if i have two seperate oracle instances on a unix host, do i need two seperate listeners for it?
the reason i'm asking this is that, i first created one oracle instance. then i did a ps -ef and checked that the listener was running. i also saw an entry for this listener in listener.ora.
then i created a second oracle instance on the same host. i did a ps -ef and saw that there was still only one listner. even listener.ora showed only one entry for a listener.
then i set my SID to the new instance and was able to connect to it using sqlplus.
so what's happening here?

and one another thing i noticed is that while the first instance has an entry in both listener.ora and tnsnames.ora, the second instance has an entry only in tnsnames.ora.

Not essential. Depends on the need.

Documented, expected and correct behaviour.
You did create the instance.
But did NOT create separate entries.
Edit the listener.ora and add entries
Or
use netca to do the same
