(although if the site is migrating to CBO, I would prefer to just go back to
the RBO as a safer emergency solution, if not migrating then what the hell
happened to all the stats bar one table)

His "Contrary to the pontifications of theoreticians and ivory-tower
academics, there are many silver bullets for Oracle performance tuning"
comments could possible by aimed at yours truly, for which I would be deeply
flattered for the complement. However as I work full-time as a DBA dealing
with real databases in real production environments solving real problems
(how I wish it was always as simple as Don's examples), I might
unfortunately be mistaken.

I was about to write a response akin to what you are saying here. I must be doing something wrong. I never get called to performance problems where the cause and solution are so elementary. I too would not call them silver bullets but a case of the DBA being asleep at the wheel, or more likely no DBA at the wheel at all. Maybe someone got sold a software that uses oracle as the storage back end and the powers who sign the cheque were told that a database is like an electronic filing cabinet, so the secretary or receptionist got the honorary title of DBA. No insult meant to secretaries and receptionists.
