10.2 listener won 't start on same port as 9.2 listener 2005-09-20 - By JayMiller@(protected)
For the first question, there were two reasons for the request that we run
our listeners on the same port. The first was a request from security which
doesn't like to open the firewall for more than the minimum number of ports.
The second was from the SAs who are setting up the environment in sort of
semi-clustered fashion. The idea is that if the server should go down we
can easily distribute the 3 instances among other servers (storage is on a
SAN) simply by starting the individual instances and listeners on different
boxes.
This is also the reason we don't have just one listener for all instances.
We want the ability to bring up any instance on any box and the only way we
could do that would be if every listener on every box was configured for
every Oracle database in the company. I suppose we could do that, but
there's less management involved to maintaining one listener per instance
(otherwise whenever we added a new instance anywhere we'd need to modify and
restart all our listeners).
And it worked perfectly in 9.2 and 10.1 and when I restored the 10.1 version
last night.
Thanks,

Why would it be a problem to start it on a different port? In addition to
that, I believe that
10GR2 listener should be capable of handling 9.2 databases. Why do you need
to have one listener
per subnet?
