In 8i you do not need to include services in the listener. Listener itself can find out what databases are running and need it services

First Off, I would like to thank everyone who replied yesterday, your answers were most helpful!

Today, I am facing a new puzzle. I am currently running 3 databases on a server, but only two of them are listed in the listener.ora (bdw and rcvr). If I do a 'lsnrctl status' it shows a listener for all three databases (bdw rcvr and webprod). How is this possible? I have included my current listener.ora and output from 'lsnrctl status' ... Also, people who access these databases go through VIRTUAL ip's, i.e. the box itself has IP address xxx.xxx.xxx.11 the bdw ip is xxx.xxx.xxx.31 and the webprod ip is xxx.xxx.xxx.30
The reason for the virt ip's is for the fail over we have in place, so people do not have to reconfigure their machines when we move the databases around.

So by all rights I do not see how anyone can connect, but they are?!?!?!? WTH??? Thanks again guys ...
