Hi there,

I have an obscure problem.
I moved my oracle instance (8.1.7) from one subnet to another (changed on server tnsnames.ora, listener.ora, tnsnames on clients) and now only a few seconds after startup, sqlplus and other clients can connect. After some seconds, I get errors on client side, but tnsping reports no errors.

The error messages are :
client:
ORA-12545: Connect failed because target host or object does not exist

sqlnet.log (client):

Fatal NI connect error 12545, connecting to:

(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=132.187.167.132)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=DBMSPEC)(CID=(PROGRAM=)(HOST=wviz036)(USER=sunny))))

VERSION INFORMATION:

         TNS for Linux: Version 9.2.0.1.0 - Production

     TNS-00515: Connect failed because target host or object does not exist
     nt secondary err code: 2
     nt OS err code: 0


Server - oracle instance:
     no messages

Server - listener:

(ADDRESS=(PROTOCOL=tcp)(HOST=132.187.167.36)(PORT=40563)) * establish
DBMSPEC * 0

Whats wrong and how can I fix it? BTW: we do not want to upgrade from this version, if there is a solution for the reported problem.

thanks in advance.
