Leslie,

Looks like the when exported, your 'one table' was already allocated 1.8G. Most likely you did not use the compress=N(the default is compress=Y) in your export which resulted in all extents used in export source to be compressed into 1 extent when imported. So now when you give Alter Table... Deallocate Unused, it can deallocate unused extents but not the initial extent which is 1.8G. The same might be true for the rest...

Hi all,

I have an export file of 6M. The import file only has DDL. I imported the file into a db of about 1G. After import, the db became 6G !!! There is one table with 71 columns, but NO DATA, takes 1.8G !!! How does this happen, and how to make the objects claim the space. I issued Alter Table ... Deallocate Unused, but doesn't help. Also how to prevent this from happening.

Both the export and import database are 815 on Sun5.6. The export db has 8K block size, while import db has 2K. Here is the par file:

USERID=arbor/arbor123
FROMUSER=ARBOR

TOUSER=ARBOR
COMMIT=TRUE
IGNORE=TRUE

FILE=arbor_full_20010726.dmp
LOG=Afull.log

Thank you!

Leslie
