Several possibilities: The host you specified in listener.ora does not exist or your machine is unable to recognize it. That usually happens when hosts are known under many nicknames and, of course, the host recognizes only some of them.
You are trying to resolve the hostname by using a name server (/etc/nsswitch.conf) and you don't have /etc/resolv.conf properly configured (at least "nameserver" entry must be configured). So, figure out what's wrong with your network setup and put 127.0.0.1 in listener.ora in the meantime. If that address is unreachable, then there is something seriously wrong with your box. -- Mladen Gogala Oracle DBA -----Original Message----- Reddy, Madhusudana Sent: Friday, August 15, 2003 2:14 PM To: Multiple recipients of list ORACLE-L Have you seen this before 15-AUG-2003 12:10:34 * (CONNECT_DATA=(SID=rtprod)(CID=(PROGRAM=dllhost.exe)(HOST=DS01IWEB)(USER=ser vice_mts))) * (ADDRESS=(PROTOCOL=tcp)(HOST=172.16.12.10)(PORT=1672)) * establish * rtprod * 12500 TNS-12500: TNS:listener failed to start a dedicated server process TNS-12545: Connect failed because target host or object does not exist TNS-12560: TNS:protocol adapter error TNS-00515: Connect failed because target host or object does not exist HPUX Error: 2: No such file or directory I have already bounced the listener 3 times .
