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 &

Subject: Export import problem
Hi all,
I have one requirement, ie. to create a schema PSI_DUP same as PSI (existing).
I did export the PSI schema first and later created PSI_DUP similar to PSI.
Overall schema size is showing as 10GB where as When i do export import I am
not getting the import successful with warnings.
Could you please help me if any suggestions?
