Please help with ESQL/C connectivity!

Configuration: ESQL/C 6.0 client installed on SPARC Solaris 2.4, trying to talk to Informix On-line Dynamic Server 6.0 installed on an IBM RS/6000 box. I have the following entry in the sqlhosts file on the client and the server: INFORM60 onsoctcp pulsar inform60 ("pulsar" is the name of the RS/6000 box) I have the following entry in the /etc/services file on the client and the server: inform60 3805/tcp On the client, I have the INFORMIXDIR environment variable set, as also the INFORMIXSERVER environment variable (set to INFORM60). Upon running the demo1 program, I get the following error upon attempting to connect to the database: 25597, You specified an unknown name or protocol. I have rechecked my setup a number of times, and have spent a frustrating time with Informix Support. They basically haven't been able to provide me with any new information, and don't know what I am doing wrong. I would be very grateful if I can get any input/suggestions/advice about what I should do/check. By the way, Windows 3.x and Windows NT ESQL/C clients can connect without any problems. Thanks in advance. Sanjay Agrawal ---- Platinum Technology 555 Twin Dolphin Drive #400 Redwood City, CA 94065 (415)594-8754 sagrawal@trinzic.com
