The UNDO tablespace should not be used much in an import as most of the activity is inserts and these should not cause a lot of undo activity. Are you sure you have dropped all indexes in the table(s) involved and are creating objects from the import itself as opposed to adding to them? Also: make sure all triggers are disabled on such tables or you may inadvertently be doing more than needed.

Commit=y should help.

If you really want to extend the UNDO, then check none of its datafiles has exceeded its maximum file size. Received on Thu Jun 25 2009 - 02:14:34 CDT
