I assume you intend to also:
.5) Clone database to second machine
.6) Drop all objects in schema on 2nd machine 4.5) Take cold backup of 1st machine

With those caveats, it looks fine.

Hi,

We have to defragment one of our production databases..(objects are not properly sized)..
Since i can't shutdown database for more than 2 hrs and database is read only and DML
statements run thru batch jobs 2 days in month. We r thinking of using the following scheme.

1. export the particular application schema name NMDD of production database.
2. On second machine run the DDL script which creates all the objects with proper sizing.
3. Import the data from export taken in step 1.
4. take the cold backup of 2nd machine.
5. copy the backup files from 2nd machine to production machine.....

Is there any better way to get rid of fragmentation without using any third party tool..
or Is there any flaw in above procedure.

Thanks
-Harvinder
