Answer / nirav gajjar

The "ORA-01555 snapshot too old" error, which causes user
transactions to fail, is a nightmare for Oracle DBAs and
developers. It usually occurs after queries or batch
processes have been running for a long time, which means
you can lose many hours of processing when the error crops
up.
