Dick,

Well, I've not seen the bug you describe and we have over 20 db's in one listener on several different boxes. We are in 8.1.6 on Compaq Tru64.

We did have a problem trying to get one listener in 8.1.6 to listed for 8.0.x and 7.3.x databases and WWS discovered that a bug they thought was fixed in 8i was not fixed for Compaq.
We're now looking at OID. Any horror/success stories out there?

Stephen

>>>Alex, This gets down to the amount of trust your damagement has in you. If theyare more tempted to listen to outside assertions that you have already heard,then it's time to move on because your being treated like a trained monkey. Mymanagement does ask questions on this type of subject when they've heardsomething new outside. It's normally just tossed in my direction as a "Hey Iheard that these folks are doing this. What do you think?". In which case Inormally find out what their doing & why and what Oracle says about it as well. If it does not make sense, it ends up in the round file & there is no morediscussion. It also helps to have management types who have some knowledge ofthe technology. The result is less of the problem you state. From a listener perspective, there is only one absolutely good reason thatI've found to run more than one listener per node & that is that after you pass10 DB's in one listener it appears to run out of memory & won't listen for theothers. I did find a bug on Metalink on the subject, but it was suppose to havebeen fixed in 8.0.6 though I've not verified that. Dick

If your damager ask youhow many listeners you are running and you answer one and he/she ( no sexizm:-)) heard that someone running 2 or 3 ( from another moro... err damager) -how would you explain why you are running only one. I hope that Ross can add more reasons to run at least 2 or better 3listeners.Alex Hillman-----Original

You have 3 littledatabases and one big bad listener whichs huffs and puffs and connects your clients to the instance of their choice. What would you benefit fromhaving 3 listeners?> -----Original Message-----> From: Edward W. Carr [<A
