篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Oracle Data Pump Schema 方式导入导出相关的知识，希望对你有一定的参考价值。
实验环境准备
利用OCI上的Oracle数据库image建立3套单实例数据库环境，SYS口令为Ora_DB4U，普通用户口令为Welcome1：
| 数据库环境/主机名 | 版本 | 公网IP | 私网IP | DB_NAME | CDB | PDB |
|---|---|---|---|---|---|---|
| 源数据库1/db122-noncdb | 12.2 | 138.3.221.188 | 10.0.0.15 | NONCDB12 | N | N/A |
| 源数据库2/db122-cdb | 12.2 | 158.101.152.60 | 10.0.0.107 | CDB12 | Y | ORCLPDB1 |
| 目标数据库/db19-cdb | 19c | 158.101.67.212 | 10.0.0.203 | DB19 | Y | ORCLPDB1 |
源数据库是指需要迁移的数据库，目标数据库指需要迁往的数据库。
源数据库上均安装了Oracle示例Schema。安装方法请参见如何使用github安装Oracle 数据库12c Sample Schema （示例Schema）。
源数据库中对象的情况如下：
system@ORCLPDB1> select owner, count(*) from dba_objects where owner in
(select username from all_users where ORACLE_MAINTAINED = 'N') group by owner order by owner;
OWNER COUNT(*)
-------------------- ----------
BI 8
HR 34
IX 58
OE 142
PM 22
SH 310
6 rows selected.
3个数据库服务器均开放1521端口：
firewall-cmd --add-port=1521/tcp --permanent
firewall-cmd --reload
# firewall-cmd --list-all
public
target: default
icmp-block-inversion: no
interfaces:
sources:
services: dhcpv6-client ssh
ports: 1521/tcp
protocols:
masquerade: no
forward-ports:
source-ports:
icmp-blocks:
rich rules:
3个数据库服务器均通过/etc/hosts设置了主机名解析：
10.0.0.15 db122-noncdb
10.0.0.107 db122-cdb
10.0.0.203 db19-cdb
3个数据库服务器均在oracle用户根目录下建立了dumpdir目录：
$ id -un
oracle
$ cd ~
$ mkdir dumpdir
实验1：Data Pump实现Schema迁移
源数据库：db122-cdb上的orclpdb1中的所有用户Schema
目标数据库：db19-cdb上的orclpdb2
源数据库服务器上的操作
准备data pump参数文件export.par：
[oracle@db122-cdb dumpdir]$ cat export.par
DIRECTORY=my_data_pump_dir
DUMPFILE=dumpfile%U.dmp
LOGFILE=logfile.log
SCHEMAS=HR,OE,PM,IX,SH,BI
EXCLUDE=STATISTICS
LOGTIME=ALL
METRICS=YES
FLASHBACK_TIME=SYSTIMESTAMP
PARALLEL=4
FILESIZE=5G
定义目录：
sys@CDB12> alter session set container=orclpdb1;
sys@CDB12> create directory my_data_pump_dir as '/home/oracle/dumpdir';
执行导出：
[oracle@db122-cdb dumpdir]$ expdp \\"sys/Ora_DB4U@orclpdb1 as sysdba\\" parfile=export.par
