oracle 数据库复制

场景：     

1、从OperateSystem用户下将数据库导入到新创建用户LsOperateSystem用户下，从Gsyl用户下将数据库导入到新创建用户LsZhmz用户下 创建命名空间和用户LsOperateSystem，并授权

create tablespace LsOperateSystem datafile 'E:	ools	ablespaceorclLsOperateSystem.DBF' size 50M autoextend on next 10m maxsize unlimited;

create user LsOperateSystem identified by 000000 default tablespace LsOperateSystem;

grant connect,resource to LsOperateSystem;

grant dba to LsOperateSystem;

创建命名空间和用户LsOperateSystem，并授权

create tablespace LsZhmz datafile 'E:	ools	ablespaceorclLsZhmz.DBF' size 50M autoextend on next 10m maxsize unlimited;

create user LsZhmz identified by 000000 default tablespace LsZhmz;

grant connect,resource to LsZhmz;

grant dba to LsZhmz;

2、创建数据库目录，并授权给用户

create directory oracleDB4 AS 'E:oracleDB'; --（执行一次即可）

grant read ,write on directory oracleDB4 to LsOperateSystem; 

grant read ,write on directory oracleDB4 to LsZhmz; 

3、从原有用户下导出数据库

expdp OperateSystem/000000@orcl schemas=OperateSystem directory=oracleDB4 dumpfile=OperateSystem.DMP logfile =OperateSystem.LOG;

expdp Gsyl/000000@orcl schemas=Gsyl directory=oracleDB4 dumpfile=Gsyl.DMP logfile =Gsyl.LOG;

4、将原有用户导出的数据导入新用户

impdp LsOperateSystem/000000 directory=oracleDB4 dumpfile=OperateSystem.dmp REMAP_SCHEMA=OperateSystem:LsOperateSystem EXCLUDE=USER full=y;

impdp LsZhmz/000000 directory=oracleDB4 dumpfile=Gsyl.dmp REMAP_SCHEMA=Gsyl:LsZhmz EXCLUDE=USER full=y;
