Home -> Community -> Mailing Lists -> Oracle-L -> RE: 20 Instances 1 Machine
Greg - Why do you run 10-30 instances on a machine? Is it technical or
business factors? Thanks.

We do Enterprise Server Resource Sharing here..
We have boxes with 10-30 instances running on them. In some cases, we will split machine/resources up into domains. And in some cases-there are all of the databases running on a machine.
In either case, it takes quite a bit of planning to implement this type of environment. you should engage the SA's (OS, hardware, and storage). We have a plan here that allows us to implement many instances on the same machine that prevents mistakes. We also have these machines in a SUN Clustered environment so that there is some sense of "HA" involved...
Good Luck
Greg

I would recommend a Sun E-15k. The best option would be to domain it into separate virtual boxes so that each instance has it's own space. Or, you could go the other route and buy a bunch of Ultra-2 machines and give each database its own box. Or, maybe a blade for each instance?

You also have to consider the OS overhead. Putting 20 instances means hundreds of processes. Just managing all this at the system level can be resource consuming.
