ORA 12224 - TNS: No Listener problem

81522Apr 19 2002

Hi there,
I have SQL*Plus working on client A (Sun Solaris, 9i), connecting to server C (Windows NT, 7.3.4)
From client B (Sun Solaris, 8.0.6), trying to connect to server C using the same TNSNAMES.ORA, same user & instance, I get the error :
ORA-12224: TNS:no Listener

This error, to me, means that the Oracle listener on server C is not working. Which is not possible, because it does work from client A !

Where did I go wrong ?
Could this mean that client B does not have network access to server C (client B is in DMZ, but should have all required accesses) ?

Thanks in advance !
Best regards,
Jerome
