Question : User_Segments

Hello

I am using Oracle XE on Linux. I took export from my schema using rows=N which exported a blank schema.

I imported that to a new server. My tables are empty but when I check the segment size the show many MBs for each table? Why is so? Is there a way to reduce the size?


select segment_name, sum(bytes/1024/1024) mb
from user_segments
group by segment_name
order by 2 desc;

Here are first few rows:

SEGMENT NAME                                        SEGMENT_TYPE       MB

SALES_ORDER_PROCESSES_PK            INDEX                         28
ITEMS                                                           TABLE                        14
ITEM_STATIONS_CMB_IDX                        INDEX                        12
ITEM_STATIONS                                          TABLE                        11

When I check if there is any data in a table:


select count(*) from items;

It returns 0.


Any help will be appreciated.

As I mention in my comment : http:#33136694
use like
exp Poracle/oracle file='pt.dmp' tables='PT' rows=N COMPRESS=N

You miss "Rows=N" in your Export command
and then import table.

IMP SCOTT/TIGER FILE='pt.dmp'  ROWS=N FROMUSER=Poracle TOUSER=SCOT
