Oracle Database Discussions

hi guys,

we have 20 databases on a database server. Every time I create a new database, I add the entry in the listener, but of course no one can connect to it until I restart the listener so that it picks it up.

I read that if I restart the listener then it would not affect connected users, but I am afraid of testing it out in case the connected users process gets messed up.

if the above is true, can someone please explain how this happens behind the scenes?

thanks
