Home -> Community -> Mailing Lists -> Oracle-L -> RE: Multiple Listener
Separate listeners by Oracle version won't save your a&& if you take

separate home just for the listener, actually probably two and run
two listeners - of the same highest version - for all databases of
all versions to avoid a SPOF.
