I agree with Tom, we are on a Sun UNIX box and we move the alert.log = (25+ databases) every week without any issues and have been doing it for = the last 5 years.=20 Rich -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of Mercadante, Thomas F (LABOR) Sent: Friday, June 10, 2005 8:39 AM To: Vitalis Jerome Cc: Paul.Vincent@xxxxxxxxx; oracle-l@xxxxxxxxxxxxx Subject: RE: Renaming / deleting listener.log and alert log Jerome.
