摘要：
场景：1。将数据库从OperatingSystem用户导入到新创建的用户LsOperateSystem用户，将数据库从Gsyl用户导入到新建用户LsZhmz用户，创建命名空间和用户LsOperatingSystem，并授权createtablespaceLsOperateSystemdatafile'E:toolspaceorclLsOperaeSystem.DBF'size50Mauto
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;
