Martin, whilst those comments are valuable I think they are missing my
fundamental point that a customer choice can be changed by Oracle with no real
warning. I have seen this happen on a production system of ours a couple of
times as well as on performance test databases.

You may want to try a shell script that monitors free space in the recovery
area. It's also possible that you've set a guaranteed restore point and forgot
about it? Or maybe the db_flashback_retention_target is larger than it needs to
be? Just some things to look at without knowing your requirements.

I believe that there is a fundamental flaw in how flashback is managed in a
database.
If I make the decision, based on business requirements and technical reasons,
that I want flashback logging to be enabled for a database then I would expect
that to remain the situation.
However Oracle can disable flashback and not really inform the user at all. Yes
there is a message in the alert log
