We have an oralce 816 client on Win NT with third party software connecting to Oracle816 DB on linux using "Merant ODBC" driver. I am getting lot of "TNS-12502: TNS:listener received no connect data from client messages" in the listener log file. I checked the tnsnames.ora on the client and it does have CONNECT_DATA specified. Does anyone know what is happening?
Thanks in Advance.
