import does not work

Hi,

I created a scehma/user 'xyz_user' using command

create user xyz_user identified by password;

and granted following privileges to it like

grant resource, exp_full_database, imp_full_database,create session to xyz_user;

I imported a schema dump file 'Database_Dumpfile_1'supplied by client with data, structure into xyz_user  using command

imp xyz_user/password full=y file=Database_Dumpfile_1.dmp

Later I made some changes to table structure, data.

Now when I tried to export latest updated schema back to dump file 'Database_Dumpfile_2' to deliver back to the client using usual old command

exp xyz_user/password indexes=n full=y file=Database_Dumpfile_2.dmp

It is exporting entire database( including all schemas) instead of just required single 'xyz_user' schema .

so i introduced

 owner='(xyz_user)'

to export only the specific schema.

Now at client end when we try to import this dump file
using command

imp client_user/password full=y file=Database_Dumpfile_2.dmp

giving error message like 'cannot open the dump file'.

Do i need to introduce
 owner='(xyz_user)' in the import statement as well? when I introduced it like

imp client_user/password full=y owner='(xyz_user)' file=Database_Dumpfile_2.dmp it did not like it, says check help section for correct options etc.

(Note:
Earlier i used use following privilege command
GRANT all privilege TO xyz_user  WITH ADMIN OPTION
 which never gave issues like this and used to export only single schema instead of entire database with all schema
)

How can I import this dump file. What is the command i should use for this. Any sample code, ideas, resources, links highly appreciated. Thanks in advance.

Here are few points you need to take care of:
 

1.  Verify if the export is done sucessfully by examining the log file.  If the file says something like 'Export terminated sucessfully' means there was no problem during export

2.  During import see if you are specifying the correct path (It is the export dump as in step 1).  Here too, log it and examine the log file.
 

You can view help of imp/exp by entering exp help=y or imp help=y
 

3.  The command for export with owner is
 

exp uid/pwd@instance file=<exppath> owner=<ownername> log=explog.log
 

4.  The command for import with owner is

imp uid/pwd@instance fromuser=<owner> touser=<ownername_to_loadtables> file=<exppath_from_step1> implog.log statistics=none buffer=10000000 commit=y

Import: Release 10.2.0.1.0 - Production on Mon Apr 13 21:04:01 2009

 How can i pass through this message and import successfully. I am executing these commands from command prompt as usual by going to the folder location wherever the dump file Database_Dumpfile_2  is, in my windows xp machine. Please advise.

do you have "exp_full_database" and "imp_full_database" roles to do the export and import?
Have you done the exp/imp before or is this the first time?

do you have the DBA roles assigned to you? or, the user that you're using for export and import has the DBA roles/privileage?
