Re: how many listeners to run?

Thank you all very much for taking your time to respond! I tend to agree with Freek D'Hooge to keep it simple and just use 1 listener and if I need to stop 1 application, I stop the corresponding database service of that application. My only concern with 1 listener is if it will be fast enough to respond to all the connection requests from the clients of all 4 databases not becoming a bottleneck. Any comment on here?

Also, I have a dumb question in here. If you do multiple listeners, how do you prevent 1 database automatically registers itself to all the running listeners? ie, how do you setup database A only registers itself to listener A, database B only registers itself to listener B?

Thanks again!
