

SELECT privilege, directory_name, DIRECTORY_PATH FROM user_tab_privs t, all_directories d
 WHERE t.table_name(+) = d.directory_name ORDER BY 2, 1;

–退出sqlplus

ctrl+c

–使用impdp导入SZGW_YS数据

impdp SZGW_YS/SZGW_YS@pdborcl directory=dir dumpfile=SZGW_YS.DMP TABLE_EXISTS_ACTION=replace version='11.2.0.1.0' transform=segment_attributes:n

remap_tablespace=tbs_hr:tbshr 原来表空间:新的表空间
remap_schema=hr:hradm 原来的schema:现在的schema
transform=segment_attributes:n 去掉表空间和存储子句，加上这个参数后，remap_tablesapce参数就会失效，就会倒进用户默认的表空间，
