【说明】
示例脚本，完成如下功能：
1）创建表空间EAS_D_HFY121009_STANDARD和临时表空间EAS_T_HFY121009_STANDARD、用户hfy120910；
2）创建用于备份还原的目录zdir；
3）完成从源数据库hfy备份并还原到新的数据库hfy120910；

【脚本】

------ begin 创建用户和表空间 ------------
CREATE TABLESPACE "EAS_D_HFY121009_STANDARD" DATAFILE '/oracle/oradata/dbeas/EAS_D_HFY121009_STANDARD.ORA' SIZE 2000M;

------ end 创建directory ------------

------ begin 备份还原 ------------
$ expdp hfy/*** directory=zdir schemas=hfy dumpfile=hfy121009.dmp logfile=hfy121009exp.log

$ impdp hfy121009/*** directory=zdir schemas=hfy remap_schema=hfy:hfy121009 remap_tablespace=EAS_D_HFY_STANDARD:EAS_D_HFY121009_STANDARD dumpfile=hfy121009.dmp logfile=hfy121009imp.log
------ end 备份还原 ------------

注意：在数据库还原时，如果目标数据库没有表空间EAS_D_HFY_STANDARD，则一定要加上参数：remap_tablespace=EAS_D_HFY_STANDARD:EAS_D_HFY121009_STANDAR，否则会报错：找不到表空间。
