Sadly this is one of those "How long is a piece of string" questions, It relates to what are you doing with those databases what support is required on a daily basis for those databases
I can have a single database that requires 2 full time DBA's and another DBA supporting 20 or 50 databases. It also comes down to the available management tools that you have to do set analysis tasks like mining the alert logs for errors. Apparently the book "Implementing and Managing Oracle Databases" has a chapter to assist in answering this question. I think one of the best ways to get a understanding on this is to show your manager what it is you do each day by doing a time and motion study on yourself, something like 8 am checked alert logs on databases 930 am Checked tablespace utilisation 10am increased xxx tablespace on xxxx database 1030 worked with Finance to tune new ad hoc query ( ie used for corporate BI tool) and so on Also you might like to see if having some management tools would simplify any processes to free up time and provide a list of tools, how they make you more efficient and the proposed cost of such tools. You can then say that the tools whilst useful still aren't going to be able to recover those 3 mission critical databases if they were to crash when you are 2 continents away skiing or surfing.

I have put together the usual reasons, but they want "Industry Standards", like how many Databases can one DBA manage. Or how many GB/DBA or endusers/DBA? Does anyone keep these kind of stats? thanks __________________________________________________ Do you Yahoo!?
