Is anyone else out there running both a 10.2 and a 9.2 listener on the same port? Now that I've successfully upgraded my dev database from 10.1 to 10.2 I'm having listener issues (Solaris 2.9). Previously I was running 3 listeners on the same port with no problems (2 of them 9.2 one of them 10.1). When I try to start the listener for the 10.2 database it complains that there is already a listener running on that port: $ lsnrctl start listener_mds LSNRCTL for Solaris: Version 10.2.0.1.0 - Production on 19-SEP-2005 20:37:49 Copyright (c) 1991, 2005, Oracle. All rights reserved. TNS-01106: Listener using listener name listener_rtb has already been started I'm using the same host and key settings that worked on the 10.1 instance: LISTENER_MDS = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = mdsdev)(PORT = 1526)) ) (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROCMDS)) ) ) ) SID_LIST_LISTENER_MDS = (SID_LIST = (SID_DESC = (ORACLE_HOME = /oracle/mds/product/10.2.0) (SID_NAME = mdsdb) ) ) Thanks, Jay Miller ----------------------------------------- This message is confidential and sent by TD Waterhouse solely for use by the intended recipient.
