Hi,
Are you using consistent =y and do you need to - if you can avoid this may
assist with avoiding the ora-1555 errors.
Hacking the export views was mentioned.
Have a look at http://www.orafaq.com/maillist/oracle-l/2005/05/23/1299.htm for
an earlier posting by me on how this can be done and also a reply by Chris
Marquez suggesting that in certain circumstances you may be able to achieve the
desired affect by taking tablespaces offline.
HTH,
Bruce Reardon

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.
