ORA-39039: Schema expression "IN ('TEST_REP')" contains no valid schemas.

Question

Hi,
I am new to administration and using Datapump for the first time. My question might sound silly..
Here is my requirement.
I have 2 tables sarath9700.table1 and test_rep.table1 in the same schema. I was asked to export import data from sarath9700.table1 to test_rep.table1.
Enter user-name: sqlplus / as sysdba
Enter password:
sqlplus sys/director AS SYSDBA

It fails with

How to get rid of this.. Am I doing something wrong here??

Hi,
I missed one thing on the impdp command. It should be:
impdp test_rep/test_rep tables=sarath9700.test26 directory=TEST_DIR dumpfile=EMP_DEPT2.dmp logfile=expdpEMP_DEPT2.log remap_schema=sarath9700:test_rep CONTENT=DATA_ONLY
Actually, it looks like you exported table1, not test26. Here is your export command:
expdp sarath9700/sarath9700 tables=table1 directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=expdpEMP_DEPT.log
The table that you exported is sarath9700.table1 as can be seen in the out put from expdp:
. . exported "SARATH9700"."TABLE1" 6.132 KB 31 rows
So, this is the table that you need to specify on the impdp command:
impdp user/password tables=sarath9700.table1 ...
You can remap the schema so the table goes into a different schema, but with 10.1, you can't rename the table.
remap_schema=old_schema:new_schema
Hope this helps.
