Multiple DBs on one server
In order to save some money on licensing costs, our Global Systems Director (a non technical pharmacist!) is proposing rolling up our 3 exisiting Oracle 9i systems onto one server, and proposing we put a new fourth (as yet unknown) large system on the same machine. Don't underestimate his clout within the organisation - he rarely listens to others for advice (and never asks for it).
I'm agog and aghast at the prospect: I can see performance dipping hugely and the prospect of a minor problem taking out all 4 production systems at once.
I need to be fully prepared for when we meet and discuss this. I have no idea what this new fourth system does or how it does it so I can't explain to him how it might affect the other systems. Hows the best way of preparing for this? Are there any obvious arguments I can use? Any good technical resources I can look at?
Re: Multiple DBs on one server
Do you have enough memory on that server to hold 4 databases?
