Oracle 11g Impdp和Expdp问题

Question

I used expdp user1\\user1@orcl DUMPFILE=user.dmp for exporting.

The export was success.

but when i tried on another oracle 11 DB to import impdp user2\\user2 DUMPFILE=user.dmp it start to search for user1 and try to import in that user1

I want to import that in user2. Can anyone help.

i cannot create a network_link , as i get this file from a another vendor which will not provide be rights to a network link but i need to import his dmp file in another user in my database

Use remap_schema parameter to import data to other schema. The use is simple: remap_schema=old_name:new_name .

To import to another database you need to use network_link parameter. But before that, you need to add entry in your tnsnames.ora , for example:

 imphost =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = /*PUT ADDRESS HERE*/)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = /*PUT SERVICE NAME HERE*/)
    )
  )

Next, connect to your database and create database link with CREATE PUBLIC DATABASE LINK imphost USING 'imphost' . Now you should run you should run impdp dumpfile=user.dmp network_link=imphost remap_schema=user1:user2 - I never tried that before, so it's only a guess based on this article .
