We can import an object from the database to a different database and a different tablespace with a different schema.
1. First, let’s get this done using the data transfer method.

$ impdp directory=data_pump_dir network_link=cclink tables=EMRAH.MUSTERILER remap_schema=EMRAH:EMRAH remap_tablespace=DENEME:USERS logfile=remap.log; Import: Release 11.2.0.1.0 - Production on Mon Nov 3 18:17:06 2014 Copyright (c) 1982, 2009, Oracle and/or its affiliates.

If we question the result.

SQL> select OWNER, TABLESPACE_NAME from dba_tables where table_name='MUSTERILER'; OWNER TABLESPACE_NAME ------------------------------ ------------------------------ EMRAH USERS |
2. We can export the table and export it to a different schema and tablespace.
First, let’s “export” a table from the database named “cc”.

Then we send the “DUMP” file to the data_dump_dir folder of the database named “catalog” with scp.

$ scp /u01/app/oracle/admin/cc/expimp_dir/ulke.dmp oracle@172.20.31.232:/u01/app/oracle/admin/catalog/dpdump/ oracle@172.20.31.232's password: ulke.dmp 100% 92KB 92.0KB/s 00:00 |
Let’s “import” to our database named “catalog”.
