Re: shared server or dedicated server -- How to find ?

Don't worry about dispacther's address, they ought to be running on different ports than listener anyway.
Don't use lsnrctl status for checkin services, lsnrctl services is for that.

Yes, in Oracle you can directly connect to your dispatcher as well if you want to (some people have resolved firewall port issues that way, by setting dispacther to run on specific port).
But generally you should use listener to connect. Listener acts just like a middle-man when estabilishing connection. When a new connection is made to listener and service "orcl" is requested for example, then listener checks whether it has a service "orcl" configured in it's confifguration (listener.ora) or has anyone registered this kind of service with it. If it finds the service, it also knows on which ports are the dispatchers or with which SID should it spawn a new server process.
