connect informix 6.0 on Solaris with win98 PC problem

Can Anybody help me? I try to connect Informix Online 6.0 server on a Solaris host to a windows 98 PC. I want to use Borland C++ builder to create some client software. For the communication with the Informix server I got thier free SDK from www.intraware.com/informix. I first tried to connect with ODBC and then the Native option from Borland BDE but both options won't work. **************************************************************************** *********************** on the host: hostname : doorn In the services file : ontcp_prim 30001/tcp In the sqlhosts file : tcp_prim ontlitcp doorn ontcp_prim ONCONFIG : onconfig.doorn In the onconfig.doorn file : DBSERVERALIASES tcp_prim on the PC: C:\\WINDOWS\\Services: ontcp_prim 30001/tcp # Informix Server C:\\WINDOWS\\hosts: "valid_IP_address" doorn # Solaris Informix Setnet32: Enviroment: INFORMIXDIR=C\\Informix INFORMIXSERVER=tcp_prim Server information: Informix Server: tcp_prim Hostname: doorn Protocolname: olsoctcp Service Name: ontcp_prim Host Information: Current Host: doorn User Name: valid_user_name Password Option: Password PassWord: valid_password ODBC (INTERSOLV 3.11 32-BIT INFORMIX) Data Source Name: Informix_ODBC Description: Informix database Database Name: has (valid database) **************************************************************************** *********************** When I try to open the database (ODBC) with Borland BDE: BDE Error: 13058 Server Error: -7203 "[INTERSOLV][ODBC Informix driver][Informix]DBNLS is not set or LC_COLLATE must be 'C'."
