I have to connect my app to a customer's Informix 7.2 legacy database.

From what I was able to find out, in theory there should be a database service running on port 50000. The problem is that I cannot find any database service in the Operative System.

So far I'm only able to use dbaccess and perform queries from the command line.

I would like to use a database driver (such as http://code.google.com/p/ibm-db/) so my app can connect and query the database using a cursor, but since I cannot find any database service, apparently I can't...

Am I missing something here? Are there options I'm not considering?

Is it possible to have an Informix database in which the only interface is dbaccess?
