Our product is using DOA 3.3.1 with Oracle8i Personal Edition (8.1.5) under Windows NT. At a prospect's site (but not ours), the user gets the above "Initialization Error". I have traced the message to procedure InitOCI. He is able to log in with SQL*Plus (name=scott, pw=tiger, dbname=blank), so I suspect that the error message is wrong. Whatever SQL*Plus is doing right, I'd like to get DOA to do it, too, so that our program can start running. If that means updating to 3.3.2, or adding some lower-level code (and having DOA share the resulting connection), or anything else, I'm interested. Suggestions, please!
