Oracle 将一个转储文件导入多个表空间

在我的Oracle11.2中，我有一个主模式，500个表分布在5个表空间中。TBS1中有100个表格，TBS2中有100个表格等等。。。用户MAIN的默认值是TBS1

有时出于某种原因，我不得不导出主模式

expdp \'/ as sysdba\' schemas=main dumpfile=main.dmp directory=dpdumps

并将其导入回相同的表空间

impdp \'/ as sysdba\' directory=dpdumps dumpfile=main.dmp version=11.2

但是在导入之后，我将所有对象都放在一个默认TBS1中

我如何执行impdp以使表与导出前一样到达原始表空间？ 我错在哪里

谢谢。

老实说，我不知道您实际上在做什么，但数据泵不是这样工作的。如果表是用不同的表空间定义的，除非指定了

TRANSFORM

或

REMAP\u表空间

，否则导入将保留原始规范。否则，它将按预期工作

这些是您使用的全部命令行（除了拼写

schemas

错误之外）？比如说，你没有一个

TRANSFORM

参数，或者一个做任何额外工作的参数文件？这些是你使用的全部命令行（除了拼写
