Hopefully, you will have got your tnsnames problems sorted out by now. However, the advice to only use one listener and to use the highest version of Oracle software is pretty sound - if you intend to run all your databases (on that server) using the same listener.

I have a clustered server system to look after and each 'package' can failover between cluster nodes in the event of a problem. I have one listener per database and that one listener is running with the same version of Oracle as the database itself.

Obviously, I cannot have 'hundreds' of listeners all called LISTENER, so they each have individual names like Horace and Stella or Derek and Rachel.

Only kidding :o) The names are related to the package name - that makes it easy to identify them and also to auto start them in the package start-up scripts.

So, you *can* run many listeners at many different versions of Oracle.

Cheers,
Norman.
