1,源数据库执行导出

alter session set container=DXGTKJGH;
select tablespace_name from dba_tablespaces;
表空间信息：DXGTKJGH
创建导出目录：
create or replace directory dmp as '/home/oracle/dump';
expdp system/Oracle_123@10.41.1.233/DXGTKJGH dumpfile=DXGTKJGH.dmp directory=dmp SCHEMAS=DXGTKJGH

2,目标数据库执行导入

alter session set container=KYQGL;
select tablespace_name from dba_tablespaces;
表空间信息：KYQGL
create or replace directory dmp as '/home/oracle/dump';
新表空间：KYQGL 用户信息：KYQGL
impdp system/Oracle_123@10.41.1.233/KYQGL dumpfile=DXGTKJGH.dmp directory=dmp REMAP_SCHEMA=DXGTKJGH:KYQGL remap_tablespace=DXGTKJGH:KYQGL
