Creating your database in a different file structure
Duplicating your database using a different structure is very easy to be done using Data Pump; all you need to do is use the parameter REMAP_DATAFILE
on your import command as shown in the following example:
$ impdp fcomunoz/alvarez@pdborcl directory=datapump dumpfile=diff_structure_06192013.dmp remap_datafile='/u01/app/oracle/oradata/pdborcl/datafile_01.dbf':' /u01/app/oracle/oradata/pdborcl2/datafile_01.dbf'
