-931 Cannot locate servicename service/tcp service in /etc/services.

The service servicename is not listed in the network configuration file /etc/services (UNIX) or \etc\services (DOS). Check the $INFORMIXDIR/etc/sqlhosts file, and check that the service name for the desired server is correct. If so, contact your network administrator to find out why the service is not known. If you are using IBM Informix OnLine for NetWare, check the \etc\services file on the client for the required entries.
