And there's the rub.

When you outsource db management, if they bill by the hour, then they have no qualms with choosing an architecture which has technical advantages but requires more hours to manage.

Even if they don't bill hourly, it's to their advantage to architect an environment that is technically "perfect" but highly complex... it reduces their liability and increases cost of management - and in the long run, you will pay for the complexity not them.

I would fight hard to keep things as simple as possible while meeting your business needs. And as Seth pointed out, there is plenty of competition in the managed services space - so if your current provider isn't able to meet your needs as a business then you should be able to find *someone* out there who can.


PS... listener per database is actually very common, although personally i wouldn't default to this on a new system without justification. you lose all the benefits of scan! gns seems less common but scan gets used a lot and i think it's got some great advantages. but again, there's that "standards" discussion which is important.
