How to make both 'onipcshm' and 'onsoctcp' working ?

A liner help would be highly appreciated if somebody could advise. I'm trying to setup our BBS DB for running on DS (Linux), with NETTYPE set to both onipcshm/onsoctcp, so that it's available to the Windows client via ODBC. I tried the config as follows, but either one (ie. either onipcshm or onsoctcp) works but not both... Our BBS server program talk to DB via ipc, and Windows client need to talk to DB via tcp/ip so it seems that we need both connection types working. I suppose it's related to the NETTYPE setting on 'onconfig' file, but find it difficult to get the syntax right for NETTYPE setup. -- sqlhosts ss10 onipcshm ss10 olshm0 #ss10t onsoctcp ss10 oltcp0 -- onconfig # System Configuration SERVERNUM 0 NETTYPE onipcshm DBSERVERNAME ss10#DBSERVERALIASES ss10t DEADLOCK_TIMEOUT 60 RESIDENT 0 -- services #oltcp0 1499/tcp # Informix tcp Any suggestions would be highly appreciated. Cheers !
