Home -> Community -> Mailing Lists -> Oracle-L -> RE: two databases in a server
Oh, how I like to see these type of discussions on the mailing list...
The *philosophy* here is to place *many* databases on one server. Lots of reasons, and lots of benefits... But I do enjoy seeing the other opinions out there as it provides fuel for my fire drills :-)

Generally it's bad because there is a certain level of resource consumption for an instance of any size. So pay the price ONCE and have an instance large enough to do all the work needed by all the applications using the database. There can be cases where multiple instances on the same box are needed, but many cases that I have seen it was not needed. Many times folks can use one instance (or at least fewer instances) to get the work done.

I've heard the argument before about having more than one instance on a machine is a bad idea.
However, on the flip side, having 50 applications share one instance can
be bad, as if one app needs a particular patch, you're affecting 49
other
applications due to one application's requirements.
Anyone care to elaborate why more than one instance is bad?
