Informix and ODBC
A user with Informix SE 7.22 on SCO UNIX wanted ODBC access from NT/95 clients (e.g. Excel) and asked which connectivity product to buy and what to enter in the ODBC DSN fields. Replies said the installed Client SDK (just its ODBC driver part) is enough, and explained the fields: the database name, the sqlhosts dbservername, the host's network name (resolvable in the hosts file), the service name/port listed in /etc/services, and protocol sesoctcp for SE (olsoctcp for OnLine), plus running sqlexecd as the listener. The poster then reported that his sesoctcp listener failed with error 25507 (unknown service name or protocol) while setlitcp worked but isn't offered in setnet32; no resolution to that follow-up is recorded in the thread.

really really simple i know... i have a SCO unix server running Informix SE 722.uc3 and 4gl 7.20ud6 we have nt and 95 workstations that require odbc access from simple program like MS-Excel etc. do i need to get informix-net, informix-connect , informix client or informix-client-sdk ? i have informix-client-sdk installed on NT workstation and tried simply creating a datasource in 32 bit odbc but i am not 100% sure of what to enter i.e. , it wants: database server host service protocol can anyone offer some tips Cheers Noel

You must also start a network listener ($INFORMIXDIR/lib/sqlexecd <service> ) on the server if it is not already running. Art S. Kagel

Connect and Client SDK will give you one, but the latest (release 3.3) is only in SDK (release 2.30). You don't need to install the whole SDK, just the ODBC part. > > i have informix-client-sdk installed on NT workstation and > tried simply creating a datasource in 32 bit odbc > but i am not 100% sure of what to enter > > i.e. , it wants: > database Database name > server Informix server name > host IP host name (or IP address) > service most probably 'turbo'. Check you \\windows\\system32\\drivers\\etc\\services file. Make sure it has a line that starts with turbo (probably at the end). > protocol olsoctcp -- Bashar Chalabi CTL, London
Art,
here is sample from my sqlhosts file on unix server
pps_se setlitcp develops pps_service
remas_se sesoctcp develops remas_service
the sesoctcp entry will not start... see error here...
--------------------------------------------------------------------
1999-10-06 11:42:01.890000 Starting Daemon INFORMIX-SQL Version 7.22.UC3

the setlitcp start ok and we can connect on unix server from dbaccess for
example
the setnet32 utility only has SEIPCIP, SESOCSPX , and SESOCTCP
so SESOCTCP is available for selection on setnet32 util but will not start
on
unix server. and SETLITCP starts ok on unix server but is not available in
setnet32 util ?
any ideas
