RE: Snapshot too old

Hi Tom,

Are you aware of the ORA-1555 prevention techniques described in my web tip "Avoiding ORA-1555 Errors "
(http://www.ixora.com.au/tips/admin/ora-1555.htm)?

Subject:	Snapshot too old

We are having trouble exporting a database with several large, insert-active
tables. Exporting these tables causes a 1555 "Snapshot too old" error.  The
error message says use larger rollback segments. I doubled the size of our rollback segs but I don't want to make them all bigger just for one occasional
export.

Is there a way to create a and use a very large rollback segment just for the
export? How would you approach solving this problem - this is a production database and taking it off-line is probably not possible.

tia,

..tom
