I would not recommend that since that could end up in a maintenance
nightmare in large production environments. I tend to prefer 2-3 listeners
per node of the RAC cluster as a failsafe, segregation of duties, and for
ease of maintenance and use the services framework to direct or
allow/disallow connections to a given instance of a database.

You could do that by changing the listener.ora and lsnrctl>reload.

For one thing, it allows us to turn off access to one instance at a time for
maintenance, for example. It allows us to assign a different port to each
instance. There are many advantages.

why do you require a listener per instance?

Hi, List,
I'd like to hear your input on how many listeners to run in a RAC
environment that will host 4 RAC databases. It'll be Oracle 10.2.0.3
<http://10.2.0.3/>
on RHEL 4 (all 64-bit). I am leaning to run just 1 listener, what is
your thoughts on this?
