本实验注意模拟在不同的schema、tablespace,使用remap_schema和remap_tablespace参数
1.RAC端导出数据
[oracle@rac01 backup]$ expdp c##hbhe0316/wwwwww schemas=c##hbhe0316 directory=backup dumpfile=tbs02_20211003.dmp logfile=20211003dmp.log

2.单实例端创建测试表空间、用户。
SQL> create tablespace tbs02 datafile '/oradata/ORCL/tbs02.dbf' size 1024m;
Tablespace created.
SQL> create user c##hbhe0317 identified by wwwwww default tablespace tbs02 temporary tablespace temp;
User created.
SQL> grant dba to c##hbhe0317;
Grant succeeded.
SQL> grant connect to c##hbhe0317;
Grant succeeded.
SQL> grant resource to c##hbhe0317;
Grant succeeded.
SQL> conn c##hbhe0317/wwwwww
Connected.
3.将导出的数据scp至单机环境
[oracle@rac01 backup]$ scp tbs02_20211003.dmp 192.168.56.100:/oradata/backup
4.导入数据至单实例环境
[oracle@db01 backup]$ impdp c##hbhe0316/wwwwww directory=backup remap_schema=c##hbhe0316:c##hbhe0317 remap_tablespace=tbs01:tbs02 dumpfile=tbs02_20211003.dmp

Connected.
SQL> select count(*) from t1;
