Question

在我的Oraclle 11.2中，我有一个架构MAIN，其中500个表分布在5个表空间中。 TBS1中有100个表，TBS2中有100个表等等...用户MAIN的默认值是TBS1。

有时由于某种原因我必须导出架构MAIN

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

并将其导回到相同的表空间

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

但导入后我在一个默认TBS1中有所有对象

我如何执行impdp以便将表格导出到导出之前的原始表空间？我哪里错了？

谢谢。

老实说，我不知道您实际上在做什么，但是那不是datapump的工作原理。如果表是用不同的表空间定义的，则除非指定了TRANSFORM或REMAP_TABLESPACE，否则导入将保留原始规范。否则，它将按预期工作

SQL> grant create table to my_test ;

Grant succeeded.

SQL> create table my_test.test_one_tbs ( c1 number ) tablespace tbrepdata ;

Table created.

SQL> create table my_test.test_two_tbs ( c1 number ) tablespace tbhisdata ;

Table created.

SQL> declare
