** export excluding some tables -- JApplewhite 2006-06-15
Use this simple SQL to generate the
Tables= list of your *.par file. Just remove the comma from the first
table in the list.
Select ',' || Table_Name
From User_Tables
Where Table_Name Not In (<TablesToExcludeList>)
Order By Table_Name
/
We have over 100,000 tables in our Student
Info. System so we're constantly using the above SQL to generate a *.par
file with a Tables= list of the ones we want to export. Usually we
use patterns such as Table_Name Like '____5___' to get the ones we
want. We've found that you can list up to about 32,000 tables in
the list before Export barfs - at least in 9i.
It's easy. Hope it helps.

Hi,
I am trying to take an export of whole database
but it fails due to some big tables with rollback segment eror Ora-1555.
I know we can specify tables but is there a way to exclude certain tables.
Thanks for your help.
I find that dropping the tables prior to exporting seems to work.
Other than that, the only other workable method I have found
is to include only the tables I do want to export (tables=(t1,t2,t2...)
This may require more than one export if the command line becomes
too long. Cumbersome, but it works.
If the number of tables is really large, you could use sql to generate
your export commands. This saves some typing, and is less error
prone than manually inputting all the table names.
The first method ticks off the users, so I generally avoid it.
