oracle12c 數據遷移 expdp impdp pdb

Oracle11g數據庫遷移到Oracle12C的PDB（使用impdp/expdp）
alter pluggable database hrdb close immediate;
DROP PLUGGABLE DATABASE hrdb INCLUDING DATAFILES;

--一、數據備份
mkdir /oradata/dumpdir
--創建目錄
create or replace directory exp_dir as '/oradata/dumpdir';
--授權
grant read,write on directory exp_dir to hradm;

--查詢
select * from dba_directories;

expdp admin/admin file=hr.dmp directory=exp_dir schemas=hradm;

--刪除
drop directory exp_dir;


---二、數據導入Oracle12C
--登錄cpcdb
$sqlplus sys/[email protected]:1531/hrdb as sysdba

--創建目錄
create or replace directory exp_dir as '/oradata/dumpdir';
--授權
grant read,write on directory exp_dir to hradm;



--查詢
select * from dba_directories;

--創建tbscpc表空間

create tablespace tbshr
datafile '/oradata/edw/hrdb/hrdb-001.dbf'
size 2G
autoextend on
next 64m maxsize 20G
segment space management auto
extent management local;

alter tablespace tbshr
add datafile '/oradata/edw/hrdb/hrdb-002.dbf' size 2G
autoextend on
next 50m maxsize 20G;

alter tablespace tbshr
add datafile '/oradata/edw/hrdb/hrdb-003.dbf' size 2G
autoextend on
next 50m maxsize 20G;


--給cpcadm和admin授權，並修改默認表空間
grant dba,resource to hradm;
select * from dba_users where username='HRADM';
alter user hradm default tablespace tbshr;

alter database default tablespace tbshr;

create user admin identified by admin;
grant connect,dba to admin;

--使用impdp導入hrdb數據

impdp admin@hrdb directory=exp_dir dumpfile=hr20180401004000.DMP remap_tablespace=tbs_hr:tbshr remap_schema=hr:hradm schemas=hr table_exists_action=replace transform=segment_attributes:n

remap_tablespace=tbs_hr:tbshr 原來表空間:新的表空間
remap_schema=hr:hradm 原來的schema:現在的schema
transform=segment_attributes:n 去掉表空間和存儲子句，加上這個參數後，remap_tablesapce參數就會失效，就會倒進用戶默認的表空間，
