Oracle数据库的导入与导出问题

Oracle数据库的导入与导出最好按照用户进行导入和导出。

举例来说：

1、导出：

cmd命令窗口

exp sim/sim@bhgd file=e:\oracle\export\expsim.dmp log=e:\oracle\export\expsim.log owner=sim

2、在目标数据库建立于源数据相同的用户

CREATE TABLESPACE SSDX DATAFILE 'E:\oracle\oradata\BHGD\ssdx.DBF' SIZE 500M AUTOEXTEND ON NEXT 10M MAXSIZE 30000M;

CREATE TEMPORARY TABLESPACE SSDXTEMP TEMPFILE 'E:\oracle\oradata\BHGD\ssdxtemp.DBF' SIZE 100M AUTOEXTEND ON NEXT 10M MAXSIZE 5000M;

CREATE USER SIM IDENTIFIED BY sim DEFAULT TABLESPACE SSDX TEMPORARY TABLESPACE SSDXTEMP;

GRANT CONNECT,RESOURCE TO SIM;

GRANT CREATE ANY PROCEDURE TO SIM;

GRANT CREATE ANY SEQUENCE TO SIM;

GRANT CREATE ANY VIEW TO SIM;

GRANT CREATE SESSION TO SIM;

GRANT SELECT ANY DICTIONARY TO SIM;

3、imp sim/sim@bhgd file=e:\oracle\export\expsim.dmp fromuser=sim touser=sim
