Creating db with multiple homes

We have a total of 7 NT servers, each hosting multiple Oracle databases. Most of them are running 8.0.5, while one is running 7.4 and 8.0.5 and one test machine is running 8.0.5 and 8.1.5. I have been somewhat out of the picture for all of the 8.x work, and the DBA who did the 8.x installations is gone. Now I have been tasked with upgrading all of our 8.0 databases to 8.1.5 (8i). I am pretty confused over how these multiple homes work (see other postings I’ve made today regarding multiple homes at the client end). With both 8.0 and 8.1 installed on a server (or worse, with these two in addition to 7.4) how does one distinguish between creating an 8.0 database vs. creating an 8.1 database? What is it exactly that makes a database one version or the other? With software for multiple versions installed on a server, how does database startup and operation distinguish which is correct for a given database?

If all these questions are answered in a fairly direct way in the fine manual(s) just point me to where. If not, all input is appreciated.
