RE: Export import problem

Not sure of what your export parameters are but a better option is to count objects after the import rather than size

select count(*), object_type from dba_objects where owner='PSI' group by object_type;

select count(*), object_type from dba_objects where owner='PSI_DUP' group by object_type; (or use owner in)

For the export check the estimate option for expdp which tells you how big the export file is likely to be

A expdp command for a copy schema might be

nohup expdp system/password schemas=PSI flashback_scn=96209618 directory=EXPORTS dumpfile= PSI_EXPDAT_131208.DMP logfile= PSI_EXPDP_131208.LOG estimate=blocks &

copy the dmp file to the IMPORT directory if it is different from EXPORT

nohup impdp system/password schemas=PSI remap_schemas=PSI_DUP directory=IMPORT dumpfile=PSI_EXPDAT_131208.DMP logfile=PSIDUP_IMPDP_131208.LOG &
