Mike: Did the networking setup of your database servers get updated (i.e. routing paths and DNS server IDs) prior to shutting down the old servers? I'd check on those as a point of possible problems.

[mailto:mkurth@xxxxxxxxxxx] Sent: Monday, October 18, 2004 11:50 AM To: 'oracle-l@xxxxxxxxxxxxx' Subject: Dns server retired- listeners hung We are retiring one of our dns servers. After rebooting new dns servers, we shutdown the "old" dns server, our database listeners either hang or crash. We have concluded that Oracle is caching the address of the old dns server. Does anyone know where, or how the listeners are tied to the dns servers?
