RE: two databases in a server

Alex,  

This is funny. What you call extreme I call normal. I have an IBM AIX p570 as a development machine with 15 Oracle databases on it. And a P690 with twice that. Right now they all share the same Oracle home
(although we are finally applying the January security patches using a
new Oracle home).  

Very stable. Reboot time is what I would call normal (less than 1 minute). The databases are always available - never down.  

So I guess I disagree with your assessment. The big machines (in my view) are the better machines for me.  

Tom

Subject: Re: two databases in a server  

Hi Tom,  

These are two extreme.

I would prefer in this case something in the middle - like 5 machines each hosting 6 DBs. Here you can flexibility to group them to get more convenient maintenance windows as well as limit system outage impact.  

Cheers,

        Michael,         

        What you say is the reason the PC as database server revolution is

        slowly dieing out. Many servers means many licenses. One large server

        means one larger license. There is a significant cost savings.         

        And as you said, manageability. I would much rather manage 30 databases

        on one server than thirty servers and thirty databases.         

        Separate Oracle Homes where needed, and we are in business!         

        Tom
