OK, two 9.2 databases. Your subject line says you also have two (or more) Oracle homes, but you don't need that to support two databases at the same level.

I'm assuming from your mention of "the Services directory" that this is on a Windows system.

Why do you want two listeners?

How are you trying to start your db?

There is a lot of missing info here, but it sounds to me like you're trying to run two Oracle homes to support two databases, even though those databases are at the same level. If I'm right about that, I'd forget about the second Oracle home. One Oracle home will support mutliple databases. And even if the databases are (and need to be) at different levels -- neccisitating multiple Oracle homes, you can still service them all with a single listener.

If you are -- and need to -- run multiple homes, you have to make sure all of your environment variables and registry entries are correct for the one you are working with at any given moment.
