I'm trying to export my schema TOM.

exp TOM/TOM@ORCL file=c:\exp_tom.dmp log=c:\exp.log

but I can export only tables with rows. Each table with zero rows is not exported.

Should I set some parameter to export all the tables?

Thanks in advance!

I just test using the exact command you provided on a schema I just created and it works:

Can you post your log?

C:\>exp bob/bob file=bob log=bob

"Each table with zero rows is not exported."  With 11gR2 the segments with 0 rows only get their DDL exported.  Segments with 0 bytes are treated differently in 11gr2.

With 11g there may not be extents allocated.
Try this:

 Alter table  TABLENAME to allocate extents

You can also create a script for all tables:

select 'alter table '||table_name||' allocate extent;'
from user_tables
where segment_created = 'NO'
