文档课题：oracle数据泵+dblink 不落盘导单表的测试.
源 端：oracle 19.13 数据库实例(tmis) IP(192.168.133.101) 单实例
目标端：oracle 19.13 数据库实例(orclcdb) IP(192.168.133.101) 多租户
1、数据确认
1.1、源端数据
leo@TMIS> show user;
USER is "LEO"
leo@TMIS> select * from fruits;
F_ID S_ID F_NAME F_PRICE
---------- ---------- ------------------------------ ----------
a1 101 apple 5.2
b1 101 blackberry 10.2
bs1 102 orange 11.2
bs2 105 melon 8.2
leo@TMIS> select * from books;

leo@TMIS> select TABLE_NAME,tablespace_name from user_tables where table_name in ('BOOKS','FRUITS');
TABLE_NAME TABLESPACE_NAME
-------------------- --------------------
BOOKS USERS
FRUITS USERS
1.2、目标端数据
leo@ORCLPDB> select * from fruits;
F_ID S_ID F_NAME F_PRICE
---------- ---------- ------------------------------ ----------

leo@ORCLPDB> select TABLE_NAME,tablespace_name from user_tables where table_name in ('BOOKS','FRUITS');
TABLE_NAME TABLESPACE_NAME
-------------------- --------------------
BOOKS USERS
FRUITS USERS
2、导入前准备
2.1、源端建连接用户
sys@TMIS> create user ogg identified by ogg;
User created.
sys@TMIS> grant connect,resource,unlimited tablespace,dba to ogg;
Grant succeeded.
--测试ogg用户的连通情况.
[oracle@leo-oracle-19c admin]$ sqlplus ogg/ogg@tmis

OK (10 msec)
2.2、目标端建导入用户
sys@ORCLCDB> show con_name
CON_NAME
------------------------------
ORCLPDB
sys@ORCLCDB> drop user ogg;
User dropped.
sys@ORCLCDB> create user ogg identified by ogg;
User created.
sys@ORCLCDB> grant connect,resource,unlimited tablespace,dba,IMPORT FULL DATABASE TO ogg;
Grant succeeded.
[oracle@leo-oracle-19c ~]$ sqlplus ogg/ogg@192.168.133.101:1521/orclpdb
SQL*Plus: Release 19.0.0.0.0 - Production on Mon Jul 29 14:52:59 2024

Version 19.13.0.0.0
ogg@ORCLPDB> show con_name
CON_NAME
------------------------------
ORCLPDB
2.3、目标端建dblink
2.3.1、tnsnames.ora文件
确保tnsnames.ora有如下内容：
TMIS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = leo-oracle-19c)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = tmis)
)
)
sys@ORCLCDB> sho con_name
CON_NAME
------------------------------
ORCLPDB
2.3.1、建dblink
sys@ORCLCDB> create public database link TMIS_LINK connect to ogg identified by ogg using 'TMIS';
Database link created.
--测试dblink.
sys@ORCLCDB> select * from leo.fruits@TMIS_LINK;
F_ID S_ID F_NAME F_PRICE
---------- ---------- ------------------------------ ----------
a1 101 apple 5.2
b1 101 blackberry 10.2
bs1 102 orange 11.2
bs2 105 melon 8.2
sys@ORCLCDB> select * from leo.books@TMIS_LINK;

2.4、目标端建directory
sys@ORCLCDB> create directory impdp_dir as '/home/oracle/dump';
Directory created.
sys@ORCLCDB> grant read,write on directory impdp_dir to public;
Grant succeeded.
2.5、编辑导入脚本
[oracle@leo-oracle-19c ~]$ cat impdp.sh
#!/bin/bash
export ORACLE_SID=orclcdb
impdp ogg/ogg@192.168.133.101:1521/orclpdb \
network_link=TMIS_LINK \
remap_schema=LEO:LEO \
tables=leo.fruits,leo.books \
REMAP_TABLESPACE=USERS:USERS \
table_exists_action=replace \
directory=impdp_dir \
parallel=8 \
job_name=impdp#LEO.job \
logfile=impdp#LEO.out
[oracle@leo-oracle-19c ~]$ sh impdp.sh
