The advice I got from OTS some years ago, like with the release of 8.0, was to use one listener for all databases on a single server, just use the latest listener installed as they were backwards compatible. That advice has been working extremely well ever since. So my question would be why do you want a separate listener, unless you've got two or more IP addresses, and consequently NIC's, for one server? _____ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Gogala, Mladen Sent: Wednesday, September 21, 2005 11:20 AM To: 'JayMiller@xxxxxxxxxxxxxxxx'; oracle-l@xxxxxxxxxxxxx Subject: RE: 10.2 listener won't start on same port as 9.2 listener Oracle is, quite obviously, listening to my advice, even if some listers are not. -- Mladen Gogala Ext. 121 _____ From: JayMiller@xxxxxxxxxxxxxxxx [mailto:JayMiller@xxxxxxxxxxxxxxxx] Sent: Tuesday, September 20, 2005 6:07 PM To: oracle-l@xxxxxxxxxxxxx Subject: RE: 10.2 listener won't start on same port as 9.2 listener Well, I just got the answer from Oracle and apparently 10.2 is purposely not allowing you to do this any more. It was done as a fix for another bug and this behavior will be backported to earlier versions in future releases. Looks like we're going to have to go with a single listener, like it or not. Sigh.
