aslo  before i do the impdp
I will create a directory
sql> create  directory test_dir as 'C:\exportdp';
and grant the privs to the user on this direcoty.

and then run the
impdp me/pas remap_schema=usr1:usr2 direcoty= test_dir?

 

by: mrjoltcolaPosted on 2009-09-04 at 10:03:32ID: 25261458

To do remap_schema you need to be DBA

impdp system/admin remap_schema=usr1:usr2 directory=test_dir dumpfile=usr1.dmp

 

by: AndytwPosted on 2009-09-04 at 10:04:35ID: 25261465

don't forgot that you also need to specify the name of the DMP file(s). So:

Note:  Unprivileged users can only perform schema remaps if the target schema is their schema.  This may be an issue for you, since the above in not true in your post (target schema is USR2, *not* ME).  Privileged users have no schema mapping restrictions.

impdp me/pass REMAP_SCHEMA=usr1:usr2 DIRECTORY=test_dir DUMPFILE=export_file.dmp

Actually, no I was wrong. DBA is not a required priv to use REMAP_SCHEMA. I just tested from a regular user successfully.

As long as the user has permissions to import, the remap_schema option can be used.

 

by: mrjoltcolaPosted on 2009-09-04 at 10:11:40ID: 25261534

Ah, thanks, Andytw, for correcting me. I did not refresh before posting.

I sort of suspected as such right after posting, I am too hasty with advice sometimes.

 

by: mrjoltcolaPosted on 2009-09-04 at 10:13:50ID: 25261555

Another difference, I also just tested, apparently with data pump, we no longer have the old import restriction of "Only a DBA can import a file created by another DBA". There seems to be no such restriction with data pump.

I created a directory data_dt and created a user  ABC grant read ,write on directory data_dt to user ABC, also user ABC has fill import database priv and aslo dba priv
I have datain the location d:\exp\backup' directory and
created directory as mentioned above as
create directory data_dt as 'D:\exp\backup'

c> impdp abc/xxxx remap_schema=usr1:usr2  directory=data_dt  dumpfile=expfile.dmp
what do you see wrong here?

 

by: AndytwPosted on 2009-09-04 at 15:44:08ID: 25263962

taaz:  I don't see anything wrong there.  Why do you think it's wrong, are you getting an error?  Can you post the details of the error?

 

by: taazPosted on 2009-09-04 at 18:31:39ID: 25264576

yes it is

C:\Documents and Settings\1>impdp dcd0014/paki remap_schema=CUST:CUST_NEW dir

select * from dba_directories

In the original question you said you were creating "test_dir", not "test"

 

by: AndytwPosted on 2009-09-05 at 03:57:34ID: 25265716

No points for this comment, just an additional observation ...
>> ORA-39070: Unable to open the log file.
Running IMPDP in this case is trying to generate a log file (default import.log, in the directory specified by the DIRECTORY parameter) for the session since the default of the parameter NOLOGFILE is Y, and you've not specified that parameter.  

Either way, IMPDP cannot read the dumpfile, or create the log file.  

mrjoltcola is correct, show us the results of DBA_DIRECTORIES
